OPINION AND ORDER
KENNETH M. KARAS, District Judge.
Plaintiff, Dynegy Danskammer, L.L.C. (“Danskammer”), brings this suit against Peabody COALTRADE International Ltd. (“Peabody”) alleging breach of contract for delaying delivery or failing to deliver coal shipments at various times from 2008 to 2011. Plaintiff Danskammer filed a Chapter 11 petition on November 7, 2011. On July 24, 2012, Defendant Peabody moved to withdraw the reference to the bankruptcy court for the breach of contract claim under 28 U.S.C. § 157(d). (Dkt. No. 1.) For the reasons stated herein, Peabody’s Motion to Withdraw the Reference to bankruptcy court is granted.
I. Background
The following facts, drawn from Danskammer’s Complaint, are assumed to be true for purposes of deciding the instant Motion. On January 1, 2008, Peabody and Danskammer entered into a Contract for Sale and Purchase of Guasare Steam Coal (the “Contract”). (Compl. ¶ 8.) Under the Contract, Peabody agreed to sell and deliver, and Danskammer agreed to purchase and receive, the coal. (Id.) On November 7, 2011, Danskammer filed its Chapter 11 petition. Danskammer alleges that Peabody breached the Contract by “failfing] to timely and completely perform its obligations under the agreement, repeatedly delaying coal shipments or declaring force majeure,” (id. ¶ 13), and points to a delay in late 2008 and failures to deliver in February 2009, April 2009, March 2010, and November 2011, (id. ¶ 13-33). Based on these events, Danskammer pleads two causes of actions: (1) breach of contract, [528]*528and in the alternative, (2) an ongoing anticipatory repudiation of the Contract. (Id. ¶¶ 34-57.) Danskammer claims damages including demurrage charges, dead freight charges, and other incidental and consequential damages. (Id. at 15-16.)
Danskammer filed its Debtor’s Complaint against Peabody for breach of contract on June 4, 2012 in bankruptcy court.1 On July 24, 2012, Peabody filed this Motion to Withdraw the Reference to the bankruptcy court. (Dkt. No. 1.)
II. Discussion
A. Legal Standard
1. Jurisdiction and Adjudicative Power of the Bankruptcy Court
With certain exceptions not relevant here, district courts have original jurisdiction over all civil proceedings “arising under” or “related to” title 11. See 28 U.S.C. § 1334. Pursuant to 28 U.S.C. § 157, district courts may refer “all cases under title 11 and all core proceedings arising under title 11” to the district’s bankruptcy court. 28 U.S.C. § 157(b)(1). Section 157(b)(2) provides a non-exclusive list of proceedings designated as “core.” Id. § 157(b)(2). Until recently, the bankruptcy court’s role depended on whether the proceeding was “core” or “non-core.” With respect to core proceedings, the bankruptcy court could issue a final determination, but with respect to non-core proceedings, it was permitted only to “submit proposed findings of fact and conclusions of law to the district court,” which were then subject to de novo review in the district court. 28 U.S.C. § 157(c); see Cent. Vt. Pub. Serv. Corp. v. Herbert, 341 F.3d 186, 189-91 (2d Cir.2003) (explaining the role of bankruptcy courts in core and non-core proceedings).
In Stem v. Marshall, _ U.S. _, 131 S.Ct. 2594, 180 L.Ed.2d 475 (2011), the Supreme Court altered this framework by holding that the constitutional grant of judicial power to Article III courts, not the statutory designation of “core” or “non-core,” determines whether a bankruptcy judge may issue a final determination. See also Adelphia Recovery Trust v. FLP Grp., Inc., No. 11-CV-6847, 2012 WL 264180, at *2 (S.D.N.Y. Jan. 30, 2012) (explaining Stem’s holding that “Congress’s delineation of core matters in section 1572(b)(2) overstepped constitutional boundaries ... when it allowed bankruptcy courts ‘to enter a final judgment on a state law counterclaim’ ” (quoting Stern, 131 S.Ct. at 2620)); Dev. Specialists, Inc. v. Akin Gump Strauss Hauer & Feld LLP, 462 B.R. 457, 464 (S.D.N.Y.2011) (noting that after Stem, “identifying a claim as ‘core’ or ‘non-core’ under the bankruptcy law does not necessarily determine whether a bankruptcy court is constitutionally empowered to finally adjudicate the matter”). In holding that Article III did not permit a bankruptcy court to adjudicate finally the state law counterclaim at issue in Stem, the Supreme Court considered: (1) whether the counterclaim involved a public or private right; (2) whether the process of adjudicating the creditor’s proof of claim would resolve the counterclaim; and (3) whether the parties consented to final adjudication by the bankruptcy court. 131 S.Ct. at 2608, 2614, 2617.
2. Withdrawal of Bankruptcy Reference
Pursuant to 28 U.S.C. § 157(d), a “district court may withdraw, in whole or in part, any case or proceeding referred under this section ... for cause shown.” [529]*529Prior to Stem, the Second Circuit held in In re Orion Pictures Corp., 4 F.3d 1095, 1101 (1993), that cause for withdrawal should be evaluated based on five factors: “whether the claim or proceeding is core or non-core, whether it is legal or equitable, and considerations of efficiency, prevention of forum shopping, and uniformity in the administration of bankruptcy law.” The Orion court emphasized that “[a] district court considering whether to withdraw the reference should first evaluate whether the claim is core or non-core, since it is upon this issue that questions of efficiency and uniformity will turn.” Id. The Orion court further reasoned that “the fact that a bankruptcy court’s determination on non-core matters is subject to de novo review by the district court could lead the latter to conclude that in a given case unnecessary costs could be avoided by a single proceeding in the district court.” Id.
Following the Supreme Court’s holding in Stem, courts in this district have taken different approaches in adapting the Orion factors to Stem’s holding. Some courts have modified the first prong of Orion (whether a proceeding is core or non-core) and considered whether the bankruptcy court has constitutional authority to finally adjudicate the matter under Stem. See In re Arbco Capital Mgmt., LLP, 479 B.R. 254, 262 (S.D.N.Y.2012) (“This Court concludes, as have others in this district, that the relevant inquiry under the first prong of the Orion test is not whether a matter is core or non-core, but whether the bankruptcy court has the authority to finally adjudicate the matter.”); In re Lyondell Chem. Co., 467 B.R. 712, 719 (S.D.N.Y.2012) (“Under Stem, it is not the core/non-core distinction but Article III that determines the bankruptcy court’s adjudicative authority. Thus, a district court ... must first determine whether or not the bankruptcy court has constitutional authority to enter final judgment on the claim.... To the extent the core/non-core distinction held a privileged position among the Orion factors before Stem, this is no longer the case.”); In re Levine, No. 11-CV-9101, 2012 WL 310944, at *2-3 (S.D.N.Y. Feb. 1, 2012) (applying Stem’s public rights doctrine to the core/non-core Orion factor); Dev. Specialists, Inc., 462 B.R. at 471-72 (modifying Orion’s core/non-core factor to account for final adjudicative authority as determined by Stem); see also Picard v. Avellino, 469 B.R. 408, 413 n. 3 (S.D.N.Y.2012) (acknowledging Stem’s impact on the analysis of judicial efficiency set out in the Orion factors).
A second approach retains the original Orion factors and adds Stem’s evaluation of the bankruptcy court’s constitutional authority to make a final determination as a separate inquiry. See Adelphia Recovery Trust, 2012 WL 264180, at *3 (“After Stem, a court’s consideration of a motion to withdraw reference to bankruptcy court should — in addition to the Orion factors— include consideration of: whether the claims at issue involve a public or private right; whether the claims will be resolved in ruling on a creditor’s proof of claim, if any; and whether the parties consent to final adjudication by a non-Article III tribunal.”); see also Madison Bentley Assocs. v. Bentley Manhattan Inc., LLC, 474 B.R. 430, 435 (S.D.N.Y.2012) (same).
Finally, some district courts have continued to apply the Orion test as originally conceived with no modification in light of the Stern holding. See Extended Stay, Inc. v. Blackstone Grp., 466 B.R. 188, 204 (S.D.N.Y.2011) (“As an initial matter, there is nothing in Stem to suggest that the statutory distinction between core claims and non-core claims is an inappropriate consideration when analyzing permissive withdrawal under section 157(d).”); see also Coudert Bros. v. Peabody Energy Corp., No. 11-CV-4949, 2011 WL 7678683, [530]*530at *3-5 (S.D.N.Y. Sept. 23, 2011) (granting motion to withdraw the reference with respect to non-core claims).
After considering these approaches, this Court concludes that the first of the Orion factors, originally the statutory core/non-core distinction, should include the question of whether the bankruptcy court has constitutional authority to enter a final decision under Stem. The Orion court reasoned that the core/non-core distinction was particularly relevant for efficiency considerations, because if the matter was core, a bankruptcy court could issue a final determination, whereas if the matter was non-core, it would be subject to de novo review by the district court. See Orion, 4 F.3d at 1101. But because the core/non-core determination is no longer dispositive of a bankruptcy court’s authority to enter a final determination, it is no longer “upon this issue that questions of efficiency and uniformity will turn.” Id. Instead, following Stem, the question of whether the bankruptcy court may finally determine a proceeding or whether the bankruptcy court’s proposals must be reviewed de novo by a district court is governed by Article III. See Stern, 131 S.Ct. at 2608. Thus, this Court joins the other courts that have applied a modified analysis of the core/non-core factor under Orion to account for the Article III requirements and exceptions articulated in Stern.
B. Analysis
The Court now considers each of the five Orion factors, as modified by Stem: whether the bankruptcy court has final adjudicative authority over the claim; whether the claim is legal or equitable; and considerations of efficiency, prevention of forum shopping, and uniformity in the administration of bankruptcy law.
1. The Bankruptcy Court’s Final Adjudicative Authority
As discussed above, the first inquiry is whether the bankruptcy court has final adjudicative authority over the claim under Stem’s constitutional analysis. The Stem Court explained that Article III protects liberty “through its role in implementing the separation of powers” and “by specifying the defining characteristics of Article III judges.” 131 S.Ct. at 2609. Therefore, “in general, Congress may not ‘withdraw from [Article III] judicial cognizance any matter which, from its nature, is the subject of a suit at the common law, or in equity, or admiralty.’ ” Id. (quoting Murray’s Lessee v. Hoboken Land & Improvement Co., 59 U.S. 272, 284, 18 How. 272, 15 L.Ed. 372 (1856)). In other words, only Article III courts may make final determinations in common law, equity, and admiralty suits. See id. Consistent with this principle, the Supreme Court set forth three instances where a bankruptcy court may adjudicate finally a claim at issue: (1) if the claim involves a public right; (2) if the process of adjudicating the creditor’s proof of claim would resolve a counterclaim; or (3) if the parties consent to final adjudication by the bankruptcy court. See id. at 2608, 2614, 2617; accord Lyondell Chem. Co., 467 B.R. at 720 (applying these three considerations in deciding motion to withdraw bankruptcy reference).
a. Public Versus Private Rights
The first consideration under Stem is whether the case involves “public rights” such that it may be assigned to a non-Article III court for final resolution. See 131 S.Ct. at 2611-15. In Stem, the Supreme Court recognized that the public rights “exception has been the subject of some debate,” but concluded that it was limited to “cases in which the claim at issue derives from a federal regulatory [531]*531scheme, or in which resolution of the claim by an expert government agency is deemed essential to a limited regulatory objective within the agency’s authority.” Id. at 2611, 2613; see also Granfinanciera, S.A. v. Nordberg, 492 U.S. 33, 55-56, 109 S.Ct. 2782, 106 L.Ed.2d 26 (1989) (holding that public rights doctrine did not encompass trustee’s claim for fraudulent conveyance); Thomas v. Union Carbide Agric. Prods. Co., 473 U.S. 568, 588-92, 105 S.Ct. 3325, 87 L.Ed.2d 409 (1985) (concluding that rights provided by statutory compensation and arbitration scheme were public rights); N. Pipeline Constr. Co. v. Marathon Pipe Line Co., 458 U.S. 50, 69-70, 102 S.Ct. 2858, 73 L.Ed.2d 598 (1982) (plurality opinion) (describing the public rights doctrine).
Regardless of the exact contours of the public rights exception, the state law breach of contract claim here is clearly outside its bounds. In Northern Pipeline, the Supreme Court held that the post-petition breach of contract and misrepresentation claims at issue did not involve public rights, and, therefore, the bankruptcy court did not have the constitutional authority to finally adjudicate them. See 458 U.S. at 71, 102 S.Ct. 2858 (plurality opinion) (rejecting argument that postpetition breach of contract claim involved public rights and explaining that “the restructuring of debtor-creditor relations, which is at the core of the federal bankruptcy power, must be distinguished from the adjudication of state-created private rights, such as the right to recover contract damages .... The former may well be a ‘public right,’ but the latter obviously is not.”); id. at 91, 102 S.Ct. 2858 (Renhquist, J., concurring) (concluding that breach of contract claim could not be adjudicated in bankruptcy court under the public rights doctrine); see also Stern, 131 S.Ct. at 2611, 2615 (holding that a “state law action independent of the federal bankruptcy law and not necessarily resolvable by a ruling on the creditor’s proof of claim in bankruptcy” is outside the public rights doctrine, and in fact, requires “the most prototypical exercise of judicial power: the entry of a final, binding judgment by a court with broad substantive jurisdiction, on a common law cause of action, when the action neither derives from nor depends upon any agency regulatory regime” (emphasis in original)); Granfinanciera, 492 U.S. at 55-56, 109 S.Ct. 2782 (describing Northern Pipeline’s holding that “state-law causes of action for breach of contract or warranty are paradigmatic private rights, even when asserted by an insolvent corporation in the midst of Chapter 11 reorganization proceedings”). Therefore, the public rights doctrine does not permit final determination of Plaintiff’s claim by the bankruptcy court.
Plaintiff argues that under U.S. Lines, Inc. v. American Steamship Owners Mutual Protection & Indemnity Ass’n, 197 F.3d 631 (2d Cir.1999), the post-petition breach of a prepetition contract in this case is a “core” proceeding that should remain in bankruptcy court. (Plaintiffs Mem. in Opp. to Def.’s Mot. for Withdrawal of the Ref. (“Plaintiffs Mem.”) 9-11.) In U.S. Lines, the Second Circuit issued three opinions to explain that the breach of contract claim for indemnity insurance contracts in that case was “core” and should not have been withdrawn from the bankruptcy court. Writing for the court, Judge Walker reasoned that a proceeding can be core if either “(1) the type of proceeding is unique to or uniquely affected by the bankruptcy proceedings, or (2) the proceedings directly affect a core bankruptcy function.” U.S. Lines, 197 F.3d at 637 (citations omitted). He explained that the insurance contracts at issue would have “a significant impact on the administration of the [bankruptcy] estate,” given that they were arguably the most important asset of the estate, and thus the dis[532]*532pute was a “core” proceeding. Id. at 634. In concurring, Judge Calabresi thought it best to “defer the matter [of whether all post-petition breaches of pre-petition contracts are core] to another day,” though he indicated that he would be “inclined to favor a case-by-case approach.” Id. at 643 (Calabresi, J., concurring). And, Judge Newman proposed a “bright-line rule that treats as core proceedings all suits alleging post-petition breaches of pre-petition contracts.” Id. at 641 (Newman, J., concurring).
The case at hand is distinguishable from U.S. Lines. Unlike the insurance contract in that case, there is no allegation that the coal Contract here involves the most important asset of the bankruptcy estate. Although Danskammer’s claim clearly does involve some of the estate’s property, such involvement alone is not sufficient to render a claim core. See id. at 638 (collecting cases); Orion, 4 F.3d at 1102 (finding a post-petition breach of a pre-petition contract to be non-core); Enron Power Mktg., Inc. v. City of Santa Clara, No. 01-CV-7964, 2003 WL 68036, at *9 (S.D.N.Y. Jan. 8, 2003) (explaining that because the post-petition breach “causes of action are essentially contract claims dressed up as bankruptcy claims, they must be considered ‘non-core’ ”). Only Judge Newman’s bright line approach that all post-petition breaches must be “core” favors Danskammer’s position. However, such an approach has never been adopted within or by the Second Circuit. See, e.g., Enron Power Mktg., Inc., 2003 WL 68036, at *9 (finding a post-petition breach of contract claim to be non-core). In any event, even if the present claim were designated “core” by Judge Newman’s post-petition bright line, because it is a private right and does not meet any of the other Stem exceptions (as discussed below), the bankruptcy court may not finally adjudicate the claim, and this Court would be required to review any proposed findings de novo. Thus, adjudication of this claim by the bankruptcy court would not satisfy the Oñon court’s intent to prevent duplicative review.
b. Whether Claim Would Be Resolved in Ruling on Proof of Claim
The Stem Court also considered whether the “process of adjudicating [a] proof of claim would necessarily resolve [a state-law] counterclaim.” 131 S.Ct. at 2617. In this case, the primary facts at issue in the breach of contract claim — Peabody’s alleged failure to deliver the coal shipment and resulting damages — will not be resolved by the bankruptcy court’s adjudication of Danskammer’s title 11 petition,
c. Consent
Finally, Peabody has not consented to adjudication by the bankruptcy court. See id. at 2607-08, 2614 (suggesting that consent could permit final adjudication by the bankruptcy court when the public rights doctrine does not apply); see also Fed. R. Bankr.P. 7012(b) (requiring “express consent” of the parties to allow final adjudication in non-core proceedings); Men’s Sportswear, Inc. v. Sasson Jeans, Inc., 834 F.2d 1134, 1138 (2d Cir.1987) (“[A] court should not lightly infer from a litigant’s conduct consent to have private state-created rights adjudicated by a non-Article III bankruptcy judge.”). It was this district’s standing order that automatically referred this case to the bankruptcy court, and Peabody, by its motion, has declined to consent to final adjudication of this case in bankruptcy court.
Because none of the three exceptions applies here, Article III prohibits the bankruptcy court from issuing a final determination of Danskammer’s contract claims. This conclusion tips the scales toward withdrawal.
2. Additional Oñon Factors
Oñon dictates consideration of additional factors before determining whether [533]*533withdrawal of the reference is appropriate. See Lyondell Chem. Co., 467 B.R. at 723 (“The bankruptcy court’s authority to enter final judgment on claims is not determinative in deciding whether to withdraw the reference.... ”). In this case, however, the additional Orion factors also support withdrawal of the reference.
Under Orion, district courts should consider the most efficient use of judicial resources. The determination as to whether the bankruptcy court could issue a final determination is “pivotal,” Orion, 4 F.3d at 1102, because if a district court must review recommendations de novo, “it would be inefficient to allow the[ ] proceedings to go forward, knowing that they will have to be substantially repeated,” Dev. Specialists, Inc., 462 B.R. at 472. On the other hand, in cases where the bankruptcy court is more familiar with the record or already has extensive experience in the matter, it may be most efficient for the bankruptcy court to propose recommendations first, even though the district court ultimately would have to review them de novo. See Lyondell Chem. Co., 467 B.R. at 723 (denying motion to withdraw reference where bankruptcy court had already overseen discovery and begun work on several motions to dismiss); Adelphia Recovery Trust, 2012 WL 264180, at *7 (explaining that the bankruptcy court has “a wealth of knowledge ... having overseen ... this action for seven years”); Extended Stay, Inc., 466 B.R. at 206 (“Judicial economy would be promoted by allowing the bankruptcy court, already familiar with the extensive record in this case, to initially adjudicate these cases.”).
Here, Defendant’s Motion was filed shortly after the Complaint was filed, and no discovery or extensive motion practice has come before the bankruptcy court. As a result, the bankruptcy court likely does not have extensive familiarity with the record related to the Complaint. Danskammer claims that it would be more efficient to conduct all proceedings in one court (Plaintiffs Mem. 12), but this does not account for the fact that this Court would ultimately be required to review de novo the bankruptcy court’s proposed findings as to the contract claim. Thus, withdrawal of the reference is necessary in order to adjudicate the proceedings in a single court, and efficiency considerations weigh in favor of granting the Motion for Withdrawal.
Orion also advises district courts to consider the prevention of forum shopping. There is no indication that forum shopping was Peabody’s motivation, as opposed to a genuine desire for more efficient adjudication. See Lyondell Chem. Co., 467 B.R. at 725 (“It is unclear whether the defendants are engaged in forum shopping or simply believe that withdrawal of the reference will reduce the time and expense of litigation.”). Therefore, this consideration does not cut one way or the other.
The final Orion factor is whether the bankruptcy court’s adjudication of the claim would promote uniformity of bankruptcy administration. To evaluate whether a benefit to uniform administration exists, courts look to the nature of the cause of action. Courts routinely have found no benefit where claims are based on state law. See, e.g., Dev. Specialists, Inc., 462 B.R. at 473 (finding that claims based on New York state partnership and contract law would have “no impact that would require uniform, coordinated adjudication before the Bankruptcy court”). In contrast, courts have found a benefit where the claims are based on bankruptcy law itself. See Arbco Capital Mgmt., LLP, 479 B.R. at 268 (finding a benefit to uniform bankruptcy administration where claims focused on specific provisions of the Bankruptcy Code); Extended Stay, Inc., 466 B.R. at 207 (discussing benefit of bank[534]*534ruptcy court administration where claims likely involved “novel issues of bankruptcy law”). Danskammer’s claims in this case are based in state contract law, and there is no indication that any bankruptcy-specific legal analysis will be required. Danskammer argues that the pending motion to compel arbitration in the bankruptcy court is reason to maintain the reference. (Plaintiff's Mem. 13.) Although bankruptcy courts may have experience resolving motions to compel arbitration, see, e.g., In re Millenium Sea Carriers, Inc., 275 B.R. 690 (S.D.N.Y.2002), such experience is not bankruptcy specific.2 Thus, withdrawing the reference likely would not harm the uniformity of bankruptcy administration.
In sum, an analysis of the Orion factors, as modified by Stem, supports granting the Motion for Withdrawal. Under Stem, the bankruptcy court lacks constitutional authority to make a final determination in this case. As described above, the other Orion factors also support withdrawal of the reference considering the overall judicial efficiency, the lack of evidence of forum shopping, and the lack of impact on the uniformity of bankruptcy administration.3
III. Conclusion
For the reasons stated herein, Defendant’s Motion to Withdraw the Reference is granted. The Clerk of Court is respectfully directed to terminate the pending motion. (Dkt. No. 1.)
