Today, the European Court of European Rights held that it was a violation of the European Convention on Human Rights when Germany seized property from its citizens in the east after reunification in 1990. (Via Expatica)
This decision relates to land awarded to east Germans after 1945. A later decision will deal with land seized between 1945 and 1949, before the GDR came into existence and effectively under Soviet control.
In 1992, Germany expropriated the land without compensation. Up to 70,000 former GDR citizens are affected.
