(1) The parties to the appeal proceedings shall be entitled to file an appeal on points of law.
(2) The appeal on points of law may be based only on the contention that the decision rests upon a violation of the law; Sections 546 and 547 of the German Code of Civil Procedure shall apply mutatis mutandis. The appeal on points of law cannot be based on the contention that the competition authority erroneously and in violation of Section 48 or Section 50(1) assumed it had jurisdiction.
(3) The appeal on points of law shall be filed in writing with the higher regional court within one month. The time period shall begin upon service of the decision being appealed.
(4) The appeal on points of law shall include a statement of reasons to be filed within two months from the service of the decision issued by the appellate court. The time limit may, upon application, be extended by the presiding judge. The statement of reasons shall include an explanation as to the extent to which the decision of the appellate court is being appealed and its modification or revocation is being sought. If leave to appeal on points of law was granted based on an appeal against refusal to grant leave to appeal, the statement of reasons for the appeal on points of law may refer to the statement of reasons for the appeal against refusal to grant leave to appeal.
(5) The appeal on points of law and the statement of reasons for the appeal must be signed by a lawyer admitted to practise before a German court; this shall not apply to appeals on points of law filed by the competition authorities.
(6) The Federal Court of Justice shall be bound by the findings as to the facts in the decision being appealed unless admissible and well-founded reasons for an appeal on points of law have been put forth in respect of these findings.
