A German civil court usually does not announce its judgment at the end of the hearing. It sets a separate date for that. Under § 310 of the Code of Civil Procedure, the date may be more than three weeks away only for important reasons, especially the size or difficulty of the case.
A judgment announced right after the hearing has its own name, the Stuhlurteil, the chair judgment. In civil cases the separate date is weit häufiger, far more common. In criminal trials, the judgment at the end of the main hearing is the rule.
