OPINION OF THE COURT
Justice CASTILLE.This matter comes before this Court on. a Petition for Certification of Questions of Law from the United States Court of Appeals for the Third Circuit. This Court granted the petition, which raises three questions: (1) whether a drawee bank obtains “possession” of any property, as defined by Pa.R.C.P. 3101, of a customer who physically provides the drawee bank’s teller with cash and checks, in exchange for the issuance of a bank cashier’s check, when those funds are never deposited into the customer’s account at the drawee bank; (2) whether a garnishee bank, which receives “possession” of the property of a judgment debtor after being served with a writ *630of execution, has a duty under Pa.R.C.P. 3111(c) “restraining [it] from paying any debt” to that judgment debtor in exchange for that property, even if that “debt” arises during a transaction with a brief duration akin to that of a sales transaction; and (3) whether the public policy underlying Pennsylvania garnishment law requires a garnishee bank, on notice of a judgment order against a depositor by Writ of Execution and whose accounts are thereby held, to refrain from engaging in transactions with that judgment debtor which permit the judgment debtor to avoid the garnishment of its assets, and thereby the debtor’s obligation to pay its judgment creditor, to the financial benefit of the garnishee bank.
The salient facts are undisputed. Appellee, Herzog Brothers Trucking Inc. (Herzog Brothers), is a wholesale distributor of motor fuel products. On June 5, 1996, in an unrelated action, appellant, Witco Corporation (Witco), obtained a default judgment against Herzog Brothers in the amount of $509,216.52 plus costs in the United States District Court for the Western District of Pennsylvania. On July 5, 1996, in an effort to collect the judgment, Witco served a writ of execution upon National City Bank of Pennsylvania (Bank) as potential garnishee. In response to interrogatories from Witco, the Bank indicated that it held and had frozen $1,379.52 in a checking account belonging to Herzog Brothers.
Witco deposed Gary Herzog, Herzog Brother’s president and sole shareholder, who testified that subsequent to the service of the writ of execution upon the Bank but before entry of judgment against the Bank, a period spanning from July 5,1996 to August 11,1997, Herzog Brothers purchased at least 131 cashiers’ checks from the Bank, using personal checks and cash. As to each purchase of a cashier’s check, Herzog presented his personal checks or cash to the Bank at the teller windows whereupon the Bank would issue “official checks” drawn on the Bank and payable to various designees specified by Herzog. The aggregate value of these checks exceeds $6,000,000. During the same time period, the Bank made fourteen payments to itself totaling $22,718.86 from *631funds presented to the Bank’s tellers by Herzog in the form of personal checks or cash.1 The Bank’s own internal policy required that all funds used for the issuance of “official checks” in an amount in excess of $3,000 first be deposited into an account at the Bank. The Bank also customarily placed a hold on funds from foreign bank checks in order to verify that the accounts on which the checks were drawn contained sufficient funds to cover the checks. Both of these policies were waived in the Bank’s dealings with Gary Herzog and Herzog Brothers.2
Following Gary Herzog’s deposition, Witco filed in the district court a motion to compel payment by the Bank, contending that the Bank “possessed” Herzog Brothers’ funds and that the Bank had a duty to hold those funds for Witco. Finding that Pennsylvania law dictates that interrogatories in aid of execution be treated as though they were a complaint and the garnishee’s answers to the interrogatories as an answer to the complaint (Pa.R.C.P. 3145(a)), and that the parties had conducted discovery in aid of execution, the district court treated Witco’s motion and the Bank’s response as cross-motions for summary judgment, noting that the parties agreed that there existed no genuine issues of material fact. The district court then denied Witco’s motion for summary judgment and granted the Bank’s motion. Ruling on the narrow issue of whether the Bank came into possession, as that term is defined in Pa.R.C.P. 3101(b), of the Herzog Brothers’ property during the cashier’s check transactions, the district court likened the transactions to any sales transaction where the purchaser tenders full payment at the time of the sale. Because Gary Herzog never deposited his cash or personal checks in the Bank as part of the cashier’s check *632purchases, the court found as a matter of law that the Bank never came into possession of Herzog Brothers’ property. Witco appealed to the Third Circuit, which determined that the district court’s decision raised significant questions of Pennsylvania law not previously decided by this Court and, in turn, certified those questions to this Court for resolution.
The first question for this Court’s consideration is whether a drawee bank obtains “possession” of any property, as defined by Pa.R.C.P. 3101, of a customer who physically provides the drawee bank’s teller with cash and checks, in exchange for the issuance of a cashier’s check, when those funds are never deposited into the customer’s account at the drawee bank. Our inquiry necessarily begins with Rule 3101(b) which, for purposes of “enforcement of money judgments for the payment of money,” defines a garnishee as follows:
(b) Any person may be a garnishee and shall be deemed to have possession of property of the defendant if the person
(1) owes a debt to the defendant;
(2) has property of the defendant in his or her custody, possession or control; ...
(3) holds as fiduciary property in which the defendant has an interest;
(4) holds the legal title to property of the defendant whether or not in fraud of creditors; or
(5) owns or possesses real property subject to a mortgage, judgment or other lien in which [the] defendant has an interest.
Id. For purposes of this Rule, “ ‘defendant’ means any party against whom a judgment has been entered.” Id., Rule 3101(a).
The Rule does not define “possession” for purposes of garnishment, and neither the parties nor the district court cite to any authority from Pennsylvania or any other jurisdiction bearing on the issue presented here.3 Nor did our research *633uncover any case law directly on point. The Bank argues that this Court should adopt the district court’s reasoning that the cashier’s check purchases amounted to nothing more than sales transactions in which Herzog Brothers purchased a series of checks from the Bank, but the Bank did not acquire custody or control of any Herzog Brothers property. Witco, on the other hand, urges a plain language interpretation of Rule 3101, conferring on the word “possession” its common and approved usage in accordance with Pa.R.C.P. 103(a) (‘Words and phrases shall be construed according to rules of grammar and according to their common and approved usage”). We agree with Witco that a plain language approach is required in this instance.
Rule 3101(b) unambiguously provides that a garnishee is deemed to be in possession of property of the defendant if the garnishee “has property of the defendant in his or her custody, possession or control.” Black’s Law Dictionary (8th Ed. 2004) defines possession as: “The fact of having or holding property in one’s power; the exercise of dominion over property.” Here, when Herzog Brothers purchased 131 cashiers’ checks from the Bank, the Bank came into physical possession of the personal checks and cash proffered by Gary Herzog.4 The Bank then had the power to control Herzog Brothers’ access to those funds and the manner in which the funds were disbursed. Indeed, pursuant to its ordinary business policies, the Bank had the power to hold the checks Gary Herzog presented until it determined that sufficient funds existed in the banks upon which the checks were drawn before making the funds available to Herzog Brothers. In addition, the Bank’s internal policy provided that funds for a cashier’s check in excess of $3,000 were to be deposited into an account with the Bank prior to issuance of the cashier’s check. That the Bank chose in the case of this particular customer/ judgment *634debtor not to follow its usual practices, and thereby declined to hold the checks or require that the funds be deposited in a Herzog Brothers’ account, does not negate that the Bank had those powers over the funds—powers which derived from the fact that they were in possession of the funds, if only for a brief time. Thus, applying the common and approved definition of the term “possession,” we conclude that the Bank was in possession of the checks and cash once Herzog handed them over to the Bank’s tellers, for purposes of Rule 3101(b), notwithstanding that Herzog did not formally deposit the funds into Herzog Brothers’ account with the Bank.
Having found that the Bank indeed had possession of Herzog Brothers’ property, we turn to the second certified question—whether a garnishee bank, which receives “possession” of the property of a judgment debtor after being served with a writ of execution, has a duty under Pa.R.C.P. 3111(c) “restraining [it] from paying any debt” to that judgment debtor in exchange for that property, even if that “debt” arises during a transaction with a brief duration akin to that of a sales transaction. Rule 3111(c) states:
(c) Service of the writ upon the garnishee shall also subject the garnishee to the mandate and injunctive orders of the writ restraining the garnishee from paying any debt to or for the account of the defendant and from delivering any property of the defendant which may be attached under these rules to anyone except the sheriff or otherwise disposing thereof until further order of the court or discontinuance or termination of the attachment.
Witco argues that, by its plain language, Rule 3111(c) imposes a duty upon the garnishee to restrain from paying any debt to or on behalf of the judgment debtor, and that the duration of the transaction is irrelevant. Because “debt” is not defined in the Rules of Civil Procedure, Witco urges that “debt” be defined according to its common and approved usage. See Pa.R.C.P. 103(a). Witco then cites the Superior Court’s decision in Prevish v. Northwest Medical Center Oil City Campus, 692 A.2d 192 (Pa.Super.1997) aff'd, 553 Pa. 73, 717 A.2d 1023 (1998) (per curiam), where that court endeav*635ored to define “debt” as it relates to the Probate Code, 20 Pa.C.S. § 101 et seq. Because “debt” is not defined in the definitional section of the Probate Code, the court looked to the default statutory definitions found in the Statutory Construction Act, 1 Pa.C.S. § 1501 et seq., which define “debtor” as “[o]ne who owes to another the performance of an obligation.” 1 Pa.C.S. § 1991. Extrapolating from the statutory definition of “debtor,” the court defined debt as “an obligation the performance of which is owed to another.” Prevish, 692 A.2d at 199.
Witco argues that, applying this logical definition of debt to the controversy at hand, upon receipt of the cash or checks from Gary Herzog, a performance obligation arose whereby the Bank was obliged to perform some act with regards to Herzog Brothers funds. In this case, the Bank fulfilled that obligation by issuing the cashiers checks. The act of issuing the cashiers checks, according to Witco, constituted the payment of a debt to Herzog Brothers, an act prohibited by Rule 3111(c). In the alternative, Witco argues that the issuance of the cashiers checks to third parties identified by Gary Herzog amounted to a payment of debts for the account of Herzog Brothers in violation of Rule 3111(c).
As to the brief duration of the transactions and the Bank’s possession of Herzog Brothers’ funds, Witco contends that duration is not a relevant factor, pointing in support to In re Southwestern Glass Co., 332 F.3d 513 (8th Cir.2003). There, the Eighth Circuit Court of Appeals discussed the obligations of a garnishee bank after it has been served with a writ of garnishment. Subsequent to being served with a writ garnishment, the garnishee bank in that case continued to honor checks drawn on a loan manager account belonging to the judgment debtor where the account maintained a zero balance and was funded through a line of credit the debtor maintained with the bank. Whenever checks drawn on the account were presented to the bank, the bank immediately funded the account in the amount of the check presented and then disbursed the funds to the payee. The transfer of funds from the line of credit to the loan manager account and then *636payment to the payee were instantaneous; the funds remained in the loan manager account for only a brief time. On these facts, the bank maintained that it never had possession of funds belonging to the judgment debtor due to the brief duration of the transactions. The Eight Circuit disagreed, holding that: “the proceeds from [the debtorj’s line of credit transferred into the loan manager account became money or credits belonging to [the debtor] for the brief period of time between the transfer of the proceeds to the account and disbursement of the proceeds to the payee.” . Id. at 518.
The Bank counters that Herzog Brothers’ ongoing purchases of cashier’s checks were merely over-the-counter exchanges in which the Bank served as a financial intermediary. In the Bank’s view, Gary Herzog provided the funds to the Bank’s tellers in exchange for the cashier’s checks without any intention of depositing the funds or of giving the funds to the Bank to hold. Nor did Herzog Brothers intend that the funds be used to pay a debt on its behalf. The Bank argues that Witco’s characterization of these exchanges of funds for cashier’s check as giving rise to a debt is untenable and not supported by authority. Further, the Bank submits that this characterization would turn every purchase and sale transaction into a debt subject to garnishment. The Bank also argues that, had it acted as Witco claims it should have by seizing the cash and checks Gary Herzog presented to the Bank’s tellers and turning those funds over to Witco, its conduct would have been actionable, unethical, legally and constitutionally questionable and commercially unreasonable. Finally, the Bank distinguishes Southwestern Glass on the basis that the funds in question here were never actually deposited in an account belonging to Herzog Brothers.
We do not accept the Bank’s characterization of the cashier’s check transactions with its judgment debtor customer in this case as akin to other innocent purchases and sales transactions. What obviously separates the situation sub judice from other everyday sales transactions is that the Bank maintained a banking relationship with Herzog Brothers and had been served with a writ of execution precisely because of *637that banking relationship. The nature of the relationship renders the Bank’s conduct in waiving its usual policy and issuing no-delay cashier’s checks in exchange for cash and personal checks tendered by its apparently-preferred customer suspect. Even if it was not the Bank’s specific intent, it appears that the Bank engaged with Herzog Brothers in transactions patently calculated to thwart the garnishment process. It is undisputed that the Bank was aware of the judgment against Herzog Brothers and had been served with a writ of execution. Nevertheless, over the course of thirteen months, the Bank processed more than $6 million in cash and checks exchanged for at least 131 of the Bank’s cashier’s checks—without any consideration for its lawfully imposed duty as garnishee. In light of these facts, we reject the notion that the conduct at issue amounted to a series of simple, innocent sales transactions having nothing to do with the Bank’s relationship with its customer as an account holder whose account was subject to garnishment.
We should note, however, that we do not accept Witco’s broad argument that the presentation of the cash and checks to the Bank’s tellers gave rise to a debt owed by the Bank to Herzog Brothers. This strained interpretation of the word “debt” could conceivably capture any wholesale or retail sales transaction. In any case, there is no need to concern ourselves with the issue because it seems crystal clear that, when the Bank converted Herzog Brothers’ cash and checks into cashier’s checks and made those cashier’s checks payable to third parties or to the Bank itself at Herzog Brothers’ direction, the Bank was paying debts on account of Herzog Brothers. The Bank’s conduct implicates and runs afoul of Rule 3111(c). This is particularly true in the case of checks used by Herzog Brothers to fund the cashier’s checks where the checks were drawn on foreign banks. In those instances, the Bank issued the cashier’s checks with no knowledge of whether sufficient funds existed to cover the checks in the foreign banks; therefore, the Bank was essentially advancing bank funds to Herzog Brothers and then using those funds to pay debts on behalf of Herzog Brothers.
*638We agree with Witco, however, that the Eighth Circuit’s reasoning in Southwestern Glass, to the effect that the duration of the transaction is not pertinent, is persuasive and should apply to similar situations arising under Pennsylvania law. Although the funds in Southwestern Glass were actually deposited into an account managed by the debtor, the deposit and subsequent disbursement of the funds took place within a very brief time period. In fact, the deposits were made at the moment when a check drawn on the account was presented to the bank. Therefore, the deposit and disbursal were practically simultaneous, much like the transactions at issue here. The Bank is correct that the funds in this case were never technically deposited into Herzog Brothers’ account at the Bank. However, the Bank did take possession of Herzog Brothers’ property, albeit briefly, and, like the bank in Southwestern Glass, this brief possession obligated the Bank to hold the funds for Witco in accordance with Rule 3111(c). Thus, in answer to the second question posed by the Third Circuit, we hold that the duty imposed by Rule 3111(c) to refrain from paying debts to or on account of the judgment debtor is not negated by a transaction that is brief in duration.
Turning to the third certified question, this Court is asked to consider whether the public policy underlying Pennsylvania garnishment law requires a garnishee bank, on notice of a judgment order against a depositor by a Writ of Execution and whose accounts are thereby held, to refrain from engaging in transactions with that judgment debtor which permit the judgment debtor to avoid the garnishment of its assets, and thereby the debtor’s obligation to pay the judgment creditor, to the financial benefit of the garnishee bank.
The Bank argues that Pennsylvania garnishment law does not require a financial institution to join in a judgment creditor’s hunt for assets or in the creditor’s efforts to drive a judgment debtor out of business.5 The Bank further asserts *639that garnishment rules are not designed “to relegate a judgment debtor to a financial leper colony” until payment of the judgment. Brief of Appellee at 23. The Bank posits that, in this case, Herzog Brothers could have purchased money orders at a convenience store and accomplished the same result with no questions arising as to whether the convenience store should have issued the money orders and that requiring the convenience store to cease all contact, including sales transactions, goes beyond the purpose of the garnishment rules. The Bank thus posits that its activities in this case are indistinguishable from those of a convenience store selling money orders to anonymous customers. Therefore, in the Bank’s view, neither the garnishment rules themselves nor public policy should be construed to prohibit the sales of cashier’s checks that occurred here.
Witco responds that public policy should prohibit actions which, whether so intended or not, appear designed to avoid a valid writ of execution. Witco argues that the Bank’s conduct clearly violated both the letter and spirit of the garnishment rules, ultimately permitting Herzog Brothers to avoid execution of the lawfully obtained judgment against it. The Bank here clearly provided Herzog Brothers with all the benefits of a bank account while assisting Herzog Brothers in avoiding the seizure of their assets, which was required pursuant to the writ of execution. Witco asserts that if this Court permits this type of activity in garnishment cases, the ability of creditors to collect judgments will be severely diminished. Witco is correct.
The Bank in this case was not a convenience store engaged in the innocent sale of money orders to a walk-in customer with whom it had no prior relationship. To argue that the Bank had no more obligation to Witco than a convenience *640store would have to a walk-in customer is fatuous on the facts of this case. Again, Herzog Brothers and the Bank enjoyed an ongoing commercial banking relationship that predated Witco’s garnishment proceedings. The Bank was served with a writ of execution relative to Herzog Brothers precisely because of its status as Herzog Brothers’ banker. Therefore, the Bank was fully aware of the judgment against Herzog Brothers and of its obligation to safeguard Herzog Brothers’ assets currently in the Bank’s possession and those that subsequently came into the Bank’s possession. The Bank failed to do so, instead acquiescing in a course of conduct that treated Herzog Brothers differently than other customers, and essentially allowed Herzog Brothers to exchange its assets without exposing them to garnishment. The Bank thus permitted Herzog Brothers to continue a banking relationship without requiring them to actually deposit money into any of Herzog Brothers’ garnished accounts. This arrangement benefited the Bank as well as Herzog Brothers, to the tune of over $22,000 in little more than a year. See note 1 supra.
It is essential to remember that this third question arises under the rubric of public policy. In assessing and weighing such considerations, this Court will not turn a blind eye to the obvious effects of the conduct at issue. It is plain that the Bank and Herzog Brothers engaged in an extended course of conduct that permitted Herzog Brothers to avoid garnishment of its assets. Whether it was the Bank’s and/or Herzog Brothers’ deliberate intent to subvert the writ of execution and subsequent garnishment obligation matters less than the fact that such was clearly the result. By using cashier’s checks instead of checks drawn on its own accounts, Herzog Brothers successfully processed more than $6 million dollars of its funds and used those funds to pay its obligations to creditors other than Witco without depositing one penny of those funds into its accounts with the Bank. The Bank permitted this conduct and even derived its own financial benefit, making the Bank a player in this activity, not an innocent bystander. Were this Court to sanction this type of conduct on grounds of “public policy,” we would, as Witco argues, be *641placing a stranglehold on judgment creditors in their efforts to collect judgments. In addition, we would be giving carte blanche to judgment debtors who are sharp enough in their business dealings to devise creative methods to avoid collection of valid judgments obtained lawfully against them. Such a course is clearly not within the spirit or intent of the. garnishment rules, and we will not allow conduct that so eviscerates that spirit and intent, under the guise of enforcing some other public policy.
Thus, our answer to the Third Circuit’s final certified question is simply this: the public policy of Pennsylvania prohibits a garnishee bank with notice of a judgment order from engaging in transactions with the judgment debtor that it knows or should know will facilitate the judgment debtor in attempts to avoid the lawful garnishment of its assets.
Questions answered. Jurisdiction relinquished.
Chief Justice CAPPY files a dissenting opinion.. The Third Circuit noted that these payments to the Bank appeared to be mostly regular monthly payments in set amounts: $876.20 per month from November 1996 to February 1997, except a December 1996 payment in the amount of $1,314,20; $601.20 per month from March to July 1997, except a June 1997 payment in the amount of $901.90; and one lump sum payment of $15,000 on September 5, 1996.
. The Bank claims that these policies were waived for Herzog Brothers long before the garnishment proceedings began.
. The Bank devotes substantial argument to defining a cashier’s check as a cash equivalent. This argument begs the question presented *633here—whether the Bank had possession of Herzog Brothers' property during the transaction that culminated in the issuance of the cashier’s checks.
. There appears to be no dispute that the personal checks and cash employed by Gary Herzog to buy the bank cashiers' checks represented property belonging to Herzog Brothers.
. Implicit in the Bank’s argument is the suggestion that, had Herzog Brothers been forced to pay Witco the amount of the judgment, Herzog Brothers would not have been able to operate its business. Nothing in the record supports this assertion, and indeed, it appears that the *639assertion is suspect. In little more than a year, the Bank processed more than $6 million of Herzog Brothers’ funds through the issuance of cashier’s checks. Thus, the amount of Witco's judgment ($509,216.52) represents approximately 8% of the funds the Bank processed for its customer in slightly more than one year. Nothing in the record facts supports an assertion that honoring the writ of execution would have driven Herzog Brothers out of business.
