John Marshall Harlan,
Gross v. United States Mortgage Company…
“ That the act in question is not repugnant to the constitution, as impairing the obligation of a contract, is, in view of the settled doctrines of this court, entirely clear. Its original invalidity was placed by the court below upon the ground that the statutes and public policy of Illinois forbade a foreign corporation from taking a mortgage upon real property in that state to secure a loan of money. ”
