     former employee of Bankers Insurance Company (“Defendant”), granting summary

     judgment in favor of Defendant, and denying Plaintiffs’ motion for reconsideration.

     We affirm the orders of the trial court.

                                      I.      Background

¶2         In March 2015, Mickey Snow and his wife, a native of Thailand, made

     arrangements to travel to Bangkok, Thailand. They originally planned to depart on

     26 October 2015 and return on 11 November 2015. Mr. Snow lives in Eden, North

     Carolina, and owns a second home in Ormond Beach, Florida. He planned to depart

     from Daytona, Florida, near his home in Ormond Beach, and make a connection in

     Atlanta, Georgia, before flying to Bangkok.

¶3         Mr. Snow subsequently learned that he had become the subject of a criminal

     investigation involving the sexual exploitation and abuse of an underaged girl. On

     Thursday, 10 September 2015, Thomas Woodall, another individual implicated in the

     investigation, was arrested and charged with various sex crimes.

¶4         The next day, Friday, 11 September 2015, Mr. Snow changed his travel plans.

     At an approximate cost of $2,600 per ticket, he caused his reservations to be changed

     to a direct flight from Atlanta to Bangkok departing Monday, 14 September 2015 and

     returning Wednesday, 30 September 2015. Then he drove to Atlanta with his wife

     and they flew to Thailand on Monday, 14 September 2015.

¶5         On 5 October 2015, Mr. Snow was indicted by a Rockingham County grand

                                        2022-NCCOA-130

                                       Opinion of the Court



     jury with the Class D felony of patronizing a prostitute with a severe or profound

     mental disability. See N.C. Gen. Stat. § 14-205.2(d) (2021). He was subsequently

     indicted with six counts of statutory rape/sexual offense of a 13-, 14-, or 15-year-old

     by a defendant more than six years older than the victim, 10 counts of patronizing a

     prostitute, four counts of second-degree forcible sexual offense, and six counts of

     promoting the prostitution of a minor.

¶6         At the time, Mr. Snow was still abroad. After he was indicted, he left Bangkok

     for Costa Rica by way of Holland and Panama. At some point, he was detained by

     authorities in Panama and forced to return to Holland, where he was then forced to

     return to Bangkok. His return ticket was changed from 30 September 2015 to 1

     November 2015, but it was never used.

¶7         On or about 24 November 2015, Mr. Snow was arrested in Thailand and turned

     over by Thai officials to United States law enforcement. He was then returned to the

     United States and incarcerated in the Rockingham County Jail.             At his first

     appearance before a Rockingham County magistrate, his bond was set at $25 million.

¶8         On 16 December 2015, Defendant posted bond on Mr. Snow’s behalf in

     exchange for a $1 million bond premium and Mr. Snow was released from jail. As a

     condition of his release, Mr. Snow was required to submit to electronic house arrest,

     including GPS monitoring. As collateral for the bond, Plaintiffs provided Defendant

     with $20 million in cash and pledged real estate worth at least $5 million.

                                         Opinion of the Court



¶9           The day after his release from jail, Mr. Snow executed a Bail Bond Application

       and Agreement.     The terms and conditions of the Bail Bond Application and

       Agreement state, amongst other things, that “[t]he [bond] premium is fully earned

       upon your release from custody[,]” and that

                    the Surety shall have the right to immediately apprehend,
                    arrest, and surrender you, and you shall have no right to
                    any refund of premium whatsoever . . . [if] you commit any
                    act that constitutes reasonable evidence of your intention
                    to cause a forfeiture of the Bond . . . [or] you are arrested
                    and incarcerated for any other offense (other than a minor
                    traffic offense)[.]

¶ 10         For the next year and a half, Mr. Snow was free on bail, subject to the

       conditions of his electronic house arrest, including GPS monitoring.

¶ 11         On 28 August 2017, Mr. Snow moved the trial court to reduce the amount of

       his bond. The court allowed the motion, reducing the bond to $15 million in an 8

       September 2017 order.      The court ordered Mr. Snow to continue to submit to

       electronic house arrest and electronic monitoring, but allowed him to travel outside

       the county to meet with his attorney, and outside the state for medical treatment,

       provided he first notify the District Attorney’s office and obtain approval and wear an

       electronic monitor during any travel for medical treatment. Finally, the court ordered

       that if Mr. Snow violated the 8 September 2017 order setting the conditions of his

       pre-trial release, he “be immediately arrested and held in custody without bond until

       such time as the Court can set any new conditions of pre-trial release under N.C.G.S.

                                            Opinion of the Court



       § 15A-534(f).” Defendant thereafter released Plaintiffs’ real property collateral and

       $5 million of the cash collateral.

¶ 12         On 15 September 2017, Mr. Snow moved for the trial court to allow him to

       travel to Jacksonville, Florida, for medical appointments on 20 and 21 September

       2017 at the Mayo Clinic. He requested that the court allow him to drive and break

       up the drive into two days, allowing him an additional day to recuperate after each

       leg of the trip. He also requested that he be allowed to make the trip without

       electronic monitoring. Initially, the State objected, arguing that it had not received

       the notice required by the 8 September 2017 order, that the three days before and

       after the medical appointments were excessive, and that relieving Mr. Snow of his

       obligation to wear an electronic monitor was improper. The State subsequently

       withdrew its objection, provided Mr. Snow submitted to electronic monitoring the

       entire time, as required by the 8 September 2017 order. The court granted Mr. Snow’s

       request in part, allowing him to travel to Florida for the appointments, but refusing

       to relieve him of electronic monitoring.

¶ 13         During the trip to Florida, the Rockingham County Sheriff’s Office lost track

       of Mr. Snow. The battery in his electronic monitor died and remained dead for two

       hours after his medical appointment in Jacksonville on 21 September 2017. Mr.

       Snow’s last known location before the battery died was an Outback Steakhouse,

       where he arrived at 7:16 p.m.        The next location tracked by the monitor was Mr.

       Snow’s home in Ormond Beach, where he returned and connected the monitor’s

       battery to its charger at 9:09 p.m.

¶ 14          On 25 September 2017, a magistrate issued an order for arrest for Mr. Snow

       for alleged violations of the conditions of his pre-trial release. Mr. Snow was arrested

       by a deputy from the Rockingham County Sheriff’s Office, and at his first appearance

       in Rockingham County District Court for the arrest the following day, the district

       court ordered that Mr. Snow be held without bond until a hearing in superior court

       before Judge Nathaniel Poovey, the judge who had granted Mr. Snow’s request to

       leave the state for medical treatment.2

¶ 15          On 29 September 2017, Defendant caused a Surrender of Defendant by Surety

       form (“Surrender Form”) to be filed in Rockingham County Superior Court through

       its local bail agent. The form stated that it was for a “pre-breach surrender” and that

       the surrender was being made “before a breach of the bond” and “before there has

       been a breach of the bond obligation.” Defendant thereby requested “exoneration

       from the bond obligation[.]”

¶ 16          On 2 October 2017, the State moved for the trial court to revoke the conditions

       of Mr. Snow’s pre-trial release.         The State’s motion came on for hearing in

       Rockingham County Superior Court before the Honorable Nathaniel Poovey on 4



              2 Mr. Snow’s first appearance occurred in district court because the only superior
       court judge available at the time recused himself.

                                          Opinion of the Court



       October 2017. Judge Poovey denied the State’s motion, finding that Mr. Snow did not

       violate the conditions of his pre-trial release during the Florida trip. The court

       therefore ordered that Mr. Snow be released from jail with the same bond and under

       the same conditions as in the 8 September 2017 order.

¶ 17          The next day, on 5 October 2017, Defendant posted a re-written $15 million

       bond and Mr. Snow was released. Mr. Snow was not charged an additional bond

       premium for the re-written bond. While he was free on bond for the next nine months,

       Mr. Snow never requested a return of his bond premium or a return of his collateral.

¶ 18          On 19 July 2018, Mr. Snow pleaded guilty to a single count of the Class F felony

       of aiding and abetting the prostitution of a minor, and the State dismissed all the

       other charges against him. Mr. Snow’s defense counsel informed Defendant that the

       criminal matters had been resolved, and Defendant released the remaining $15

       million in collateral.

¶ 19          A little over a month later, in a 28 August 2018 letter, Mr. Snow for the first

       time took the position that Defendant was required to return the $15 million in

       collateral within 72 hours of the filing the Surrender Form on 29 September 2017 and

       that he was entitled to a refund of the $1 million bond premium because the

       Surrender Form stated that Defendant’s surrender on the original bond was a pre-

       breach surrender and Judge Poovey ruled on 4 October 2017 that Mr. Snow had not

       violated the terms of his pre-trial release. In other words, just over a month after his

                                          Opinion of the Court



       criminal charges were resolved—almost a year after the Surrender Form was filed—

       and after being free on bail for nearly three years while the criminal charges against

       him were pending (with the exception of 11 days he spent in jail after his 2017 Florida

       trip), Mr. Snow argued that Defendant was required to return him $16 million

       approximately a year earlier. Receiving no response, Mr. Snow sent a second letter

       on 7 January 2019, threatening legal action.

¶ 20         Defendant disputed both of Mr. Snow’s positions in a 15 January 2019 reply,

       explaining that it posted a new bond without charging Mr. Snow any additional

       premium after learning he was eligible for bail again after the 4 October 2017

       hearing, that it did so after consulting with his attorneys, and that the $1 million

       premium on the original bond was earned in full upon the posting of that bond,

       consistent with the provision of the 17 December 2015 Bail Bond Application and

       Agreement regarding “[t]he [bond] premium [being] fully earned upon [his] release

       from custody.”

¶ 21         On 6 May 2019, Plaintiffs initiated this action in Brunswick County Superior

       Court. In their verified complaint, Plaintiffs asserted six causes of action, requesting

       a declaratory judgment, return of the $1 million bond premium, disgorgement of any

       investment income earned by Defendant with the $16 million allegedly wrongfully

       retained after the 29 September 2017 filing of the Surrender Form, attorney’s fees,

       pre-judgment interest, treble damages under the Unfair and Deceptive Practices Act,

       and punitive damages. On 8 July 2019, Defendant moved to dismiss the complaint,

       and alternatively, answered, asserting affirmative defenses, including waiver,

       estoppel, and unjust enrichment.

¶ 22          On 27 July 2020, Plaintiffs moved for summary judgment. On 31 July 2020,

       Defendant moved for summary judgment. On 31 July 2020, Defendant also moved

       to disqualify an expert identified by Plaintiffs in their expert disclosures and strike

       an affidavit filed by the expert on 27 July 2020. On 10 August 2020, Plaintiffs filed

       a motion to strike an affidavit by a former employee of Defendant filed in support of

       Defendant’s motion for summary judgment on 31 July 2020.

¶ 23          These motions came on for hearing before the Honorable Jason C. Disbrow in

       Brunswick County Superior Court on 10 August 2020. In an order entered 17 August

       2020, the trial court granted Defendant’s motion to disqualify and strike the affidavit

       of Plaintiffs’ expert, denied Plaintiffs’ motion to strike,3 and entered summary

       judgment in favor of Defendant.

¶ 24          On 27 August 2020, Plaintiffs moved for the court to reconsider its 17 August

       2020 order pursuant to Rules 58, 59, and 60 of the North Carolina Rules of Civil




              3Plaintiffs offer no argument in their brief regarding the trial court’s denial of their
       motion to strike. Any error in the denial of this motion is therefore deemed abandoned. See

                                            II.   Analysis

¶ 25          This appeal presents a question of first impression. Because it arises in a novel

       context, we begin with an introduction of the relevant statutory framework. Then we

       turn to resolution of this question, as well as the other issue raised by the appeal.

       A. Introduction

¶ 26          A criminal defendant “charged with a noncapital offense must have conditions

       of pretrial release determined” by a judge. N.C. Gen. Stat. § 15A-533(b) (2021). One

       condition available to the judge is the execution of an appearance bond secured by a

       cash deposit. Id. § 15A-534(a)(4). The security for such appearance, called “bail,” is

       to ensure the defendant’s appearance in court. See id. § 58-71-1(2) (defining a “[b]ail

       bond” as “[a]n undertaking by the principal to appear in court as required upon

       penalty of forfeiting bail to the State in a stated amount”). If the defendant fails to




              4Plaintiffs also offer no argument in their brief regarding the trial court’s denial of
       their motion for reconsideration. Accordingly, any error in the denial of this motion is deemed
       abandoned. See N.C. R. App. P. 28(a).

                                          Opinion of the Court



       appear for a court hearing, the bond amount is forfeited. Id. § 15A-544.3(a).

¶ 27         A defendant compensates a bail bondsman or bond surety for the risk that the

       defendant will not appear, or otherwise violate the conditions of the defendant’s bond,

       through payment of a bond premium. See id. § 58-71-1(6a) (defining “premium” as

       “[a]n amount of money paid in exchange for a bail bondsman’s services in writing a

       bail bond”). In general, a bond premium is not returnable once “an agreement has

       been entered into between a defendant and a surety,” even if the amount of the bond

       is later reduced. Id. § 58-71-16. However,

                    [a]t any time before there has been a breach of the
                    undertaking in any type of bail or fine and cash bond the
                    surety may surrender the defendant to the sheriff of the
                    county in which the defendant is bonded to appear or to the
                    sheriff where the defendant was bonded; in such case the
                    full premium shall be returned within 72 hours after the
                    surrender.

       Id. § 58-71-20. Interpreting this provision, our Supreme Court has observed that

       under this statute, if a bondsman “rescind[s] the bail contract and surrender[s] [the]

       defendant . . . without cause or reason[,]” he becomes liable in contract for the amount

       of the premium that is not returned to the defendant. Shore v. Farmer, 351 N.C. 166,

       171, 522 S.E.2d 73, 76 (1999) (emphasis added).

¶ 28         North Carolina General Statute § 58-71-20 goes on to provide, however, that a

       “defendant may be surrendered without the return of [the] premium for the bond if

       the defendant . . . [v]iolates any order of the court.” N.C. Gen. Stat. § 58-71-20(5)

                                          Opinion of the Court



       (2021). Whether a bond premium must be returned within 72 hours of a surrender

       thus depends, as a general proposition, on whether the surrender occurs because of a

       breach of a condition of the bond. See id. Section 58-71-20 thus makes the necessity

       of the return of a bond premium within the statutorily mandated 72 hours dependent

       on a determination—whether a suspected breach constitutes a breach—that may not

       occur, and in this case did not occur, within 72 hours of the surrender.

¶ 29         If the surrender is not because of a breach of a condition of the bond, it is

       considered a pre-breach surrender. See id. § 15A-540(a) (“Before there has been a

       breach of the conditions of a bail bond, the surety may surrender the defendant[.]”).

       If the surrender is because of a breach of a condition of the bond, on the other hand,

       it is considered a post-breach surrender. See id. § 15A-540(b) (“After there has been

       a breach of the conditions of a bail bond, . . . [a] surety may arrest the defendant . . .

       [or] may surrender a defendant who is already in the custody of any sheriff[.]”).

¶ 30         When a defendant is surrendered because of a suspected breach, “the sheriff

       shall without unnecessary delay take the defendant before a judicial official, along

       with a copy of the undertaking received from the surety and a copy of the receipt

       provided to the surety.” Id. § 15A-540(c). “The judicial official shall then determine

       whether the defendant is again entitled to release and, if so, upon what conditions.”

                                         Opinion of the Court



       for failure to return a bond premium to a defendant within the 72 hours prescribed

       by § 58-71-20 where the defendant is surrendered by the surety because of an alleged

       breach of the conditions of the defendant’s pre-trial release (which, by virtue of the

       bail contract with the surety, would be a breach of a condition of the bond) but the

       trial court subsequently determines that the suspected breach, did not, in fact,

       constitute a breach after all. That is, if a surety rescinds its bail contract with a

       defendant because of a good faith mistake about whether there has been a breach

       and, after learning of the mistake, re-writes the bond and gives the defendant the

       benefit of his bargain by waiving any additional premium, returning the surety and

       defendant to the status quo before the alleged breach, can the surety escape liability

       under § 58-71-20 for failing to return the bond premium within 72 hours of the

       surrender? We hold that it can. If the surety returns both itself and the defendant

       to the same position each occupied before the suspected breach, and the defendant is

       released from custody and does not raise any objection or request a return of the bond

       premium before he is released, we hold that the defendant is estopped from later

       seeking recovery of the bond premium.

                    there is no genuine issue as to any material fact, and the

                    to prevail on a summary judgment motion, the moving

                    plaintiff’s claim is nonexistent; (2) plaintiff cannot produce

                    plaintiff cannot surmount an affirmative defense which
                    would bar the claim. The trial court must construe all
                    evidence in the light most favorable to the non-moving

                                          Opinion of the Court



¶ 35         Plaintiffs are estopped from seeking recovery of the bond premium for the

       original bond because Mr. Snow received the benefit of the re-written bond and

       Plaintiffs failed to notify Defendant that Mr. Snow did not wish to receive this benefit

       within a reasonable amount of time. This holding is based on three related equitable

       doctrines: (1) estoppel; (2) election; and (3) unjust enrichment.

          1. Estoppel

¶ 36         “Broadly speaking, estoppel is a bar which precludes a person from denying or

       asserting anything to the contrary of that which has, in contemplation of law, been

       established as the truth.” Whitacre P’ship v. Biosignia, Inc., 358 N.C. 1, 13, 591

       S.E.2d 870, 879 (2004) (internal marks and citation omitted). It is “a means of

       preventing a party from asserting a legal claim or defense which is contrary to or

       inconsistent with his prior actions or conduct.” Godley v. Pitt Cnty., 306 N.C. 357,

       360, 293 S.E.2d 167, 169 (1982). “Where a party engages in positive acts that amount

       to ratification resulting in prejudice to an innocent party, the circumstances may give

       rise to estoppel.” Chance v. Henderson, 134 N.C. App. 657, 664, 518 S.E.2d 780, 784

       (1999) (citation omitted). Likewise, “unreasonable delay after notice[] resulting in

       prejudice to innocent parties . . . [can] work an estoppel.” Howard v. Boyce, 254 N.C.

       255, 266, 118 S.E.2d 897, 905 (1961). “[W]hen only one inference can reasonably be

       drawn from the undisputed facts, estoppel becomes a question of law, properly

       decided by this Court.” Tarlton v. Stidham, 122 N.C. App. 77, 82, 469 S.E.2d 38, 42

       (1996) (citation omitted).

¶ 37         “While estoppel in its broadest sense predates the American colonial

       experience, . . . North Carolina courts have [] long recognized the doctrine of equitable

       estoppel, otherwise known as estoppel in pais.” Whitacre P’ship, 358 N.C. at 13-16,

       591 S.E.2d at 879-81. In general, equitable estoppel applies

                    when anyone, by his acts, representations, or admissions,
                    or by his silence when he ought to speak out, intentionally
                    or through culpable negligence induces another to believe
                    certain facts exist, and such other rightfully relies and acts
                    on such belief, so that he will be prejudiced if the former is
                    permitted to deny the existence of such facts.

       State Highway Comm’n v. Thornton, 271 N.C. 227, 240, 156 S.E.2d 248, 258 (1967)

       (cleaned up). Our Supreme Court has described equitable estoppel as “an application

       of the golden rule to the everyday affairs of men.” McNeely v. Walters, 211 N.C. 112,

       113, 189 S.E. 114, 115 (1937).

       Sneeden’s Sons, Inc. v. ZP No. 116, 190 N.C. App. 90, 96, 660 S.E.2d 204, 208 (2008).

       “Under quasi-estoppel doctrine, one is not permitted to injure another by taking a

       position inconsistent with prior conduct, regardless of whether the person had

       actually relied upon that conduct.” Mayer v. Mayer, 66 N.C. App. 522, 532, 311 S.E.2d

       659, 666 (1984). Likewise, “[u]nder a quasi-estoppel theory, a party who accepts a

       transaction or instrument and then accepts benefits under it may be estopped to take

       a later position inconsistent with the prior acceptance of that same transaction or

       instrument.” Whitacre P’ship, 358 N.C. at 18, 591 S.E.2d at 881-82. “[T]he essential

       purpose of quasi-estoppel . . . is to prevent a party from benefitting by taking two

       clearly inconsistent positions.” B & F Slosman v. Sonopress, Inc., 148 N.C. App. 81,

       88, 557 S.E.2d 176, 181 (2001).

¶ 39         “The key distinction between quasi-estoppel and equitable estoppel is that the

       former may operate without detrimental reliance on the part of the party invoking

       the estoppel[,]” Whitacre P’ship, 358 N.C. at 18, 591 S.E.2d at 882, whereas “[u]nder

       ‘true’ estoppel, one party induces another to rely to his damage upon certain

       representations[,]” Chance, 134 N.C. App. at 665, 518 S.E.2d at 785. Quasi-estoppel

       is thus “directly grounded [] upon a party’s acquiescence or acceptance of payment or

       benefits, by virtue of which that party is thereafter prevented from maintaining a

       position inconsistent with those acts.” Godley, 306 N.C. at 361, 293 S.E.2d at 170.

       “[T]he acceptance of benefits precludes a subsequent inconsistent position, even

       where acceptance is involuntary, arises by necessity, or where . . . a party voluntarily

       accepts a benefit in order to avoid the risk of harm.” Shell Island Homeowners Ass’n,

       Inc. v. Tomlinson, 134 N.C. App. 217, 226, 517 S.E.2d 406, 413 (1999). While quasi-

       estoppel “is similar to equitable estoppel in that it may not be invoked by a stranger

       to the transaction where the prior position was asserted[,]” Whitacre P’ship, 358 N.C.

       at 19, 591 S.E.2d at 882, unlike equitable estoppel more generally, it is “inherently

       flexible and cannot be reduced to any rigid formulation[,]” id. at 18, 591 S.E.2d at

       882.

          2. Election

¶ 40          “North Carolina courts have long recognized and applied the election of

       remedies doctrine.” Id. at 19, 591 S.E.2d at 882.

                    The doctrine is founded on the principle that where by law
                    or by contract there is a choice of two remedies which
                    proceed upon opposite and irreconcilable claims of right,
                    the one taken must exclude and bar the prosecution of the
                    other. The doctrine precludes the assertion of inconsistent
                    positions by confining a party to the position which he first
                    adopts. Thus, a party asserting rights under a will, deed,
                    or contract is estopped, by claiming under it, to attack any
                    of its provisions. One who accepts the terms of an
                    instrument must accept the same as a whole; one cannot
                    accept part and reject the rest.

       Id. at 19-20, 591 S.E.2d at 882-83 (cleaned up). “[T]he doctrine of election is used to

       prevent double redress for a single wrong.” Id. at 20, 591 S.E.2d at 883 (internal

       marks and citation omitted).

          3. Estoppel Arises Here Because of the Benefit Conferred on Mr. Snow

¶ 41          Seeking recovery of the bond premium for the original bond almost a year after

       receiving the benefit of the re-written bond amounts to taking fundamentally

       inconsistent positions in connection with the bond. Plaintiffs essentially seek to

       retain the benefit of Defendant’s services without paying anything for this benefit.

       The relief requested by Plaintiffs thus conflicts not only “with the essential purpose

       of quasi-estoppel, which is to prevent a party from benefitting by taking two clearly

       inconsistent positions[,]” B & F Slosman, 148 N.C. App. at 88, 557 S.E.2d at 181, but

       also the doctrine of election, which “prevent[s] double redress for a single wrong[,]”

       Whitacre P’ship, 358 N.C. at 20, 591 S.E.2d at 883.

¶ 42         Four days after Mr. Snow was arrested for allegedly violating the conditions of

       his pre-trial release, when Defendant caused a Surrender Form to be filed in

       Rockingham County Superior Court on 29 September 2017, Plaintiffs had a decision

       to make. The Surrender Form stated that it was for a pre-breach surrender. If that

       was true, then under N.C. Gen. Stat. § 58-71-20, Plaintiffs were entitled to return of

       the $1 million bond premium within 72 hours. Plaintiffs could have demanded that

       Defendant return the bond premium. If Plaintiffs were dissatisfied with Defendant

       for surrendering Mr. Snow on 29 September 2017, they could have sought out a new

       surety to post bond for Mr. Snow, anticipating the return of the bond premium within

       72 hours and that the trial court would soon set new conditions of pre-trial release

       for Mr. Snow. And again, 72 hours after the Surrender Form was filed, having not

       received a return of the bond premium, if Plaintiffs or their counsel in fact believed

       that they were entitled to a return of the bond premium, the time was ripe to inform

       Defendant of that view.     Neither Mr. Snow, nor anyone acting on his behalf,

       communicated in any way to Defendant that Mr. Snow believed he was owed $1

       million by Defendant in late September 2017.

                                          Opinion of the Court



¶ 43         If any doubt lingered in the mind of Mr. Snow or his counsel about whether

       Plaintiffs were entitled to a return of the bond premium 72 hours after Defendant

       caused the Surrender Form to be filed in Rockingham County Superior Court, that

       doubt should have been removed when Judge Poovey denied the State’s motion to

       revoke the conditions of Mr. Snow’s pre-trial release on 4 October 2017. Judge

       Poovey’s ruling that Mr. Snow had not violated the terms of his pre-trial release

       during the 2017 Florida trip should have vindicated any belief Plaintiffs had that

       they were entitled to a return of the bond premium by at least the day beforehand—

       3 October 2017—after the 72 hours had elapsed. After all, the Surrender Form stated

       that it was for a pre-breach surrender, and the court had ruled that Mr. Snow had

       not, in fact, violated the conditions of his pre-trial release (and consequently, had not

       violated a condition of his bond), rejecting the State’s argument to the contrary. Yet,

       even after Judge Poovey ruled that Mr. Snow had not violated the terms of his pre-

       trial release during the 2017 Florida trip, neither Mr. Snow, nor anyone acting on his

       behalf, informed Defendant that Plaintiffs believed they were entitled to a return of

       the bond premium—a return that by that point, was at least a day overdue.

¶ 44         Instead, the next day, on 5 October 2017, Mr. Snow was released from custody

       after Defendant re-wrote Mr. Snow’s bond without charging an additional premium.

       Plaintiffs dispute whether Mr. Snow, or anyone acting on his behalf, expressly

       authorized Defendant to re-write the bond on 5 October 2017.             However, it is

                                          Opinion of the Court



       undisputed that Mr. Snow received the benefit of the re-written bond; he was released

       from custody the same day the bond was re-written. Moreover, “voluntariness is not

       an element under the doctrine of quasi estoppel.” Carolina Medicorp, Inc. v. Board

       of Trustees, 118 N.C. App. 485, 493, 456 S.E.2d 116, 121 (1995).

¶ 45         The benefit Mr. Snow received from the re-written bond was substantial. See,

       e.g., Vill. of Pinehurst v. Reg’l Invs. of Moore, Inc., 330 N.C. 725, 730, 412 S.E.2d 645,

       647 (1992) (noting that the benefit received must be substantial to support estoppel

       under a quasi-estoppel theory). In all, Mr. Snow was free on bail for nearly three

       years while the criminal charges against him were pending. He received the benefit

       of his bargain with Defendant. He chose to accept the benefit of the re-written bond

       without notifying Defendant within a reasonable amount of time that he believed he

       was entitled to a return of the bond premium for the original bond. He did not inform

       Defendant that he believed he was entitled to a return of the bond premium until 28

       August 2018, a month after his criminal charges were resolved—almost a year after

       Defendant re-wrote his bond without charging him an additional premium.

¶ 46         As our Court has observed, “[a]s much as in any area of the law, quasi estoppel

       cases turn on the particular facts of each case.” Mayer, 66 N.C. App. at 535, 311

       S.E.2d at 668. Mr. Snow elected to accept the benefit of the re-written bond, paid no

       additional premium for the re-written bond, and failed to notify Defendant within a

       reasonable amount of time that he did not wish to receive this benefit. We hold that

                                           Opinion of the Court



       Mr. Snow’s receipt of the benefit of his bargain with Defendant by being returned to

       the same position he occupied before the suspected breach of the conditions of his pre-

       trial release, coupled with Plaintiffs’ silence about their entitlement to a return of the

       bond premium or $15 million in collateral for almost a year, estops Plaintiffs from

       seeking return of the bond premium or any other relief requested in their verified

       complaint.   By virtue of Plaintiffs’ “acquiescence or acceptance of . . . benefits,”

       Plaintiffs are “prevented from maintaining a position inconsistent with those acts.”

       Godley, 306 N.C. at 361, 293 S.E.2d at 170. Accordingly, Plaintiffs’ “acceptance of

       benefits precludes [their] subsequent inconsistent position[s],” even though arguably,

       Mr. Snow received the benefit of the re-written bond “involuntar[ily], . . . by necessity,

       or where . . . [he] voluntarily accept[ed] a benefit in order to avoid the risk of harm.”

       Shell Island Homeowners Ass’n, 134 N.C. App. at 226, 517 S.E.2d at 413. Plaintiffs

       are therefore estopped from obtaining a return of the bond premium.

          4. Unjust Enrichment

¶ 47         We note that a contrary holding would result in Plaintiffs’ unjust enrichment.

       Indeed, recovery of any of the relief requested in Plaintiffs’ verified complaint would

       result in a windfall to Mr. Snow.

¶ 48         “The doctrine of unjust enrichment was devised by equity to exact the return

       of, or payment for, benefits received under circumstances where it would be unfair

       for the recipient to retain them without the contributor being repaid or compensated.”

       Collins v. Davis, 68 N.C. App. 588, 591, 315 S.E.2d 759, 761, aff’d, 312 N.C. 324, 321

       S.E.2d 892 (1984).

                    In order to establish a claim for unjust enrichment, a party
                    must have conferred a benefit on the other party. The
                    benefit must not have been conferred officiously, that is it
                    must not be conferred by an interference in the affairs of
                    the other party in a manner that is not justified in the
                    circumstances. The benefit must not be gratuitous and it
                    must be measurable. . . . A claim of this type is neither in
                    tort nor contract but is described as a claim in quasi
                    contract or a contract implied in law. A quasi contract or a
                    contract implied in law is not a contract. The claim is not
                    based on a promise but is imposed by law to prevent an
                    unjust enrichment.

       Booe v. Shadrick, 322 N.C. 567, 570, 369 S.E.2d 554, 556 (1988) (citations omitted).

¶ 49         For example, in the doctrine’s paradigmatic fact pattern—that of the mistaken

       improver—our Supreme Court has observed,

                    where one, under a mistake as to the location of his own
                    premises, in good faith, and without inexcusable
                    negligence, makes improvements upon the land of another,
                    and the latter, knowing of the making of the improvements,
                    but being himself ignorant of the mistake in location, fails
                    to make objection, the improver may obtain suitable relief
                    in equity.

       Rhyne v. Sheppard, 224 N.C. 734, 737, 32 S.E.2d 316, 318 (1944). In the case of the

       mistaken improver, the true owner “cannot retain a benefit which knowingly he has

       permitted another to confer upon him by mistake[,]” and an owner who “stands by

       and sees another erect improvements on the estate in good faith in the belief that he

       “claim[ing] such improvements after they are erected.” Id.

¶ 50         Plaintiffs stood by and watched Defendant in good faith return Mr. Snow to

       the position he occupied before the suspected breach of the terms of his pre-trial

       release without interposing to prevent Defendant from doing so.         See id.   After

       Defendant mistakenly rescinded the bond contract, Mr. Snow had “a choice of two

       remedies which proceed[ed] upon opposite and irreconcilable claims of right”—accept

       the restitution tendered to him by Defendant after learning of the mistake, or insist

       on a return of the bond premium when he did not receive it within 72 hours of the

       filing of the Surrender Form. Whitacre P’ship, 358 N.C. at 19, 591 S.E.2d at 883. The

       remedy chosen by Mr. Snow—acceptance of the benefit of the re-written bond, and

       return to the position he occupied before the suspected breach—“exclude[s] and bar[s]

       the prosecution of the other[,]” i.e., return of the bond premium. Id. By “preclud[ing]

       the assertion of inconsistent positions [and] confining a party to the position which

       he first adopts[,]” the doctrines of estoppel and election work to prevent Plaintiffs’

       unjust enrichment here. Id.

                                         Opinion of the Court



       An expert witness may only offer such testimony if

                    (1)    The testimony is based upon sufficient facts or data.

                    (2)  The testimony is the product of reliable principles
                    and methods.

                    (3)    The witness has applied the principles and methods
                    reliably to the facts of the case.

       reversed on appeal absent a showing of abuse of discretion.” Da Silva v. WakeMed,

       375 N.C. 1, 4, 846 S.E.2d 634, 638 (2020) (internal marks and citations omitted). “The

       standard of review remains the same whether the trial court has admitted or

       excluded the testimony—even when the exclusion of expert testimony results in

       summary judgment and thereby becomes outcome determinative.” Id. at 4-5, 846

       S.E.2d at 638 (internal marks and citations omitted). “However, when the pertinent

       inquiry on appeal is based on a question of law—such as whether the trial court

       properly interpreted and applied the language of a statute—we conduct de novo

       review.” Id. at 5, 846 S.E.2d at 638.

¶ 53         Plaintiffs argue that disqualifying retired Judge James D. Llewellyn as an

       expert and striking his 27 July 2020 affidavit was erroneous. Judge Llewellyn was

                                  Opinion of the Court



             substantial experience pertaining to pretrial release of
             criminal defendants, including, inter alia, pretrial release
             conditions, violations of pretrial release, bail bonds, bail
             bondsmen, surety companies, bond forfeitures, surrenders
             of criminal defendants by the surety, premiums paid by
             defendants in connection with their bonds, motions by the
             State to have defendants’ bonds revoked for violating their
             pretrial release conditions or other relief the State may
             seek, and matters addressed in N.C. Gen. Stat. 58-71-20.

(Emphasis in original.) Plaintiffs’ Rule 26(b)(4) disclosure regarding Judge Llewellyn

identified four opinions Judge Llewellyn intended to offer:

                   First, by virtue of Defendant’s surrender of Mr.
             Snow, Mr. Snow’s original bond was thereby terminated as
             a matter of law.

                   Second, by virtue of Judge Poovey’s ruling on or
             about 4 October 2017 that denied the State’s motion to
             revoke Mr. Snow’s bond, the Defendant should have
             immediately returned all of Plaintiffs’ 15 million dollars.
             Defendant’s retainage of Plaintiffs’ 15 million dollars until
             approximately ten (10) months later on or about 1 August
             2018 was improper.

                     Third, by virtue of Judge Poovey’s ruling on or about
             4 October 2017 that denied the State’s motion to revoke Mr.
             Snow’s bond, Judge Poovey issued a new bond for Mr.
             Snow’s pretrial release on the same terms as Mr. Snow’s
             terminated original bond and Defendant’s actions in
             connection with this second bond pertaining to Mr. Snow
             . . . were improper and unauthorized.

                    Fourth, by virtue of Judge Poovey’s ruling on or
             about 4 October 2017 that denied the State’s motion to
             revoke Mr. Snow’s bond, the Defendant should have fully
             returned and fully refunded Plaintiff’s bond premium of 1
             million dollars, at the very least, within 72 hours after
             entry of Judge Poovey’s ruling (thus, on or about 8 October

                    2017). Defendant’s refusal ever since approximately 8
                    October 2017 to the present to return Plaintiffs’ 1-million-
                    dollar bond premium it received from Plaintiffs was and
                    remains in violation of N.C. Gen. Stat. 58-71-20.

¶ 54         While Plaintiffs concede that an expert “may not testify that [] a particular

       legal conclusion or standard has or has not been met[,]” State v. Smith, 315 N.C. 76,

       100, 337 S.E.2d 833, 849 (1985), they argue that the opinions in Plaintiffs’ expert

       disclosures, the opinions offered by Judge Llewellyn during his deposition, and the

       opinions offered in the 27 July 2020 affidavit do not run afoul of this prohibition. We

       disagree.

¶ 55         Plaintiffs’ Rule 26(b)(4) disclosure, Judge Llewellyn’s deposition testimony,

       and the 27 July 2020 affidavit demonstrate that the only opinions Judge Llewellyn

       was prepared to offer were that “a particular legal conclusion or standard ha[d] or

       ha[d] not been met.” Smith, 315 N.C. at 100, 337 S.E.2d at 849. These materials also

       demonstrate that these opinions were being offered solely on the basis of Judge

       Llewellyn’s personal knowledge and experience as a 21-year North Carolina Superior

       Court Judge, which does not meet the requirements of Rule 702. Specifically, Judge

       Llewellyn’s deposition testimony demonstrates that his opinions were not “based

       upon sufficient facts or data[,]” were not “the product of reliable principles and

       methods[,]” and did not demonstrate that the relevant “principles and methods [had

       been applied] reliably to the facts of the case[,]” as Rule 702 requires. N.C. Gen. Stat.

                                         Opinion of the Court



       § 8C-1, Rule 702(a) (2021). For example, Judge Llewellyn testified at his deposition

       that this was the first case in which he had been engaged as an expert witness on any

       subject; that he had never given any lectures or seminars to judges or attorneys on

       the subject of bail bonds; that he had never published any written work on bail bonds;

       that he had never peer reviewed any article or writing on bail bonds; that by the date

       of his deposition, he had not prepared any expert report; that the opinions identified

       in the Rule 26(b)(4) disclosure were the only opinions he intended to offer; and that

       these opinions were based only on application of North Carolina statutes to the facts

       of this case. We therefore hold that the trial court did not err, much less abuse its

       discretion, in disqualifying Judge Llewellyn as an expert and striking his testimony.

                                      III.     Conclusion

¶ 56          We hold that Plaintiffs are estopped from recovering the bond premium

       because Defendant rescinded its bail contract with Mr. Snow because of a good faith

       mistake about whether Mr. Snow had breached a condition of his bond and, after

       learning of the mistake, re-wrote the bond and gave Mr. Snow the benefit of his

       bargain by waiving any additional premium. Mr. Snow elected to accept the benefit

       of the re-written bond and failed to notify Defendant within a reasonable amount of

       time that he did not wish to receive this benefit. We conclude that Mr. Snow’s election

       to accept the benefit of the re-written bond precludes him from adopting the

       inconsistent position he has taken in this action, and that our holding prevents
