You discover evidence after your conviction that could have changed the outcome at trial. Maryland courts treat convictions as final. Reopening a case requires more than finding something new. You must meet a specific legal standard that most evidence does not satisfy.
Courts balance the need for finality against the possibility that a conviction was wrong. The law provides a path to challenge the outcome, but that path has limits. Although Maryland allows eligible individuals to file actual innocence petitions at any time, the evidence must still meet specific requirements concerning when it could have been discovered.
What makes evidence newly discovered under Maryland law
Evidence generally qualifies as newly discovered when it could not have been discovered through reasonable diligence in time to seek a new trial. It must also meet the applicable standard for relief, which depends on whether the conviction resulted from a trial or a guilty plea. Courts consider the facts known to you when deciding whether earlier discovery was possible.
The standard also depends on how your case ended. If you went to trial, the new evidence must create a substantial or significant possibility that the outcome would have been different. If you pleaded guilty, including Alford pleas and nolo contendere pleas, you must prove actual innocence by clear and convincing evidence. Maryland’s actual innocence law explains both standards.
What types of evidence may support relief
Several types of evidence may qualify under Maryland law:
- A witness who comes forward with information they previously withheld
- Forensic testing not available at the time of trial, such as DNA analysis
- Documents or records that were inaccessible during trial
- Expert testimony based on scientific methods that did not exist earlier
- Physical evidence that surfaces after conviction
- Recanted testimony from a prosecution witness
Courts examine recanted testimony carefully. The judge considers whether the recantation is credible and whether it could change the outcome.
When evidence fails the legal test
Evidence that could have been discovered through reasonable diligence in time to seek a new trial generally will not qualify. Evidence that repeats what the jury already heard or offers only minor impeachment value may also fall short. The evidence must bring something new that could affect the outcome.
Protecting your right to present new evidence
Document and preserve newly discovered evidence right away. This protects your ability to seek relief. Maryland offers different paths depending on the evidence and the time since your conviction. A post-conviction attorney can evaluate whether your evidence meets the legal standard and find the best filing strategy.
