A bill to amend title 28, United States Code, to limit the appellate jurisdiction of the Supreme Court in certain cases relating to the apportionment of population among districts from which Members of Congress are elected.

Provides that the Supreme Court shall not have appellate jurisdiction to review any case in which the trial court has determined the legality of the apportionment of population among the districts of a State from which Members of the House of Representatives are elected unless: (1) the trial court found that the population of any district in the State is less than 90 percent of the population of the district having the highest population in the State; or (2) the only questions presented were clearly erroneous, whether any district's boundaries were drawn so as to discriminate against any racial or ethnic group, or whether procedural or evidentiary errors were committed by the trial court. (Adds 28 U.S.C. 1259)
