In the field of law the institute's focus is on comparative and international law, particularly public international law and human rights.

Concerning comparative law the research focuses on the major legal systems of the world and thus avoids the discipline's rightly criticized Eurocentric approach. In doing so the spotlight is on the history and cultural background of the various legal systems, including religion, beliefs, philosophy, language, and cross-cultural influences. Due to both subjective and objective reasons, the legal systems of the Middle East, i.e. Islamic, Jewish and Persian law are extensively dealt with, but Indian and Chinese legal traditions receive their due share as well. The results of the research also enter university education with a course dedicated to comparative law in the BA program, for which a university textbook was also written in Hungarian for free download from the institute's homepage. The latest publication in comparative law is János Jany's book, published by Ashgate in 2012, about the interactions between Islamic, Jewish, and Zoroastrian law.

Concerning public international law research interests include the reform of the Security Council; the application of rules of international law in domestic law, especially in connectionwith the publication of the resolutions of the Security Council; the various topics of non-intervention and prohibition of use of force. Particular research focuses on the problem of maritime violence (armed robbery and piracy), and the operational aspects of a possible legal forum competent in the crimes of maritime violence (jurisdiction, the operational costs, and the considerations of human rights). Questions of human rights are dealt with along the lines of both international law and the ethical issues in the international relations. Similarly to comparative law, human rights are also studied through the lenses of culture and the influence of various civilizations. Therefore the evolution of the regional human rights systems, the influence of the civilizations and the effect and role of culture in the international political andeconomic relations are research areas of paramount importance.
