In the doctrine of law there were framed numerous and slightly different definitions of ownership. Most of them, however, emphasise the dominant role of the owner’s unlimited and exclusive power over a thing (or value) as well as his (her) dominat role to explore possibilities of legal and factual disposal. The Constitution of Poland of 1997 deals with the ownership (property) rights twice: in article 21 (within the basic constitutional regulations) and, even more detaily, in article 64 (1–3), in Chapter II of the Constitution, dealing with the civil fredoms and rights of entity. The central issue under the author’s consideration should be framed in a question: to which extend the limitations pointed in article 31(3) of the Constitution may define exploration of the owner’s rights and powers protected by the Constitution, in particular; by its provisions framed in its articles 21 and 64?
