The elections held in September 2021 for the Berlin Abgeordnetenhaus, the state parliament, were marred by administrative problems at nearly a tenth of polling stations. There were shortages of ballot papers, unusually long queues to vote and ballots delivered to the wrong locations. Some voters were turned away, or offered only ballot papers for the federal elections taking place the same day (in which Olaf Scholz was elected as chancellor). After a long investigation, the state constitutional court ruled last November that the state election would have to be repeated. The date was set for 12 February.
