President of Argentina
Under the 1994 constitutional amendment, the President serves for four years, with a possibility of immediate reelection for one more term. However, unlike the President of the United States, in Argentina, a person may be reelected again after serving for two terms and staying out of office for the following term. So after serving for two consecutive periods, the president is not allowed to run for a third consecutive one, but may return for the two following elections and so on. There is no limit for a person to be a candidate if he or she does not win the elections.
Term limits in the United States
Many of the proposals center around a term limit for Justices that would be 18 years (Larry Sabato, Professor of Political Science at University of Virginia, suggested between 15 and 18 years). The proposed staggered term limits of 18 years would, according to Calebresi, Lindgren (2006), and Carrington (2005), allow for a new appointment to the Court every two years, which in effect would allow every president at least two appointments. Professor Carrington has argued that such a measure would not require a constitutional amendment as the "Constitution doesn’t even mention life tenure; it merely requires that justices serve during ‘good behaviour’ ". The idea was not without support among Judges, as John Roberts supported term limits before he was appointed to the Supreme Court as Chief Justice. Calebresi, Lingren, and Carrington have also proposed that when justices have served out their proposed 18-year term they should be able to sit on other Federal Courts until retirement, death, or removal.
