Constitutional jurisdiction had a number of opportunities to deal with (unequal) allocation of seats to constituencies. The most known case-law is that of the Supreme Court of the United States, since the 1962 Baker v. Carr case, where the Court interpreted the Equal Protection Clause of the 14th Amendment to the U.S. Constitution encompasses claims that electoral districts be periodically adjusted or redrawn to account for population shifts among them. More recently, on 28 May 2015, the Constitutional Court of the Republic of Georgia cancelled provisions of the electoral code whose effect was that, in the 2012 parliamentary elections, the number of voters per single-mandate constituency was extremely different (the variation going up to 1 to 22).
