In the Americas, parliamentary term limits exist in Bolivia (two consecutive terms), Costa Rica (no consecutive term), Ecuador (two consecutive terms) and Venezuela (two consecutive terms). In 2014, the Mexican Congress passed a constitutional amendment lifting the one-term limits and thus allowing for the re-election of federal representatives and senators, as well as city mayors and local representatives. In Peru, Congress approved, last September, a constitutional amendment to re-establish bicameralism. At the same time, it approved an additional constitutional amendment to ban the immediate re-election of legislators. According to this amendment, neither representatives nor senators will be able to run for immediate re-election in their respective chambers. These two amendments were submitted to a national referendum on 9 December 2018; the first was rejected, while the second was approved. With regard to re-election of majors and regional governors, Congress approved in 2015 a constitutional amendment prohibiting their immediate re-election. In 2018, the Peruvian Constitutional Court confirmed the constitutionality of this amendment. The United States Constitution does not allow for term limits for members of the US Congress.
