Art. 79 OG in connection with Art. 56, 57 and 59 OG; appealability and value in dispute in an ownership claim against attachment; claims concerning seized real estate governed exclusively by cantonal law are not cognizable by federal appeal, and their value cannot be included in the Streitwert for appealable movables. For the minimum value, only the objectively appraised value of the appealable предметs counts; non-appealable claims are excluded from the computation. The Federal Supreme Court examines ex officio whether the appeal conditions are met (consid. 2).
