The Current Legal Problems lecture series and annual volume was established around sixty years ago at the Faculty of Laws, University College London and has long been recognized as a major reference point for legal scholarship. The continuing strength of Current Legal Problems is its representation of a broad range of legal scholarship opinion, theory, methodology, and subject matter, with an emphasis upon contemporary developments of law. Contributions to the 61st volume in the series include an analysis of war as crime by Professor Gerry Simpson, an assessment of the problems in building a realistic climate change regime by Professor Daniel Cole, and an exploration of the problems of character evidence by Dr Mike Redmayne.
