The logic of respect for human rights and democratic values contributing to the political and economic stability of current and prospective European Union (EU) member states is irresistible. In the context of EU enlargement, the dominating theme is of candidate states striving towards and achieving the Copenhagen political criteria for membership. The 'political criteria' for accession require candidate countries to demonstrate 'stability of institutions guaranteeing democracy, the rule of law, human rights and respect for and protection of minorities'. Analysis of the UK domestic experience in attempting to uphold human rights in the context of the fight against terrorism affords some interesting perspectives on the impact of human rights on security issues. The European Constitution, if adopted, would provide the basis for the EU's accession to the European Convention on Human Rights (ECHR).
