William R. Day,
City of Minneapolis v. Minneapolis Street Railway Company…
“ In construing this section we must bear in mind that the company then had, as we have heretofore said, a contract upon the subject of fares, which limited the city in its right to regulate the same to a reduction not below 5 cents per passenger upon any one continuous line. It needs no argument to demonstrate that the right to charge passenger fares is of the very essence of the contract, essential to the operation and success of the enterprise. ”
