Defendant - Appellee. _________________________________
ORDER AND JUDGMENT * _________________________________
Before TYMKOVICH, BALDOCK, and FEDERICO, Circuit Judges. _________________________________
Josias Ortiz is a state criminal defendant currently appealing his
conviction in the Colorado Court of Appeals. Andrew Sidley-Mackie was
appointed to represent Ortiz in his state appeal, but Ortiz asked Sidley-
Mackie to withdraw so that he could represent himself pro se. Allegedly,
After examining the briefs and appellate record, this panel has *
determined unanimously that oral argument would not materially assist in the determination of this appeal. See Fed. R. App. P. 34(a)(2); 10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument.
This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Federal Rule of Appellate Procedure 32.1 and Tenth Circuit Rule 32.1. Appellate Case: 25-1312 Document: 13-1 Date Filed: 11/19/2025 Page: 2
Sidley-Mackie refused to do so and instead fraudulently represented to the
Colorado Court of Appeals that Ortiz may not be competent to self-
represent. Based on these allegations, Ortiz filed this federal lawsuit under
42 U.S.C. § 1983 claiming that Sidley-Mackie had violated his
constitutional rights.
The assigned magistrate judge recommended dismissing Ortiz’s
lawsuit for lack of subject matter jurisdiction. Over Ortiz’s objection, the
district court adopted that recommendation and dismissed the lawsuit. We
have jurisdiction under 28 U.S.C. § 1291.
“We review dismissals for lack of subject matter jurisdiction de novo.”
Blue Valley Hosp., Inc. v. Azar, 919 F.3d 1278, 1283 (10th Cir. 2019). Subject
matter jurisdiction may arise due to the existence of a federal question. 28
U.S.C. § 1331. Or it may arise due to diversity of citizenship between the
parties. 28 U.S.C. § 1332. We address each source of jurisdiction in turn.
Federal question jurisdiction exists when a lawsuit “aris[es] under the
Constitution, laws, or treaties of the United States.” 28 U.S.C. § 1331. This
means that we usually have jurisdiction if the plaintiff brings a federal
claim, regardless of whether the claim is a meritorious one. Steel Co. v.
Citizens for a Better Env’t, 523 U.S. 83, 89 (1998). But if the federal claim
is “so insubstantial, implausible, foreclosed by prior decisions of [the
Supreme] Court, or otherwise completely devoid of merit as not to involve a
2 Appellate Case: 25-1312 Document: 13-1 Date Filed: 11/19/2025 Page: 3
federal controversy,” that claim does not confer jurisdiction. Id. (quoting
Oneida Indian Nation of N.Y. v. Cnty. of Oneida, 414 U.S. 661, 666 (1974)).
Here, Supreme Court precedent squarely forecloses Ortiz’s § 1983 claim, so
even though a § 1983 claim is a federal one, federal question jurisdiction is
lacking.
To succeed on his § 1983 claim, Ortiz needed to show that Sidley-
Mackie was acting under color of state law. Schaffer v. Salt Lake City Corp.,
814 F.3d 1151, 1155 (10th Cir. 2016). But in Polk County v. Dodson, the
Supreme Court held that public defenders do not act under color of state
law when representing criminal defendants even though public defenders
are employed by the government. 454 U.S. 312, 318–19 (1981). Since Ortiz
seeks to hold Sidley-Mackie liable for actions taken as appointed defense
counsel – which are private rather than state actions under Polk County –
Ortiz cannot prevail on his claim.
Meanwhile, diversity jurisdiction exists if the parties have diverse
citizenship and the amount in controversy exceeds $75,000. 28 U.S.C.
§ 1332(a)(1). On the face of Ortiz’s complaint, diversity is absent because
both Ortiz and Sidley-Mackie are Colorado citizens. Therefore, diversity
jurisdiction is lacking as well.

For these reasons, we conclude that Ortiz’s appeal lacks any colorable
basis. 1 Accordingly, we deny his pending motion to proceed in forma
pauperis and dismiss his appeal.
APPEAL DISMISSED.

Richard E.N. Federico Circuit Judge
1 Ortiz’s arguments regarding abstention under Younger v. Harris, 401 U.S. 37 (1971), the bar to § 1983 relief under Heck v. Humphrey, 512 U.S. 477 (1994), and Sidley-Mackie’s allegedly illegal actions have no bearing on the issues of subject matter jurisdiction relevant in this appeal. 4
