Human rights are the fundamental rights and freedoms to which every person is entitled in law, often relied on in litigation, advisory work and public decision-making. In the UK, many core civil and political rights are protected through the European Convention on Human Rights (ECHR), given effect domestically by the Human Rights Act 1998 (HRA). The HRA allows individuals in England and Wales, Scotland and Northern Ireland to enforce Convention rights against public authorities, and requires courts to interpret legislation compatibly with those rights so far as possible. In Ireland, human rights derive from the Constitution, the ECHR (incorporated by the European Convention on Human Rights Act 2003) and EU law, alongside international human rights treaties. Common issues include proportionality, positive obligations, horizontal effect, and the interplay between human rights, constitutional law, judicial review and data protection. Human rights arguments frequently arise in criminal law, immigration and asylum, policing, prisons, community care, mental health, equality and discrimination, freedom of expression, family law and public inquiries. Usage of “human rights” is broadly consistent across the UK and Ireland, though the constitutional framework, remedies and interpretative techniques differ by jurisdiction.
