MEMORANDUM OF DECISION
JIM D. PAPPAS, Bankruptcy Judge.Introduction
Plaintiffs, chapter 111 debtor Old Cutters, Inc. (“Old Cutters”), and its creditor Mountain West Bank (“MWB”), commenced these adversary proceedings against Defendant, the City of Hailey (“Hailey”).2 In responding to Plaintiffs’ complaints, and at a March 15, 2012, pretrial conference, Hailey asserted that the Court lacks subject matter jurisdiction to entertain this action. Even if the Court has subject matter jurisdiction, Hailey argued the Court also lacks the constitution*222al authority to enter a final judgment in the adversary proceeding. However, Hai-ley later withdrew its objection to the Court’s exercise of subject matter jurisdiction, and expressly consented to the Court’s entry of a final judgment. Despite doing so, on June 7, in responding to the Court’s order, Hailey again argued that the Court lacks subject matter jurisdiction. Inasmuch as Hailey’s submissions have created a continuing question regarding the existence of this Court’s subject matter jurisdiction and/or its constitutional authority to hear, decide, and enter a final judgment in this action, this Memorandum settles the issue.
Facts3 and Procedural Background
Old Cutters purchased certain real property (the “Property”) in 2003, intending to subdivide and develop it as a residential planned unit development. At that time, the Property was subject to Blaine County ordinances, though it was contiguous to other property located within Hailey’s boundaries. In anticipation of the Property’s development, Old Cutters investigated various options for providing water and sewer services to the proposed development, including annexation of the project into Hailey.
Ultimately, Old Cutters determined to pursue annexation of the Property into Hailey. After a series of public meetings and negotiations between Old Cutters’ and Hailey’s representatives, the parties settled on $3,787,500 as the amount of the annexation fee to be paid by Old Cutters to Hailey, and executed an Annexation, Services and Development Agreement (“Annexation Agreement”). As to the annexation fees, the agreement provides:
The Parties acknowledge and agree that the annexation fee described in this Paragraph 4 are [sic] fair and equitable and that the annexation fees have been agreed upon as consideration for the City providing essential governmental and utility services to the Property and to mitigate the impact on the City of annexation and development of the Property.
Annexation Agreement at ¶4£, Adv. No. 11-8105, Dkt. No. 1-1. Old Cutters and Hailey executed the Annexation Agreement on April 10, 2006.4 See Annexation Agreement, Adv. No. 11-8105, Dkt. No. 1-1.
Old Cutters paid $1,317,000 of the required annexation fees. Hailey, relying upon the Annexation Agreement,5 contends the remaining $2,470,500 in annexation fees are secured by a first-position lien against the Property in Hailey’s favor.
At about the time Old Cutters and Hai-ley executed the Annexation Agreement, Hailey adopted an Inclusionary Community Housing Ordinance (“ICH Ordinance”). Per the ICH Ordinance, every new residential development of five lots or more was required to dedicate twenty percent of its total lots to affordable housing.6 Old Cutters intended to develop a subdivision *223of up to 149 residential units, and the parties documented how Old Cutters would meet the requirements of the ICH Ordinance in their Annexation Agreement. The parties agreed Old Cutters would develop twenty-five community housing units, and indicated:
COMMUNITY HOUSING ORDINANCE. [Old Cutters] hereby waives any right it may have to assert that the City’s Community Housing Ordinance is invalid in whole or in part as it applies to the Subdivision [contemplated by the Annexation Agreement].
Id. at ¶ 11 (bold in original).
Hailey repealed the ICH Ordinance in 2010. However, Old Cutters and Hailey would not amend the Annexation Agreement to remove the community housing requirements.
To finance Old Cutters’ development of the Property, MWB extended $12,000,000 in credit to Old Cutters in December 2006. To secure this loan, Old Cutters executed a mortgage on the Property in favor of MWB. Adv. No. 11-8106, Dkt. No. 1-2. The loan amount was increased to $13,133,000 in 2008, and MWB’s mortgage against the Property was modified accordingly. Id.
Old Cutters filed for chapter 11 relief on August 1, 2011. Bankr. No. 11-41261, Dkt. No. 1. Only three parties have filed claims in Old Cutters’ bankruptcy case. An entity related to Old Cutters, named Old Cutters Investment, LLC, filed an unsecured claim for $8,314,446, based on a “real estate sale.” Claim No. 1-1. MWB filed a claim for $9,227,327.29, based on a “real estate loan” secured by the Property. Claim No. 2-1. And, Hailey filed a claim for $2,579,855.64, based on the Annexation Agreement, secured by “Market Rate Lots.” Claim No. 3-1.
Six days after Hailey filed its claim, Old Cutters commenced an adversary proceeding against Hailey. Adv. No. 11-8105, Dkt. No. 1. Through that adversary proceeding, Old Cutters seeks a determination that “the annexation fee that continues to be demanded by the City is unlawful, that [Old Cutters] does not owe any additional annexation fees to the City, and that the City’s lien on the Property is void.” Complaint at 13, Adv. No. 11-8105, Dkt. No. 1. Old Cutters further seeks a determination that the IHC Ordinance was unlawful, and that Hailey should be permanently enjoined from enforcing the Annexation Agreement’s community housing requirements. Id. at 13-14. Old Cutters bases its argument for such relief on various assertions that Hailey’s actions were “illegal,” and that it violated various, largely unspecified,7 state and federal laws. Id.
MWB initiated its own adversary proceeding against Hailey four days after Old Cutters filed its complaint. Adv. No. 11-8106, Dkt. No. 1. Through that action, MWB sought a determination that, because Hailey relied on the language of the Annexation Agreement as providing the basis for its lien against the Property, and because the Annexation Agreement describes the portion of the Property securing its interest in the annexation fees as the “Market Rate Lots,” that description is insufficient to satisfy the statute of frauds and Idaho’s statutes for establishing a mortgage in property. See id. at 3-4. Thus, MWB argued, the lien purportedly created by the Annexation Agreement is unenforceable, and Hailey’s lien should be avoided. Id. at 4. MWB also used its adversary proceeding to assert its objec*224tion to Hailey’s proof of claim. Id. In doing so, MWB echoed many of the arguments from Old Cutters’ complaint, including that the annexation fee was arbitrary and capricious and exceeded Hailey’s police power; that the fee was an “unauthorized tax;” that it was a taking of property in violation of the state and federal constitutions; that it was “illegal;” and that Hai-ley exceeded its statutory authority and violated substantive due process. Id. at 4-5.
Hailey filed answers to Old Cutters’ and MWB’s complaints on January 17 and 19, 2012, respectively. Adv. Dkt. No. 11-8105, Dkt. No. 5; Adv. Dkt. No. 11-8106, Dkt. No. 7. In each of those answers, Hailey raised certain affirmative defenses. Notably, in its answer to Old Cutters’ complaint, Hailey asserted:
This Court, as an Article 1 [sic] Court, does not have the judicial authority to exercise all of the judicial powers of courts of the United States and therefore may not rule on whether the annexation fees imposed are or were arbitrary or capricious, or exceeded the City’s Police Power; constituted an unauthorized tax; amounted to an illegal taking of private property in violation of the Idaho and Federal constitutions; violated the equal protection clause of the 14th Amendment; or was otherwise illegal. Nor can this Court exercise the judicial power of the United States to make the same determination concerning the legality of the community housing requirements. Nor may this Court exercise the judicial powers of the United States to grant injunctive relief on the basis of continuing violations of state and federal law.
Answer at 7-8, Adv. No. 11-8105, Dkt. No. 5. Hailey was more succinct in response to MWB’s complaint:
This Court, as an Article 1 [sic] Court, does not have subject matter jurisdiction to determine the issues raised by Plaintiff in its Complaint, [in its objections to Hailey’s proof of claim], and must decline jurisdiction over the allegations contained in [that portion of its Complaint].
Answer at 4, Adv. No. 11-8106, Dkt. No. 7.
The Court held a consolidated pre-trial conference on March 15, 2012. At the pretrial conference, counsel clarified that Hai-ley questioned the Court’s subject matter jurisdiction over the adversary proceedings as well as the Court’s constitutional authority to enter a final judgment granting the relief requested by Plaintiffs. In response, the Court directed the parties to file briefs regarding the subject matter jurisdiction and constitutional authority issues, with Hailey’s initial briefing deadline set for April 13.
On April 13, rather than file its brief, Hailey filed a Motion to Vacate Briefing Schedule on Bankruptcy Court Subject Matter Jurisdiction. Adv. No. 11-8105, Dkt. No. 12. Hailey urged the Court to vacate the established briefing deadline because it had moved to dismiss Old Cutters’ bankruptcy case, and had set an evi-dentiary hearing on the motion for April 17. Id. Hailey asserted that, depending on the outcome of that hearing, the need for additional briefing may be moot. Id. Old Cutters’ bankruptcy case was not dismissed, however, and the Court modified the briefing schedule. Adv. No. 11-8105, Dkt. No. 19. Hailey was given until May 11 to submit a brief “concerning the subject matter jurisdiction of [the Court] over [the adversary proceedings], or concerning the [C]ourt’s constitutional power to enter a final judgment in [the adversary proceedings].” Id.
This time, instead of filing a brief, Hai-ley filed a Notice of Withdrawal of Defense *225Re Subject Matter Jurisdiction on May 10, Adv. No. 11-8105, Dkt. No. 22, and “withdrew” the defense on May 15, 2012, Adv. No. 11-8105, Dkt. No. 23. In doing so, as near as the Court can tell, Hailey intended to strike those portions of its answers to Plaintiffs’ complaints in which it asserted that this Court lacks subject matter jurisdiction over Plaintiffs’ adversary proceedings. Adv. No. 11-8105, Dkt. No. 23. At the same time, Hailey did not clearly address its position concerning whether the Court has constitutional authority to enter a final judgment in this action, nor did it expressly consent to the Court’s authority to enter such judgment. See id.
Unsatisfied that Hailey’s withdrawal settled the issue of the Court’s constitutional authority to enter a final judgment, the Court entered yet another, supplemental order requesting additional briefing on that issue. Adv. No. 11-8105, Dkt. No. 24. The day prior to its briefing deadline, Hai-ley filed a Response to Supplemental Order Establishing Briefing Schedule Regarding the Court’s Authority to Enter a Final Judgment. Adv. No. 11-8105, Dkt. No. 28. Remarkably, though, rather than focus on the issue of the Court’s constitutional authority, the bulk of Hailey’s “response” is an argument against the Court’s subject matter jurisdiction.8 In the end, Hailey urged the Court to “rule that it does not have subject matter jurisdiction to decide the constitutional law issues which the Plaintiffs raise.” Hailey’s Response at 2, Adv. No. 11-8105, Dkt. No. 28. At the same time, in its lone paragraph addressing the Court’s constitutional authority to enter a final judgment, Hailey provided that, if the Court finds it has subject matter jurisdiction to hear and decide this action, “then the City of Hailey will, and does hereby, consent to this Court’s entry of a final judgment.” Id. at 8.
Hailey’s “on again-off again” approach to the Court’s desire to resolve any jurisdictional or constitutional issues in this action is unfortunate. However, to the extent there may be any remaining questions about whether the Court can and should properly adjudicate the issues in these actions, this Memorandum is intended to finally resolve them.
Discussion
While Hailey initially objected to this Court’s subject matter jurisdiction and its constitutional authority to enter a final judgment, the Court concludes that both of those objections have been resolved.
Regarding the Court’s subject matter jurisdiction, Hailey “admitted] that [the Old Cutters] Adversary Proceeding may be ‘related to’ the bankruptcy proceeding” when it filed its answer to Old Cutters’ complaint. Hailey’s Answer at ¶ 6, Adv. Dkt. 11-8105, Dkt. No. 5. Hailey also formally withdrew its subject matter jurisdiction objections in both adversary proceedings on May 15, 2012. Adv. No. 11-8105, Dkt. No. 23. However, in the event that Hailey may harbor any residual jurisdictional objections, the Court herein concludes it indeed possesses the requisite subject matter jurisdiction to hear and decide both adversary proceedings.
Congress conferred “original but not exclusive jurisdiction of all civil proceedings *226arising under title 11, or arising in or related to cases under title 11” on the district courts. 28 U.S.C. § 1334(b). Moreover, Congress allows district courts to refer “any or all cases under title 11 and any or all proceedings arising under title 11 or arising in or related to a case under title 11” to bankruptcy judges. 28 U.S.C. § 157(a). In Idaho, the District Court has “refer[red] to the Bankruptcy Judges of this District all cases under Title 11 and all proceedings arising under Title 11 or arising in or related to cases under Title 11.” Order Referring Bankruptcy Cases and Proceedings to Bankruptcy Judges, Third Amended General Order No. 38 (D.Idaho 1995).
“ ‘Arising under’ and ‘arising in’ are terms of art.” Eastport Assocs. v. City of Los Angeles (In re Eastport Assocs.), 935 F.2d 1071, 1076 (9th Cir.1991). Proceedings arising under title 11 are those that are created or determined by a statutory provision of title 11. Id. (quoting Wood v. Wood (In re Wood), 825 F.2d 90, 96-97 (5th Cir.1987)). “ ‘[A]rising in’ proceedings are those that are not based on any right expressly created by title 11, but nevertheless, would have no existence outside of the bankruptcy.” Id. Included in the scope of “arising in” proceedings are administrative matters and determinations of the validity, extent, or priority of liens. See id.; Nelson v. Welch (In re Repository Techs., Inc.), 601 F.3d 710, 719 (7th Cir. 2010).
Some proceedings that do not invoke a substantive right created by federal bankruptcy law, and that could exist outside of bankruptcy, also fall within bankruptcy courts’ jurisdiction as “related to” proceedings. In re Eastport Assocs., 935 F.2d at 1076-77. In vesting jurisdiction over matters “related to” bankruptcy cases in the district courts, and in allowing those district courts to refer such matters to bankruptcy courts, “Congress intended to grant comprehensive jurisdiction to the bankruptcy courts so that they might deal efficiently and expeditiously with all matters connected with the bankruptcy estate.” Celotex Corp. v. Edwards, 514 U.S. 300, 308, 115 S.Ct. 1493, 131 L.Ed.2d 403 (1995) (quoting Pacor, Inc. v. Higgins, 743 F.2d 984, 994 (3d Cir.1984)). To determine the existence of related to jurisdiction in a given proceeding, the test adopted by the majority of the Circuit Courts of Appeals, and approved of by the Supreme Court, is
whether the outcome of that proceeding could conceivably have any effect on the estate being administered in bankruptcy.... Thus, the proceeding need not necessarily be against the debtor or against the debtor’s property. An action is related to bankruptcy if the outcome could alter the debtor’s rights, liabilities, options, or freedom of action (either positively or negatively) and which in any way impacts upon the handling and administration of the bankruptcy estate.
Celotex Corp., 514 U.S. at 308 n., 115 S.Ct. 14936 (quoting Pacor, Inc., 743 F.2d at 994) (emphasis in original); see also Fietz v. Great W. Savs. (In re Fietz), 852 F.2d 455, 457 (9th Cir.1988) (adopting the Pacor test in the Ninth Circuit).
Of particular import here is the fact that Hailey filed a proof of claim in Old Cutters’ bankruptcy case and asserted a lien on Old Cutters’ Property. Old Cutters’ adversary complaint seeks a determination that it does not owe Hailey additional annexation fees, that Hailey’s lien on Old Cutters’ property is invalid, and that Old Cutters is not required to comply with the community housing requirements of its annexation agreement. Because it seeks to determine the validity of Hailey’s proof of claim, and the validity, extent, and pri*227ority of Hailey’s lien on the Property, Old Cutters’ adversary proceeding “arises in” its bankruptcy, and the Court has subject matter jurisdiction over the proceeding.
MWB’s adversary complaint likewise seeks a determination that Hailey’s annexation agreement with Old Cutters is unenforceable, and, as a result, that Hailey’s lien against Old Cutters’ property is void. In addition, MWB objects to allowance of Hailey’s proof of claim in the bankruptcy case. In other words, via its complaint, MWB challenges the validity of Hailey’s interest in property of the bankruptcy estate, and invokes the claims allowance process. Moreover, the issues raised by MWB’s complaint are obviously intertwined with those implicated in Old Cutters’ litigation with Hailey. Clearly, given the size of Hailey’s alleged claim in Old Cutters’ bankruptcy and its purported secured status, the outcome of these adversary proceedings will significantly impact Old Cutters’ ability to reorganize; will impact Old Cutters’ rights, liabilities, and options; and will influence the Court’s handling and administration of Old Cutters’ bankruptcy case. Thus, MWB’s claims also “arise in” Old Cutters’ bankruptcy case, and the Court has subject matter jurisdiction in that adversary proceeding as well.
As to the Court’s authority to enter a final judgment, bankruptcy courts may enter judgments in “all core proceedings arising under title 11, or arising in a case under title 11.” 28 U.S.C. § 157(b)(1). “Core proceedings” include: “matters concerning the administration of the estate,” 28 U.S.C. § 157(b)(2)(A); “allowance or disallowance of claims against the estate,” 28 U.S.C. § 157(b)(2)(B); “determinations of the validity, extent, or priority of liens,” 28 U.S.C. § 157(b)(2)(E); and “proceedings affecting the liquidation of the assets of the estate or the adjustment of the debtor-creditor ... relationship,” 28 U.S.C. § 157(b)(2)(0). Where such a proceeding also “derives from [the] federal [bankruptcy] regulatory scheme,” the bankruptcy court has constitutional authority to enter a judgment in the proceeding. See Stern v. Marshall, — U.S.-, 131 S.Ct. 2594, 2613-15, 180 L.Ed.2d 475 (2011) (discussing “public rights” cases that Congress can constitutionally assign to “legislative” courts for resolution). These adversary proceedings are core proceedings pursuant to 28 U.S.C. § 157(b)(2)(A), (B), (K), and/or (0). The Court is statutorily authorized to enter a final judgment in the adversary proceedings, and also has the constitutional authority to do so.
Even if the adversary proceedings were merely “related to” Old Cutters’ bankruptcy case, which at a minimum, no doubt, these adversary proceedings are, this Court has statutory and constitutional authority to enter a final judgment “with the consent of all the parties to the proceeding.” See 28 U.S.C. § 157(c)(2); cf. Stern, 131 S.Ct. at 2614-15 (finding that the bankruptcy court did not have constitutional authority to enter a final judgment because one of the parties “did not truly consent to resolution of [the] claim in the bankruptcy court proceedings”). Hailey has, through its Response to the Court’s Supplemental Order, expressly consented to the Court’s entry of final judgments in the adversary proceedings. Plaintiffs consented to the Court’s authority to enter final judgment at the March 15 pre-trial conference. Because all of the parties have consented to the Court’s entry of final judgments, the issue of the Court’s constitutional authority to enter final judgments has also been resolved.
Conclusion
The Court has subject matter jurisdiction over both Old Cutters’ and MWB’s *228adversary proceedings. It also has the constitutional authority to enter final judgments in each proceeding.
The Court will schedule a continued pretrial conference in these actions to discuss establishment of case management deadlines and a trial date.

. In spite of the Court's clear instructions regarding briefing on the issue of its constitutional authority, and although Hailey acknowledged that it “had intended to, and did, withdraw its objection to subject matter jurisdiction/' Hailey seemed to regard the Court’s Supplemental Order as a sua sponte invitation to revisit its subject matter jurisdiction. Hai-ley's Response at 2, Adv. No. 11-8105, Dkt. No. 28 (“The City of Hailey understands that this Court must determine its subject matter jurisdiction, even in the absence of a challenge from this Defendant.”).
