In English and European law, proportionality is a principle requiring that legal measures, restrictions, or decisions do not exceed what is necessary to achieve a legitimate objective. It ensures a fair balance between individual rights and the aims pursued by public authorities.
Proportionality asks whether a measure is suitable, necessary, and balanced in achieving its purpose. It prevents excessive or unjustified interference with rights, especially in constitutional and human rights contexts.
Often applied in judicial review, human rights claims under the Human Rights Act 1998, and EU law cases to assess whether state actions unjustifiably restrict fundamental freedoms.
Proportionality provides a structured framework for balancing competing interests, promoting fairness, and ensuring government measures remain within reasonable limits of legal authority.
