Nathan Clifford, Railway Company v. Philadelphia…
“ None of the other companies have any such immunity from increased taxation, and if construed to have that effect in favor of the defendant company it would have an extremely invidious operation at the expense of all other similar companies. Invidious exemptions are not favored, nor ought they to be, as they are in principle utterly opposed to the rule of equality, which ought always to prevail in imposing public burdens. ”
