Mandates for German Members of Parliament are reduced to 2 legislative periods for both the German state and federal parliaments as part of the parliamentary lifetimes. This rule is to be applied retrospectively for the 2 preceding legislative periods.
Elected representatives should not stick to their mandate, but rather make way for the intellectual capacity of others to bring new ideas into parliament. The fight to preserve the seat of deputy, and therefore susceptibility to corruption only to retain the position, no longer applies.
