In Redfearn v UK the European Court of Human Rights examined the question whether dismissal for membership of a political party is compatible with freedom of association under Article 11 of the European Convention on Human Rights. The Court endorsed a strong commitment to multi-party democracy and protection of employees against the domination of the employers. This note discusses the judgment and its implications for UK law, looking at three key issues: first, whether the law of unfair dismissal provides effective protection against action that poses a threat to the enjoyment of Convention rights, second, the grounds under which an employer may justify the lawfulness of a dismissal that interferes with a Convention right, third, the available remedies against the employer when there is a breach of a Convention right.
