Joseph McKenna, Capital Trust Company v. Calhoun…
“ Liberty in any of its exertions and its protection by the Constitution are of concern. The right to bind by contract and require performance of the contract are examples of that liberty and that protection and they might have resistless force against any interfering or impairing legislation if the contest in the case was simply one between Calhoun and the Arnold estate. But there are other elements to be considered-there is the element of the condition Congress imposed on the subject-matter of the controversy regarded as a condition of its grant. Relief could only be had through legislation. ”
