A public corporation is a corporation formed by the state for purposes of local government and administration.1 Public corporations are divided into municipal corporations and the organizations of less extensive powers, such as counties, school districts and the like known as quasi corporations. Municipal corporations are those public corporations which have extensive powers of local government, including the power of making local laws. Quasi corporations have limited powers of government or administration, and lack the power of making local laws.2 The difference in powers between municipal corporations and quasi corporations often leads to important distinctions in the validity of their contracts. The difference in name is unimportant. A county may be included under the term "municipal or other corporation."3
