A treaty is an express agreement under international law entered into by actors in international law, namely sovereign states and international organizations.
bill & act
A bill is a proposed law under consideration by a legislature.] A bill does not become law until it is passed by the legislature and, in most cases, approved by the executive. Once a bill has been enacted into law, it is called an act or a statute.
都是立法機關制定的法案，雖然未定案前被稱做bill，可是有許多有名的法案仍然以從前它的原名成為立案後的名稱，如Bill of Rights(美國憲法10條修訂案，為保障人身自由權力)，GI Bill(二次世界大戰退伍軍人福利案)...等等‧
