From 1933 to 2009, the U.S. House of Representatives considered 107 contested election cases. The vast majority of these cases were resolved in favour of the contestee, a term referring to a Member or Member-elect of the House of Representatives whose election was challenged. It appears that of the 107 contested election cases considered by the House since 1933, in at least three cases, the House ultimately seated the contestant, and in at least one case, the House ultimately refused to seat any individual, declaring a vacancy. In the majority of the other cases, the contest was dismissed based on a variety of reasons. This book explores the summaries of contested election cases with a focus primarily on the nature of the contest and the disposition of the case.
