Pennsylvania Coal Co. v. Mahon 260 U.S. 393 (1922) was a case in which the Supreme Court of the United States held that whether a regulatory act constitutes a taking requiring compensation depends on the extent of diminution in the value of the property. The decision thereby started the doctrine of regulatory taking. The Takings Clause originally applied only when the government physically seized or occupied property.
