1. By mandamus, suit, action, or proceeding at law or in equity to compel the authority or its officers, agents or employees to perform each and every term, provision and covenant contained in any contract of the authority with or for the benefit of such obligee, and to require the carrying out of any or all such covenants and agreements of the authority and the fulfillment of all duties imposed upon the authority by the Housing Authorities Law of 1947.
2. By suit, action or proceeding in equity, to enjoin any acts or things which may be unlawful, or the violation of any of the rights of such obligee of the authority.
