Newly Discovered Evidence in Indiana Post-Conviction Cases

A witness comes forward years later. A box of police files turns up. A lab test nobody ran finally gets run. Evidence that didn't exist at trial — or existed but couldn't be found — is one of the most powerful things that can surface in a closed case. In Indiana, though, it doesn't reopen anything on its own. There's a structured test, and it asks a lot.

Here's how newly discovered evidence works in Indiana post-conviction proceedings: the nine factors courts run it through, where DNA testing fits, what a Brady claim is, and why the first petition has to be complete.

Why This Goes in a PCR Petition, Not an Appeal

Newly discovered evidence almost always belongs in a post-conviction petition under PCR Rule 1, not a direct appeal. An appeal is confined to the trial record — the transcripts, exhibits, and filings that were already part of the case. New evidence is, by definition, outside that record, so an appellate court can't receive it or weigh it.

Post-conviction is the exception. It's a separate civil action where the court can take new evidence, hear testimony, and look at the full picture. That's where these claims live. For the step-by-step on how a PCR case moves from petition to hearing, see our PCR Rule 1 procedural guide.

The Nine Factors (Carter v. State)

Indiana courts run newly discovered evidence through a nine-factor test set out in Carter v. State, 738 N.E.2d 665 (Ind. 2000), which restates the long-standing test from Fox v. State, 568 N.E.2d 1006 (Ind. 1991). To get a new trial, the petitioner has to show the evidence:

1. Was discovered after the trial
2. Is material and relevant
3. Is not merely cumulative
4. Is not merely impeaching
5. Is not privileged or incompetent
6. Could not have been found before trial through due diligence
7. Is worthy of credit
8. Can be produced at a retrial
9. Will probably produce a different result

You need all nine. Courts usually call the last one — that the evidence "will probably produce a different result" — the heart of the test. That doesn't mean proving you'd win a retrial. It means the new evidence, weighed against the whole trial record, raises a real probability of a different outcome.

Two factors sink a lot of petitions. Evidence that only attacks the credibility of a witness who already testified is impeaching, and impeachment evidence usually doesn't clear the bar unless it's strong enough to likely change the result. Evidence that just piles onto what the jury already heard fails as cumulative.

Witness Recantations

When a trial witness later says their testimony was false, Indiana courts treat it carefully, and for good reason. Witnesses get pressured. Memories shift. There's always the worry that a willing recanter was found rather than the truth. So a recantation isn't automatically credible or automatically enough. It has to clear the same nine factors as anything else, and it often struggles with the "merely impeaching" one.

That said, a credible, corroborated recantation — especially alongside other evidence of innocence — can carry a petition. It comes down to the facts, the record, and how believable the witness is.

Post-Conviction DNA Testing (IC § 35-38-7)

Indiana has a separate statutory path for DNA testing of biological evidence in closed cases: Indiana Code § 35-38-7. It's distinct from a PCR Rule 1 petition. A petitioner files with the sentencing court and has to make a prima facie showing that:

• The evidence is material to identifying who committed the offense
• A sample is in the State's possession or control, with a sufficient chain of custody
• The evidence either wasn't tested before, or newer testing would give more discriminating or contradictory results

If the court orders testing and the results come back favorable, those results can then support a post-conviction petition under Rule 1. The two work together: the DNA statute is how you get the testing, and PCR is how you get relief if the testing backs the claim.

Brady Violations (Evidence the State Hid)

Brady v. Maryland, 373 U.S. 83 (1963) holds that due process requires the prosecution to turn over material favorable evidence — both directly exculpatory evidence and material that impeaches a State witness. A Brady violation has three parts:

• The prosecution suppressed evidence (didn't disclose it)
• The evidence was favorable to the defense (exculpatory or impeaching)
• The evidence was material — there's a reasonable probability the result would have been different had it come out

Brady claims go in PCR petitions here. Since they involve evidence the State had but never disclosed — evidence outside the record — they generally can't be raised on direct appeal without first building the facts in a post-conviction proceeding. And materiality doesn't require proving the disclosure would have produced an acquittal, only a reasonable probability of a different outcome.

The Rule Against Successive Petitions

One of the most consequential pieces of PCR practice is the tight limit on successive petitions. Under PCR Rule 1, § 12, someone who's already litigated one petition can't just file another. They first need authorization from the appellate court, and they have to show a reasonable possibility that relief is available.

That has a direct bearing on newly discovered evidence: a claim that was available when the first petition was filed — including evidence that could have been found and raised then — is generally barred from a successive petition. If the evidence existed and was discoverable the first time around but didn't make it in, raising it later gets much harder. Which is exactly why the scope of that first petition matters so much.

What Relief Looks Like

If a newly discovered evidence claim succeeds, the usual remedy is a new trial. The court sets the conviction aside and orders a retrial, and the prosecution decides whether to go again. That's not an acquittal. It's a fresh start — new evidence, new jury, and whatever the State can still put on. Less often, a court may find the new evidence so overwhelming that no reasonable jury could convict and vacate outright, without a retrial. That's rare.

Working with an Attorney

Newly discovered evidence claims are some of the most fact-intensive in post-conviction law. Sizing up whether evidence meets the Carter factors, tracking it down and authenticating it, handling the due-diligence question, and fitting it into the broader petition without foreclosing future claims — that's careful work. An attorney who handles PCR in Indiana can tell you whether what you have clears the threshold and how it fits the bigger picture.
