Hello. I am a recent graduate of Environmental Sciences in Canada. I do understand that the majority of students entering the Masters Law programs in Europe have bachelor law degrees. Are the programs restricted to only these individuals? I hold a baccalaureate in Science (Environmental) with a specialization in Natural Resource Management. Is there an option for those prospective Masters students without prior substantial law experience? What are my options? I am very interested in European Union Environmental Laws and would like to practice law in Europe in the future (as I am also a citizen of Poland). Perhaps I need to take a different route other than the M.LL.? What porgrams are there in Europe for people with Bachelor degrees wanting to study law in Europe?

see Utrecht University (international masters programs section - all masters in law programs are there), Leiden University, and Katholike Universiteit Leuven. It is Utrecht University which is the most prestigious among them.
For the extremely expensive schools- Oxford, London School of Science and Economics, University College London, etc.
I am sorry I am busy with work at the moment. If I had more time, I would have had provided the links for you. Good luck !
