Margin of appreciation
A doctrine giving public authorities a degree of discretion when courts review choices involving policy, expertise, local conditions, or rights balancing.
The margin of appreciation describes judicial restraint where elected bodies or specialised authorities are better placed to assess social needs, technical facts, or competing interests. It is well known in European human rights law, where national authorities may receive latitude, especially on moral, social, or institutional questions. In Swiss law similar ideas appear as administrative discretion, autonomy of cantons and communes, and deferential review of complex policy choices. The margin is not unlimited: legality, equality, proportionality, and core rights still require effective judicial scrutiny.
