42 U.S. (1 How.) 311
A state law, passed subsequently to the execution of a mortgage, which declares that the equitable estate of the mortgagor shall not be extinguished for twelve months after a sale under a decree in chancery, and which prevents any sale unless two-thirds of the amount at which the property has been valued by appraisers shall be bid therefor, is within the clause of the tenth section of the first article of the Constitution of the United States, which prohibits a state from passing a law impairing the obligation of contracts.
