1. The state court could only either find the arbitration award enforceable in its entirety or refuse to find the award enforceable also in its entirety, as it is not the place of the state court in considering a case seeking recognition of an arbitration award as enforceable to review which of the reasons behind the award are justified or unjustified, or which item in an accounting was proved or acknowledged by a party, or to enter at all into consideration of the merits of the dispute.
2. The arbitration court may apply § 319 of the [former German] Civil Procedure Code, i.e. correct obvious errors of calculation, typographical errors or the like. It may not, however, amend its material content after service of the award on the parties, unless both parties consent to such amendment.
3. Resignation of appointment is a declaration by arbitrators that they refuse to perform their duties, that they renounce the agreement with the parties obliging them to resolve the dispute.
4. In light of the declaration by the arbitrators in the presence of the parties that they resign their appointments, and thus renounce the agreement to perform the duty of arbitrators, pursuant to § 1033 of the [former German] Civil Procedure Code the arbitration agreement ceased to be in force, and expired.
5. In light of expiration of the arbitration agreement, the arbitrators who resigned their appointments had no legal basis to take up their rights and obligations again upon the unilateral request of the plaintiff without the consent of the defendant, as they did.
