A telephone company petitioned the railroad commission for a certificate of convenience and necessity and for authority to extend its lines into territory already served by another company. The application was denied by the commission, but upon appeal the circuit court set aside the order. The supreme court held that the orders or determinations of the commission in such matters will not be disturbed by the courts unless unreasonable in the sense that reasonable men might not well differ with respect to their correctness.
