Lame-Duck Session Law and Legal Definition

Lame duck session is a post-election legislative session in which some of the participants are voting during their last days as elected officials.

In the U.S. a lame duck session of Congress is one that takes place after the election for the next Congress has been held, but before the current Congress has reached the end of its constitutional term. In current practice, any meeting of Congress after election day, but before the following January 3, is a lame duck session. The most important characteristic of a lame duck session is that its participants are the sitting members of the existing Congress, not those who will be entitled to sit in the new Congress.
