Addington v. Texas
In Addington v. Texas, 441 U.S. 418, 60 L. Ed. 2d 323, 99 S. Ct. 1804 (1978), rev'g, 557 S.W.2d 511 (Tex. 1977), the United States Supreme Court concluded that due process demands clear and convincing proof before the state may involuntarily confine a person in a mental institution.
The Supreme Court instructed:
The function of a standard of proof, as that concept is embodied in the Due Process Clause and in the realm of factfinding, is to "instruct the factfinder concerning the degree of confidence our society thinks he should have in the correctness of factual conclusion for a particular type of adjudication."Id.
