Peter Vivian Daniel, West River Bridge Company v. Dix…
“ A grant is a contract, and any thing which defeats or impairs rights growing out of it, in a manner inconsistent with the constitution and laws of the State, may be said to impair its obligation. Thus, to take private property for public use without compensation, where the State constitution forbids such taking, is, doubtless, prohibited by that clause of the Constitution of the United States which provides that no law shall be passed impairing the obligation of contracts. ”
