State Boundaries and Third States – Issue of Opposability. Remarks on the Polish-West German Normalization Treaty of 1970

The Western boundary of Poland was established by the Potsdam Agreement of 1945 and confirmed by the Boundary Agreement between Poland and the GDR of Gőrlitz of 1950. Poland exercised administration with respect to the adjudicated territories, but she made efforts to get the boundary recognized and confirmed by the FRG. This happened on the basis of the Warsaw Treaty of 1970. Boundary treaties are usually considered as objective regimes. It is disputable whether the Warsaw Treaty of 1970 can be classified as such a regime.
