Prosecutor's Denial of Competency Evaluation Not Immediately Appealable Without Showing of Prejudice

In a criminal investigation regarding narcotics offenses, the accused requested a forensic psychiatric evaluation to determine competency at the time of the offense, which the public prosecutor denied. The appellate court declined to hear the accused's complaint against the denial, reasoning that under the relevant procedural rule, a complaint against the rejection of evidence by the prosecutor is inadmissible if the request can be repeated before the trial court without prejudice. Since the accused could repeat the motion later and failed to demonstrate an imminent loss of evidence—especially considering the alleged offenses occurred two to five years prior, rendering immediate assessment of competency already difficult—no prejudice arose from the delay that would justify an immediate appeal.
