Pierce Butler, City of Paducah v. Paducahry Company…
“ Operating expenses greatly increased between 1914 and the adoption of the franchise ordinance.That the city had power under its charter to prescribe just and reasonable fares from time to time was stated by counsel on the argument and is assumed. The surrender of this power or any part of it is a very grave act; authority to make it must be plain, and the intention so to do must clearly and unmistakably appear. ”
