c. The county court shall have jurisdiction to hear and determine all appeals arising in the county in the following actions and proceedings: as of right, from a judgment or order of the district court or a town, village or city court which finally determines an action or proceeding and, as may be provided by law, from a judgment or order of any such court which does not finally determine an action or proceeding. The legislature may provide, in accordance with the provisions of section eight of this article, that any or all of such appeals be taken to an appellate term of the supreme court instead of the county court.
