This book is an overview of contested election cases in the House of Representatives from 1933 to 2007. The U.S. House of Representatives considered 104 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. The summaries of contested election cases contained in this book focus primarily on the nature of the contest and the disposition of the case. This book only examines cases considered by the House of Representatives involving the question of whether a Member-elect was duly elected, that is, questions regarding elections and returns, not questions regarding qualifications (age, citizenship and inhabitancy).
