Leading European human rights lawyers and political scientists are set to debate challenges to international law at a conference in Belfast.
Experts from Canada, US and Germany will be at Queen's
The experts will be exploring recent difficulties facing international law and human rights in global politics.
Academics from Queen's University will also take part in the conference - Global Norms under Siege.
Speakers include lawyer Wolfgang Kaleck who filed for criminal indictment against the US Secretary of Defence.
The case against Donald Rumsfeld and others was for alleged war crimes perpetrated against Iraqi detainees at the Abu Ghraib Detention Centre.
The event has been organised by Professor Antje Wiener of the Jean Monnet Centre of Excellence and Professor Colin Harvey of the School of Law.
Professor Wiener said experts from Canada, the US, Germany and the UK would debate how individual countries react to crisis situations in international law.
"The discussions will focus on the implementation and contested interpretation of human rights norms, the principle of non-intervention and the UN Convention against Torture," he said.
"This represents a strong working group of internationally-respected academics within the Schools of Law and Politics and International Studies who together offer expertise on most regions of the world."
