William O. Douglas,
Clay v. Sun Insurance Office, Ltd…
“ While there are Illinois cases indicating that parties may contract-as here-for a shorter period of limitations than is provided by the Illinois statute, [4] we are referred to no Illinois decision extending that rule into other States whenever claims on Illinois contracts are sought to be enforced there. We see no difficulty whatever under either the Full Faith and Credit Clause or the Due Process Clause. We deal with an ambulatory contract on which suit might be brought in any one of several States. ”
