Criminal Competency Evaluation Legal Procedure Explorer
When a judge orders a pre-trial competency evaluation in a felony criminal proceeding, trial proceedings are suspended. Step through the constitutional workflow mandated under Dusky v. United States (362 U.S. 402) and Jackson v. Indiana (406 U.S. 715) to simulate judicial rulings, forensic tracks, and restoration safeguards.
When bona fide doubt exists regarding defendant's present capacity, criminal proceedings are stayed immediately under constitutional mandate. The court appoints certified forensic psychiatrists or psychologists.

Legal Comparison: Competency to Stand Trial (CST) vs. Insanity Defense (NGRI)
Public reporting frequently conflates pre-trial competency with criminal responsibility. Here is the statutory distinction:
Competency to Stand Trial (CST)
- Temporal Focus: Defendant's present mental state right now during pre-trial and trial proceedings.
- Constitutional Standard: Dusky v. United States (rational and factual understanding + capacity to assist defense counsel).
- Who Can Raise: Defense, Prosecution, or Judge sua sponte (at any stage before sentencing).
- Outcome if Incompetent: Trial postponed; defendant committed to state forensic facility for psychiatric restoration. Guilt/innocence is never adjudicated while incompetent.
Not Guilty by Reason of Insanity (NGRI)
- Temporal Focus: Defendant's mental state at the exact time of the alleged offense in the past.
- Legal Standards: M'Naghten Rule (inability to know nature or wrongfulness of act) or Model Penal Code / ALI standard.
- Who Can Raise: Defense only (as an affirmative defense during trial plea).
- Outcome if Acquitted: Verdict of NGRI; defendant committed to psychiatric institution until proven no longer dangerous to self or society.
