In December 1979 PPSP, Choros and AAPSE joined forces to combat "Law 815". Together they gained majorities at various student assemblies around the country. The assemblies voted to occupy university departments in Athens, Thessaloniki, Ioannina, Patras and Rethymno. After the protests had subdued the Greek government withdrew the law.Papadogiannis, Nikolaos.
