SUMMARY ORDER
UPON DUE CONSIDERATION WHEREOF, IT IS HEREBY ORDERED, ADJUDGED, AND DECREED that the judgment of the District Court is AFFIRMED.
Plaintiff-Appellant Andrew Wisoff, pro se, brought a 42 U.S.C. § 1983 action against the City of Schenectady and Hon. Karen A. Drago, Schenectady County Court Judge. In his proposed third amended complaint,1 Wisoff alleged that Judge Drago deprived him of procedural due process by dismissing, without notice and an opportunity to be heard, his appeal of his conviction and fine for city code violations, and that the City improperly benefitted by collecting the fine. Wisoff sought an order vacating the dismissal of his appeal, reinstating a stay on his payment of the fine, and directing the City to reimburse him for the fine. The District Court dismissed the action. The issues on appeal are whether judicial immunity and/or the so-called “Rooker-Feldman ” doctrine barred Wisoffs claims against Judge Drago, and whether Wisoff failed to state a claim against the City pursuant to Monell v. Department of Social Services, 436 U.S. 658, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978). We assume the parties’ familiarity with the underlying facts and the procedural history of the case, to which we refer only as necessary to explain our decision to affirm.
In reviewing the dismissal of Wisoffs complaint, we apply the familiar standards of review. “When reviewing a district court’s dismissal for lack of subject matter jurisdiction pursuant to Fed.R.Civ.P. 12(b)(1), we review factual findings for clear error and legal conclusions de novo.” Close v. New York, 125 F.3d 31, 35-36 (2d Cir.1997). Dismissal of a case for lack of subject matter jurisdiction under Rule 12(b)(1) is proper “when the district court lacks the statutory or constitutional power to adjudicate it.” Makarova v. United States, 201 F.3d 110, 113 (2d Cir.2000).
We similarly “review de novo the grant of a motion to dismiss for failure to state a claim upon which relief can be granted” under Fed.R.Civ.P. 12(b)(6). Harris v. Mills, 572 F.3d 66, 71 (2d Cir.2009). We accept all factual allegations in the complaint as true, and draw all reasonable inferences in the plaintiffs favor. Id. The complaint “must plead ‘enough facts to state a claim to relief that is plausible on its face.’” Ruotolo v. City of New York, 514 F.3d 184, 188 (2d Cir.2008) (quoting Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570, 127 S.Ct. 1955, 167 L.Ed.2d 929 (2007)).
Upon such review, we see no error in the dismissal of Wisoffs claim against Judge Drago for substantially the reasons stated in the District Court’s order— namely, that Wisoff failed to establish subject-matter jurisdiction in light of the Rooker-Feldman doctrine and, in the alternative, that Judge Drago is entitled to judicial immunity. We also conclude that the District Court did not err in dismissing Wisoffs due process claim against the City pursuant to Monell for failure for failure to allege a municipal “policy” or “custom” *30that caused Wisoffs alleged injury. See Board of County Comm’rs v. Brown, 520 U.S. 397, 403, 117 S.Ct. 1382, 137 L.Ed.2d 626 (1997) (citing Monell, 436 U.S. at 694, 98 S.Ct. 2018).2
CONCLUSION
We have considered all of the arguments raised by Wisoff on appeal and find them to be without merit. For the reasons stated above, we AFFIRM the District Court’s May 7, 2013 judgment.
