Twentieth Amendment Law and Legal Definition
The Twentieth Amendment is the constitutional amendment that established the date for presidential inauguration as January twenty and the date for congressional convention as January three. It was ratified in 1933. It was popularly known as Norris Lame Duck Amendment, since it eliminated the December to March Congressional lame duck short sessions that resulted from constitutionally and legislatively established dates for the beginning (December) and close (March in odd numbered years) of congressional sessions.
