A person who may have a substantial interest in any decision of the BAR or any officer, or agent of the appropriate governing authority may appeal from any decision of the BAR to the circuit court in and for the county by filing with the clerk of court a petition in writing setting forth plainly, fully, and distinctly why the decision is contrary to law. The appeal must be filed within thirty (30) days after the affected party receives actual notice of the decision of the BAR.
