 However, the term "treaty" has a more restricted sense in American law than in international law.Of the more than 16,000 international agreements entered into by the United States between 1946 and 1999, only 912 were ratified by the required two thirds of the US Senate of the Treaty Clause of the Constitution.The US Supreme Court has also limited the direct effect of ratified treaties, notably in the case of "Medellín v. Texas" (2008).
