The ruling Socialist Party has called on the police to prevent a march planned by neo-Nazi groups to mark the death anniversary of Nazi leader Rudolf Hess, Socialist MP Gergely Barandy told MTI on Tuesday.

On basis of international agreements Hungary's law enforcement bodies could ban fascist events, Barandy said. He added that the police should make a straightforward reference to those agreements rather than use a hollow pretext for the ban such as the march's causing traffic disturbances.

Laszlo Velki, an expert on international law, told MTI earlier that international agreements such as the European Convention on Human Rights (1950), or the Paris Peace Treaties (1947) allowed signatories to restrict the freedom of expression and assembly in order to protect the rights and interests of other groups of citizens, and stipulated that organisations aimed at depriving people of democratic rights should be banned.

The expert added, however, that though Hungary was signatory to those agreements, it was not easy to enforce them as their restrictions had not been fully incorporated in Hungarian legislation.
