European Union advisers are in Hungary for talks on a new constitution which has been criticized by human rights groups for outlawing gay marriage and limiting civil liberties.
Members of the Venice Commission, the Council of Europe's advisory body on constitutional matters, were meeting Tuesday with government, opposition and judiciary officials.
Commission secretary Thomas Markert said the group was gathering information about how the new law will affect, among other issues, the state budget and the status of millions of ethnic Hungarians in neighboring countries
The new constitution which will take effect next January has been criticized by human rights groups.
It was solely approved by lawmakers from government parties led by Prime Minister Viktor Orban.
