First instance body dealing with electoral disputes

ElectoralJustice: The International IDEA Handbook

 The classification is based on the legalnature of the body competent to make the final ruling on the last challengeprovided for against the election results, even if it is almost neverused.  The competent organ to make the finalruling on national legislative elections in the United States is the House ofRepresentatives or the Senate for the election of their own members, or thewhole of Congress for presidential elections; a concurrent majority vote ofboth the House of Representatives and the Senate is required in order to overturna decision on this matter reached by a state. This has not happened since the1876 presidential election. The most that has happened is that a challenge hasbeen brought before the Supreme Court. In the case of national legislativeelections, there have been very few cases brought before the House ofRepresentatives or the Senate. Nonetheless, in the light of the criterion adopted,  the US  EDRS  falls into  the  category of  those  conferred on  a legislative organ, and notamong those entrusted to a judicial body.
