When executed and acknowledged in conformity with § 7-89-105, the charter shall be filed with the secretary of state. The secretary of state shall examine the charter and, if the secretary of state finds that the recitals contained in the charter are correct, that the requirements of § 7-89-104 have been complied with and that the name is not identical with or so nearly similar to that of another authority already in existence in this state as to lead to confusion and uncertainty, the secretary of state shall approve the charter and accept it for filing. When the charter has been so made, filed and approved, the authority shall constitute a public corporation under the name set out in the charter.
