Says who? Words mean things and legal words mean specific legal things.
What is the legal definition for the purposes of the statute and what is the legal definition of adjudication of mental illness in the state of VA?
It is not a judge signing a temporary detention/evaluation order.
THe keyword is committed. He was involuntarily committed to a psych inst. for evaluaiton. That means the judge was convinced an evaluation was both prudent and necessary for his own welfare, or the welfare of others and the person committed refused it. No judge determines a person mentally ill, they order that docs make the determinaiton, upon the presentation of evidence that indicates to a reasonable person, that the guy is incapable of handling his own affairs(a danger to himself), or a danger to others.
