In Durousseau v. United States (1810) 10 U.S. 307, the Supreme Court found that the "appellate powers of this court" are not created by statute but are "given by the constitution". As stated by Chief Justice Marshall, where the whole context of the law demonstrates a particular intent of the legislature to effect a certain object, some degree of implication may be called in to aid that intent. (Durousseau v. United States, 10 U.S. 307, 314.)
