Art. 59 and Art. 49(6) BV; church tax and enforcement of land-based tax claims against juristic persons. Art. 59 BV applies only to personal claims and does not prevent enforcement at the place where the encumbered immovable property is located. Tax claims attached to land are treated as real claims. Art. 49(6) BV, as a consequence of religious freedom and freedom of conscience, may be invoked only by natural persons capable of such rights; juristic persons, lacking conscience and religion, cannot rely on it. The fact that the levy is a ground tax does not exclude the constitutional issue, but it does not change the result (consid. 1-2).
