Kernrechtsfrage
Whether the appellate judgment was rendered by a lawfully constituted court under Art. 30(1) BV.
Extrahierter Entscheid
The panel was unlawfully composed because two judges had already left office when the collegiate court delivered judgment.
Extrahierte Begründung
Under Art. 30(1) BV, parties are entitled to the proper composition of the court. Only the composition at the time of judgment matters; prior consent to a draft is irrelevant. Since the two judges' terms had expired by 4 January 2010, they could no longer validly act as judges.
