That's from criminal law, this seems to be a civil act. Also, while we're there, the burden of proof is different -- proof beyond a reasonable doubt vs balance of probabilities.

My point is, at this time we've only just now heard of the accusation. Until the time that I've personally seen all evidence, or it has been determined in a court of law that this man is guilty of the accusations, he has done nothing in my eyes.
I absolutely hate seeing innocent people have their reputations and lives trashed by someone who places a false claim against them. Innocent until proven guilty is a good policy to maintain, especially as everyone contorts a story to fit his or her views and agenda.
I don't disagree that what you point out is the ideal.
Given the 4 word response, I thought I'd mention that standards from criminal law will not apply here and that the case will be decided on a balance of probabilities. I don't know this guy but I do hope he gets a fair shake in court.
