The Commissioner for Justice, Fundamental Rights and Citizenship is a post in the European Commission. The current commissioner is Viviane Reding.
The post was created in 2010 by splitting the previous Justice, Freedom and Security portfolio into a justice orientated post (the subject covered here) and a security orientated post: the Commissioner for Home Affairs. This split was made as a concession to the liberals in the European Parliament to gain their support for the second Barroso Commission.
