<P> The expression "lame duck" originally applied in 18th century Britain to bankrupt businessmen, who were considered as "lame" in the sense that the impairment of their powers rendered them vulnerable, like a game bird injured by shot . By the 1830s, the usage had been extended to officeholders whose service already had a known termination date . In current American usage, for instance, a President is considered a "lame duck" not only if he has been defeated for re-election, or after his successor has been elected, but also whenever he cannot be, or is known not to be, a candidate for reelection . </P> <P> Members of Congress in similar circumstances are also considered lame ducks . The expression may accordingly be applied to Members who are known not to be seeking re-election as well as to those who have been defeated . In particular, however, after an election of Congress, all the Members who did not gain reelection can be described as lame ducks until the term of the new Congress starts . When the previously sitting Congress, which includes these Members, meets in a post-election session, this session is called a lame duck session as well . </P> <P> The possibility of a lame - duck session of Congress in the modern sense began in 1935, when the 20th Amendment to the Constitution took effect . Under this amendment, ratified in 1933, Congress meets in a regular session on January 3 of each year, unless in the previous session it passes a law changing the date . Also, the terms of Members begin and end on January 3 of odd - numbered years . Under these arrangements, any meeting of Congress after election day (in November of even - numbered years), but before the following January 3, is a lame duck session . </P> <P> Since 1935 there have been 16 lame - duck sessions . The most recent one occurred at the end of the 113th Congress in 2014 . This report examines only the specific lame duck sessions that have occurred since 1935, not those that occurred routinely before this date, as explained in the following section . </P>
