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This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel.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.

3 Appellate Case: 25-1312 Document: 13-1 Date Filed: 11/19/2025 Page: 4

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
