Joint Resolution
This is a resolution of both Chambers, generally used for limited matters, such as commemorative holidays. Designated as H.J.Res. in the House and S.J.Res. in the Senate, joint resolutions are signed by the President and have the force of law.
Joint resolutions also are used to propose an amendment to the Constitution. In this case, they must be agreed to by a two-thirds majority in each Chamber and by three-fourths of the states. The President does NOT sign this type of joint resolution.
