Competent To Stand Trial
N.J.S.A. 2C:4-4 — the elements of being competent to stand trial, written out
Competency is a question about the present: whether the person can understand the proceedings and help with the defense now. The defendant's mental state at the time of the offense is a different question, which this page does not cover.
The rule. No person who lacks capacity to understand the proceedings or to assist in their own defense is tried, convicted or sentenced so long as the incapacity endures.
- The capacity to appreciate their presence in relation to time, place and things.
- Understanding that they are in a court charged with an offense, that there is a judge, a prosecutor who will try to convict, and a lawyer who will defend.
- Understanding that they would be expected to tell the facts if they choose to testify, and the right not to.
- Understanding that a jury may decide guilt, or the consequences of a guilty plea and the rights it waives.
- The ability to participate in an adequate presentation of their defense.
Those are what the proofs establish for a person to be considered competent to stand trial.
Restoration treatment, commitment after a finding of incompetence, how long a case can stay suspended, and the insanity defense are set out in other sections and are not on this page. Whether a particular person is competent is decided by a court on evidence, and is a question for a licensed New Jersey attorney.
