Appeal dismissed by published opinion. Judge King wrote the opinion, in which Judge Thacker and Judge Gibney concurred.
In these proceedings, plaintiff Wayne Oliver filed a complaint in Maryland state court alleging asbestos exposure claims against, among other defendants, Campbell-McCormick, Inc. (“CMC”). In response, CMC filed a third-party complaint against several entities, including General Electric Company (“GE”). GE then removed the litigation to the District of Maryland, prompting Oliver to move to sever his claims and remand them to state court. The federal' district court granted Oliver’s motion and concomitantly retained jurisdiction over CMC’s third-party claims, which the court stayed. See Oliver v. Campbell-McCormick, Inc., No. 1:16-cv-01057 (D. Md. July 18, 2016), ECF No. 106 (the “Order”). CMC appeals from the Order, contending that the district court erroneously severed and remanded Oliver’s claims. As explained below, we dismiss the appeal for lack of appellate jurisdiction—
I.
In December 2015, Wayne Oliver filed his complaint in the Circuit Court for Baltimore City, Maryland, alleging state law claims against CMC, the Walter E. Campbell Company, Inc., and MCIC, Incorporated. CMC then filed its third-party complaint against GE and twelve other third-party defendants, seeking contribution pursuant to the Maryland Uniform Contribution Among Joint Tort-Feasors Act. See Md. Code, Cts. & Jud. Proc. § 3-1401 (the “UCATA”).
By its Order of July 18, 2016, the district court granted Oliver’s motion to sever and remand his claims, but retained jurisdiction over and stayed CMC’s third-party claims. As the court explained in the memorandum opinion accompanying the Order, its discretion to decline to exercise supplemental jurisdiction over a state law claim is circumscribed by § 1367(c), under which “a declination is permitted only when,” inter alia, “the claim ‘substantially predominates over’ the claim [that accords] original or removal jurisdiction.” See Oliver v. Campbell-McCormick, Inc., No. 1:16-cv-01057, at 4,
Additionally, the Opinion recognized that the district court’s discretion is circumscribed by case law, but found that the relevant “‘principles of economy, convenience, fairness, and comity’ ” further “support severance and remand.” See Opinion 4, 6 (quoting Hinson v. Norwest Fin. S.C., Inc.,
CMC timely noted this appeal, summarily asserting that this Court possesses jurisdiction under 28 U.S.C. § 1291. Nevertheless, “before we consider the merits of an appeal, we have an independent obligation to verify the existence of appellate jurisdiction.” See Porter v. Zook,
II.
In its supplemental appellate brief, CMC contends that a remand order based upon a district court’s decimation of supplemental jurisdiction pursuant to 28 U.S.C. § 1367(c) is considered to be a final, appealable decision under 28 U.S.C. § 1291—because it either ends the federal litigation on the merits or qualifies for review under the collateral order doctrine. CMC specifically relies on the collateral order doctrine for our jurisdiction in this appeal from the district court’s Order. For his part, Oliver contests this Court’s § 1291 jurisdiction, but his supplemental brief only cursorily addresses the potential applicability of the collateral order doctrine.
A.
It is true “that a remand order based on § 1367(c) is appealable as a final order pursuant to § 1291.” See Bryan v. BellSouth Commc’ns,
The collateral order doctrine, however, provides another potential avenue for this Court to possess § 1291 jurisdiction. Initially articulated in 1949 by the Supreme Court in Cohen v. Beneficial Industrial Loan Corp., the collateral order doctrine identifies a “small class [of decisions] which finally determine claims of right separable from, and collateral to, rights asserted in the action, too important to be denied review and too independent of the cause itself to require that appellate consideration be deferred until the whole case is adjudicated.” See Cohen,
In assessing whether an appeal qualifies for review under the collateral order doctrine, “[t]he importance of the right asserted has always been a significant part” of the analysis. See Will,
B.
Our analysis of whether the district court’s Order qualifies for review under the collateral order doctrine is further informed by the Supreme Court’s decisions in Moses H. Cone Memorial Hospital v. Mercury Construction Corp.,
Satisfying the first Cohen requirement, the district court orders conclusively determined the disputed abstention issues, in that the Moses H. Cone stay order was “the practical equivalent of an order dismissing the case,” and that the Quacken-bush remand order “disassociate^] [the district court] from the case entirely.” See Quackenbush,
Finally, the rights asserted in the Moses H. Cone and Quackenbush appeals were deemed sufficiently important to meet the importance aspect of the second and third Cohen requirements. In particular, the Quackenbush Court pointed to the “strict duty” of federal courts “to exercise the jurisdiction that is conferred upon them by Congress,” as well as the “exceptional circumstances”
balances the strong federal interest in having certain classes of cases, and certain federal rights, adjudicated in federal court, against the State’s interest in maintaining uniformity in the treatment of an essentially local problem and retaining local control over difficult questions of state law bearing on policy problems of substantial public import.

C.
Even accepting the proposition that the other Cohen requirements of the collateral order doctrine are satisfied, we are unable to conclude that the right asserted by CMC is sufficiently important to qualify for collateral order review. That is, we can assume that the district court’s Order conclusively determined the disputed question of whether Oliver’s claims should be severed and remanded (in satisfaction of the first Cohen requirement); resolved that question completely separate from the merits of the claims (meeting part of the second Cohen requirement); and is effectively unreviewable on appeal from a final judgment as to CMC’s remaining third-party claims (satisfying part of the third Cohen requirement). Cf. Quackenbush,
As we explained in Cobra, the Supreme Court has assessed importance—particularly with respect to the third Cohen requirement—“by first combing its precedent to identify recurring characteristics that merit collateral order appealability, and then comparing those characteristics to the proceeding at hand.” See
Simply put, the right asserted by CMC in this appeal—the right to keep Oliver’s state law claims in federal court pursuant to 28 U.S.C. § 1367—“pales in
That the right asserted by CMC is insufficiently important for our immediate review is amply illustrated by Moses H. Cone and Quaekenbush. In those cases, district courts had abstained from exercising original federal jurisdiction in decisions rendered amidst an abundance of precedent emphasizing the “exceptional circumstances” necessary for a proper abstention. See Quackenbush,
In these circumstances, CMC is unable to show how our failure to review the Order severing and- remanding Oliver’s claims would endanger “a substantial public interest” or “some particular value of high order;” See Will,
III..
Pursuant to the foregoing, we lack jurisdiction in this appeal and are obliged to dismiss it. ■
APPEAL DISMISSED
Notes
. Plaintiff Oliver died in July 2016, after the district court entered the Order. Thus, Oliver's personal representatives, June R. Stearns and Clifford Oliver, are now appel-lees. We refer to them herein as "Oliver.”
. In addition to GE, the third-party defendants are the following: Atwood & Morrill Co., Inc.; Manville Trust Personal Injury Settlement Trust; Aurora Pump; Crane Co.; In-gersoll-Rand Co,, Inc.; Johnson Controls, Inc.; Marotta Controls, Inc.; The Nash Engineering Company; The Weir Group; Velan Valves Corp.; Viking Pump; and Warrant Pumps, Inc.
. The principle that a remand order predicated on § 1367(c) is appealable under § 1291 as a final decision stands in contrast to 28 U.S.C. § 1447(d)'s prohibition against appeal of a remand order premised on § 1447(c). See Bryan,
. Our analysis of the jurisdictional question is not altered by the fact that the Order administratively closed the case in the district court, subject to reopening as warranted to pursue third-party claims. As we have recognized, "an otherwise nonfinal order does not become final because the district court administratively closed 'the case after issuing the order.” See Penn-Am. Ins. Co. v. Mapp,
