Title 18 › PART II — CRIMINAL PROCEDURE › CHAPTER 228A — POST-CONVICTION DNA TESTING › § 3600
A person sentenced to prison or death for a federal crime can file a written request asking the court that convicted them to order DNA testing of specific evidence. The court will order testing only if the person swears they are actually innocent (or that another offense admitted at sentencing would affect their sentence and state remedies were tried), the evidence is tied to the investigation, the evidence is in government custody with an unbroken chain of custody, the evidence was not already tested (or a new, more useful test is now available), the testing is reasonable and scientifically sound, the person gives a defense theory that could prove innocence and is not inconsistent with defenses used at trial, identity of the perpetrator was at issue if there was a trial, the testing could produce new evidence that raises a reasonable chance the person did not commit the crime, the person will give a DNA sample, and the motion is timely (there is a presumption it is timely if filed within 60 months of enactment of the Justice For All Act of 2004 or within 36 months of conviction, whichever comes later). After the motion is filed, the court must notify the Government, allow a response, order an inventory and preservation of the evidence, and may appoint a lawyer for someone who cannot pay. The FBI must do the testing unless the court allows another qualified lab with safeguards. The person pays for testing unless they are indigent, in which case the Government pays. For death sentences, testing must finish within 60 days after the Government responds and the court must act within 120 days after testing is done. Results go at the same time to the court, the person, and the Government. If the DNA excludes the person and the profile meets FBI rules, the court must have it searched in the National DNA Index System (NDIS) and share those results. If results are inconclusive, the court may order more testing or deny relief. If results show the person was the source, the court must deny relief and may find the person made a false claim, require payment of testing costs, notify prison and parole officials, and refer the matter to appropriate officials; a conviction for false assertions carries at least 3 years in prison to run after any other sentence. If the DNA excludes the person, they can ask for a new trial or resentencing, and the court must grant it if the DNA plus all other evidence would likely lead to an acquittal. Other ways to seek DNA testing or post‑conviction relief are not changed, and this motion is not a basis for habeas relief or treated as a section 2255 motion.
