Changes

In the 20th century, the Supreme Court began allowing states to interfere with prior contracts in the interest of safety, health, morals and the general welfare.  The leading case was ''Home Building & Loan Ass'n v. Blaisdell'' (1934), which allowed a state to impose a moratorium (suspension) on mortgages in combatting deflation during the Great Depression.  The Supreme Court later expanded governmental power to interfere with contracts in ''Exxon Corp. v. Eagerton'' (1983), when a "broad societal interest" was the basis for government to prevent Exxon Corp. from enforcing a contractual right to pass an increased tax onto consumers.

An interesting question is whether the Obligation of Contract Clause has only a retroactive effect in protecting contracts already formed, or also has a prospective application to protect the right to enter into future contracts.  The view of prominent Professor Richard Epstein is that states may change the rules governing future contracts only to provide greater stability and security in contractual obligations.  Examples include a statute of limitations, a statute of frads and recording acts.
