Polish officials are trying to prove to the members of an international human rights commission that recent changes to the Constitutional Tribunal are in line with the Polish constitution and European Union standards.

Members of the Venice Commission, a constitutional watchdog, are holding two days of meetings in Warsaw starting on Monday. The head of the commission, Gianni Buquicchio, is starting off by meeting Polish President Andrzej Duda.

The Polish government requested the review late last year after new laws regulating the constitutional court sparked street protests and the concerns of the European Union.

The Venice Commission is part of the human rights body the Council of Europe. Its findings, which are expected in a few weeks, are not binding.
