A taxpayer who is required by the secretary of revenue to pay a tax that the taxpayer deems improper or unlawful in amount may pay the tax under protest and may recover the tax without interest, if an action is commenced in the circuit court against the secretary within six months after payment and a judgment is granted to the taxpayer. A judgment against the secretary shall be paid out of any money not otherwise appropriated in the state general fund upon a voucher duly approved by the secretary. This remedy is exclusive of all other remedies and no injunction to restrain or delay the collection of a tax claimed to be due may be issued by any court in this state.
