Art. 56 OG; state liability for damage caused by officials in the exercise of non-commercial public functions is not governed by federal private law. The appeal jurisdiction of the Federal Court extends only to disputes concerning the application of federal civil law. Liability of a canton for acts of its officials in the performance of public duties is a matter reserved by Art. 76 OR to special legislation; it cannot be derived from Arts. 50 ff. OR. Where the claim rests on such public-law responsibility, the case is not amenable to federal appeal and the court must decline to enter into the matter (consid. 1).
