Pierce Butler, American Toll Bridge Company v…
“ Section 2845 requires the county board, when granting the franchise, to fix the license tax within specified limits and a rate of toll, which must not raise annually an income exceeding 15 per cent of base. Section 2846 declares that the license tax and the rate of toll so fixed must not be diminished unless receipts are disproportionate to base. Thus plainly the commands are that at first the tolls must be fixed, but not to produce income above the 15 per cent specified, and that the tolls so fixed shall not be diminished unless yield is disproportionate to the defined base. ”
