As noted above, a local government may only enter into a contract that is within the scope of its charter. A contract to do something beyond its power is void and unenforceable, and in fact the local government will be prohibited from performing its obligations under such a contract. The private party who performs under such a contract will have no means of recovery, even under equitable theories such as equitable estoppel, implied contract, quantum meruit, and unjust enrichment. This limitation also applies where the subject of the contract is permissible under the charter, but the manner in which the contract is made or awarded violates proscriptions set forth in the charter. For example, if the charter requires that contracts for provision of a public service be awarded to the lowest bidder in an open bidding process, and such a process is not used to award the contract, then the contract itself is void and the private party to the contract will have no recourse to enforce the local government's obligations thereunder.
