Incompetent
Lacking the legal or mental ability to do something. A defendant is incompetent to stand trial when they lack a sufficient present ability to consult with a lawyer with a reasonable degree of rational understanding, or a rational and factual understanding of the proceedings (Dusky v. United States, 362 U.S. 402 (1960)). A court may also find an adult incompetent and appoint a guardian or conservator. Evidence can be called incompetent when the rules do not allow it.
