Successful initiatives were thus quite rare, with a gap of 20 years during 1929–1949, and even of more than 30 years during 1949–1982 during which not a single initiative found favour with the electorate. In the 21st century, the picture changes significantly, with five successful initiatives during the 2000s, and another five just during 2010–2014. Among the 170 rejected initiatives (as of October 2014), there are several that still played a major role in Swiss politics. Notable among them, also for the high voter turnout they inspired, were the anti-immigration initiatives of James Schwarzenbach in 1970 and 1974 (74.7% and 70.3% turnout, respectively), and the 1989 initiative with the aim of abolishing the Swiss Army (69.2% turnout). At the time of its introduction to the Swiss Constitution in 1891, the federal initiative system was initially meant to let groups that were not represented in the parliamentary process voice their concerns. Since the 2000s, it has been increasingly used by political parties to bypass the parliamentary process. Some critics argue that it undermines the whole Swiss political system, based on compromise and adaptation to one another, as it suppresses any possibility to negotiate on an issue (an initiative can only be accepted or rejected as a whole). Others argue that it is democracy in its purest form. Critics also argue that the multiplication of initiatives undermines the stability of the legal framework, as initiatives proposing drastic reforms are more and more frequent.
