A 1963 joint ownership bylaws contained arbitration clause for disputes between the co-owners. However, the Court held that although the Act on Co-ownership of Real Estate dated 28 June 1938 provided for the possibility to include this type of clause in the bylaws, the Co-ownership Act of 10 July 1965 did not adopt these provisions. Moreover, it is well established that arbitration clauses included in co-ownership bylaws drafted before the enactment of the 1965 Act are without effect.
