Any person, including the commission, on behalf of and in the name of the state, aggrieved by any decision of a board of appeals, or any governing body of a political subdivision or any joint airport zoning board who is of the opinion that a decision of a board of appeals is erroneous, after first exhausting the remedies provided by such board, may present to the circuit court in any county in which the board transacts its business, a verified petition setting forth that the decision is erroneous, in whole or in part, and specifying the grounds of the error. Such petition shall be presented to the court within 30 days after the decision is filed in the office of the board. When petitions for review are filed in qualified courts located in different counties, the court in which a petition is filed first shall have exclusive jurisdiction of the matter.
