A human rights body that rebuked Poland last week over moves that hobble the Constitutional Tribunal plans to investigate a new police surveillance law passed by the country's new conservative ruling party.

Panos Kakaviatos, a spokesman for the Council of Europe human rights group, said the Venice Commission, an advisory body made up of legal experts, will study the surveillance law passed in December and issue its opinion during a June 10-11 session.

That law expands the government's access to Internet data and gives police and the secret services greater spying powers. It is one of several new laws that have alarmed domestic critics and the European Union.

Last week, the Venice Commission said new laws regulating the constitutional court undermine democracy, human rights and the rule of law.
