Constitutional Blocking Minority (Sperrminorität)

In German state constitutions, certain pivotal actions require a two-thirds supermajority (66.7%) of parliament. Any single party or faction holding more than one-third (>33.3%) of all seats holds a Sperrminorität.

  • Veto appointment of state constitutional court judges (Verfassungsrichter)
  • Block amendments to the state constitution
  • Prevent premature dissolution of parliament for snap elections
  • Freeze court governance even while completely excluded from government
Warning: AfD controls 32 of 88 seats (36.4%), which exceeds the 30-seat threshold. The party holds an absolute constitutional veto.
