thinks he should have in the correctness of factual conclusions for a particular type of adjudication.”
In re Winship, 397 U. S. 358, 370 (1970) (Harlan, J., concurring). Three standards of proof are generally recognized, ranging from the “preponderance of the evidence” standard employed in most civil cases, to the “clear and convincing”
6 standard reserved to protect particularly important interests in a limited number of civil cases, to the requirement that guilt be proved “beyond a reasonable doubt” in a criminal prosecution. See
Addington v.

Woodby v.
INS, 385 U. S. 276, 285 (1966) (deportation);
Chaunt v.
United States, 364 U. S. 350, 353 (1960) (denaturalization);
Schneiderman v.
United States, 320 U. S. 118, 159 (1943) (denaturalization). However, the Court has never required the “beyond a reasonable doubt” standard to be applied in a civil case. “This unique standard of proof, not prescribed or defined in the Constitution, is regarded as a critical part of the ‘moral force of the criminal law,’
In re Winship, 397 U. S., at 364, and we should hesitate to apply it too broadly or casually in noncriminal cases.”
Addington v.
Texas, supra, at 428.
Thus while a State may require proof beyond reasonable doubt in an obscenity case, that choice is solely a matter of state law. The First and Fourteenth Amendments do not
