Horace Gray, Spencer v. Merchant — Opinion of the Court
“ The constitutional validity of law is to be tested, not by what has been done under it, but by what may by its authority be done. The legislature may prescribe the kind of notice, and the mode in which it shall be given, but it cannot dispense with all notice.' And, on page 190, it was further said: 'The legislature can no more arbitrarily impose an assessment for which property may be taken and sold, than it can render a judgment against a person without a hearing. ”
