Just received this question :
Take this situation: A man regularly abuses a young girl He is not her brother, not her father, etc., so it is not Gilui arayot.The simple answer - 1) if you know for certain that these are the facts and he is still abusing her or others - is to call the police since this is viewed as a case of pikuach nefesh. The fact that this does not involve a specific sexual prohibition which is punishable by court or by kares - it still is prohibited because of many other Torah prohibition. 2) If it is only a suspicion - then contact someone who is experienced in these matters - whether a rabbi, psychologist or social worker - and ask how to proceed. Do not consult people who are not experienced in issues of abuse.
In this case, does she at all have a case against him according to torah law? Or can she just ask for a money settlement because she lost her virginity (if this is the case)? If he goes on abusing her for several years, will this make a difference (as compared to if he does it just one time)?
Has she a case to bring him to civil authorities? I would be very grateful for an answer to this question
However if this is in regard to past activity and he no longer abuses and there is absolutely no possibility he will abuse in the future - the situation is different. In that case you need to consult with rabbinical authorities as well as a lawyer and experienced mental health expert.
Rav Eliashiv: Question: If someone is sexually abusing a boy or a girl in circumstances which we can’t stop him from continuing his evil deeds – is it permissible to notify the government authorities? Answer:...However, it is permitted to notify the government authorities only in the case which it is certain that the accused has been sexually abusing children. Informing the authorities in such a case is clearly something for the well being of the society (tikun olam). However in a case where there is no proof that this activity is happening but it is merely a conjecture or suspicion, if we permit the calling of the authorities - not only would it not be an improvement (tikun olam) - but it would destroy society. That is because it is possible that allegations are being made solely because of some bitterness the student has against his teacher or because of some unfounded fantasy. As a result of these false allegations the accused will be placed in a situation for which death is better than life – even though he is innocent. Therefore I do not see any justification for calling the authorities in such circumstances.1) pikuach nefesh - Rav Eliyashiv [heard from Rav Maier Horowtiz - the Bostoner Rebbe's son] and Rav Sternbuch [heard directly] have clearly stated sexual abuse destroys the person and is thus pikuach nefesh. Simply put the person who is doing this is no different than someone trying to murder her. You must use the minimum effective action that will protect her. If it is clear that this is happening - call the police. The perpetrator is a rodef.
2) physically harming another person is prohibited
3) psychological harm is prohibited by "lo sono" Vayikra 25:17
4) embarrassing and degrading another person is prohibited
5) there is also a Torah requirement to stop a person from sinning.
6) this is also Torah violation of "loving your fellow as yourself"
7) there is a need to rebuke a sinner
8) the disgusting behavior of this individual degrades the spritual status of all Jews - through the mechanism of arvus.
9) there is a Torah prohibition of standing idly by while someone is being harmed
