Joseph,
1. Please cite your sources for these assertions.
2. You are misusing the word “mandate”. The proper word is “compel”, which means beating him until he says”rotzeh ani”. No bet din today has the power to do that under any circumstances. However, a bet din does have the power to instruct him that he should give his wife a get. If he refuses it can issue sanctions against him for contempt of court (e.g. no honors in shul). This is not compulsion as he can decide to forego shul honors (for example) whereas no one can accept continual beating.
