Oder–Neisse line
Based upon this interpretation of the Potsdam Agreement, the CDU controlled German government maintained that the Oder–Neisse line was completely unacceptable and subject to negotiation. Also the Social Democrats of the SPD initially refused to accept the Oder–Neisse line. Thus, the official German government position on the status of areas vacated by settled German communities east of the Oder–Neisse rivers was that the areas were "temporarily under Polish (or [Soviet]) administration."
