If two or more organizations claiming or purporting to represent the same political party file certificates of nomination under the same party designation, or if the certificates indicate the nominations were made by any individual or organization representing the same political party, the secretary of state, within the time prescribed by law for certifying state nominations to the county auditor, shall determine from the best available sources of information which organization filing the certificates is the legally authorized representative of the party. The decision of the secretary of state in determining which organization is the legally authorized representative of the party is subject to review by the district court in a proper action instituted for such purpose.
