    Woodie Mack Ashfield, Coleman, FL, pro se.
    John W. Suthers, Attorney General, State of Colorado, Department of Law, Denver, CO, for Defendants-Appellees.
    Before SEYMOUR, HARTZ, and McCONNELL, Circuit Judges.
   ORDER AND JUDGMENT

STEPHANIE K. SEYMOUR, Circuit Judge.

Mr. Woodie Mack Ashfield is a pro se prisoner appealing the district court’s dismissal of this action seeking monetary damages pursuant to 42 U.S.C § 1983. We liberally construe Mr. Ashfield’s pleadings, Haines v. Kerner, 404 U.S. 519, 520, 92 S.Ct. 594, 30 L.Ed.2d 652 (1972), and affirm.

Mr. Ashfield commenced this action against various police officers, district attorneys, and state agencies, alleging they violated his civil rights during their participation in his arrest, conviction, and sentencing. Specifically, he claims his Fifth Amendment right to be free from self incrimination, his Sixth Amendment right to counsel, and his Fourteenth Amendment right to due process were violated by outrageous and unlawful police and prosecutorial conduct. He asks for ten million dollars in damages for these alleged constitutional violations. The district court instructed Mr. Ashfield to show his conviction had been declared invalid, but he failed to address the invalidation issue. Consequently, the district court dismissed his amended complaint as barred by Heck v. Humphrey, 512 U.S. 477, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994), and denied his petition for reconsideration.

In Heck, the Supreme Court held

to recover damages for allegedly unconstitutional conviction or imprisonment, or for other harm caused by actions whose unlawfulness would render a conviction or sentence invalid, a § 1983 plaintiff must prove that the conviction or sentence has been reversed on direct appeal, expunged by executive order, declared invalid by a state tribunal ... or called into question by a federal court’s issuance of a writ of habeas corpus ...

Id. at 486-87, 114 S.Ct. 2364. Although Mr. Ashfield contends he is not seeking invalidation of his sentence but only cornpensatory damages, the question is whether “a judgment in favor of the plaintiff would necessarily imply the invalidation of his conviction or sentence.” Id. at 487, 114 S.Ct. 2864 (emphasis added). If Mr. Ash-field succeeds on his constitutional claims, it would “necessarily imply” his arrest, conviction, and sentence are invalid. If an inmate is challenging the “fact or duration of confinement,” habeas corpus is the only available avenue. Boutwell v. Keating, 399 F.3d 1203, 1209 (10th Cir.2005) (citing Preiser v. Rodriguez, 411 U.S. 475, 93 S.Ct. 1827, 36 L.Ed.2d 439 (1973)). Mr. Ashfield does not allege his conviction has been declared invalid and, consequently, an action under § 1983 is not cognizable.

We therefore AFFIRM the district court’s decision and GRANT Mr. Ash-field’s request to proceed without prepayment of the appellate filing fees. We remind Mr. Ashfield that he is obligated to continue making payments until the entire fee has been paid. 
      
       After examining appellant’s brief and the appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal. See Fed. R.App. P. 34(a)(2) and 10th Cir. R. 34.1(G). The case is therefore submitted without oral argument. This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, or collateral estoppel. The court generally disfavors the citation of orders and judgments; nevertheless, an order and judgment may he cited under the terms and conditions of 10th Cir. R. 36.3.
