*The U.S. Supreme Court decided the case of ''Gaffney v. Cummings'', setting the current standard in the U.S. for determining fairness in reapportionment and determination of election districts. In a 6 to 3 decision, written by Justice Byron R. White, the court determined that a mean deviation of less than two percent between the number of persons in the largest and smallest districts was acceptable, and that a ruling on the fairness of a majority political party's geographical construction of a district was a political question reserved to determination by the individual states rather than the federal judiciary. White wrote "minor deviations from mathematical equality among state legislative districts are insufficient to make out a prima facie case of invidious discrimination... if for no other reason than that the basic statistical materials which legislatures and courts usually have to work with are the results of the United States census taken at 10-year intervals and published as soon as possible after the beginning of each decade. These figures may be as accurate as such immense undertakings can be, but they are inherently less than absolutely accurate. Those who know about such things recognize this fact."
