In goyishe courts. That is antithetical to Torah Judaism and its laws for its courts and evidence”
However, Dina d’malchusah, dina, and molestation is a very serious crime in the secular courts. Therefore, we cannot hide an accusation, just because the Torah standard of proof is higher. we still have to abide by the law of the land. (I am not suggesting turning someone over to the courts without proof that is incontrovertible).
