David Josiah Brewer,
League v. Texas — Opinion of the Court
“ But it contains no prohibition of retrospective legislation as such, and therefore now, as before, the mere fact that a statute is retroactive in its operation does not make it repugnant to the Federal Constitution.As the state may, in the first instance, enact that taxes shall bear interest from the time they become due, so, without conflicting with any provision of the Federal Constitution, it may in like manner provide that taxes which have already become delinquent shall bear interest from the time the delinquency commenced. ”
