Actually I think in civil cases it is just by a preponderance of the evidence that he is the culprit that is necessary. Beyond a reasonable doubt is in criminal cases.
Nice! I love to learn. Unfortunately our poster did not include their state, the standard appears to be case/state specific. But, here's something I found on the subject:
U.S. Supreme Court
CALIFORNIA v. MITCHELL BROS.' SANTA ANA THEATER, 454 U.S. 90 (1981)
: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. Texas, 441 U.S. 418, 423 -424 (1979). This Court has, on several occasions, held that the "clear and convincing" standard or one of its variants is the appropriate standard of proof in a particular civil case. See Addington v. Texas, supra, at 431 (civil commitment); Rosenbloom v. Metromedia, Inc., 403 U.S. 29, 52 (1971) (libel); 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."
