Do I become exempt from responsibility, and is it permissible for me to own funds acquired through the management committee, despite its violation of the association's or country's laws, if the management committee bears the responsibility?

If you acquire money that is not rightfully yours, whether by mistake or favoritism, it is not permissible for you to keep it, and it must be returned to the granting party. If it is impossible to return it, then donate it to the poor, the needy, and other charitable causes. If you are poor or in need, it is permissible for you to take from it. A judge's ruling does not make lawful what is unlawful.
