Which obligation continues beyond trial according to the Michael Morton Act?

The obligation that continues beyond the trial according to the Michael Morton Act is the requirement to notify the defense about exculpatory evidence. This is a crucial aspect of the legal process that ensures fairness and justice in criminal proceedings. Under the Act, prosecutors are mandated to disclose any evidence that could prove the innocence of the defendant or mitigate their guilt. This obligation is not limited to the trial phase; it extends beyond, implying that if new exculpatory evidence arises even after the trial has concluded, the prosecution must inform the defense. This mechanism is designed to prevent wrongful convictions and uphold the integrity of the judicial system by ensuring that defendants are aware of all evidence that may affect their case.

Other choices reflect responsibilities and requirements that either pertain specifically to the trial, or that do not have the same continuous obligation post-trial. For instance, the duty to disclose only material evidence and the requirement to submit trial evidence are typically focused on the trial's duration. The responsibility to manage case files also generally relates to the administrative aspects of the trial process rather than ongoing obligations after the trial has ended.
