Rights to health, food, and shelter have been litigated in various countries since the 1990s. Social and economic rights cases are a subset of public law litigation, subject to the same limitations. Social and economic rights litigation is not fundamentally different from other attempts at social reform through legal channels. It aims to unsettle entrenched institutional behavior for public benefit. Such cases call upon judges to perform familiar tasks, like reasonableness review, and are linked to public law theory and socioeconomic rights enforcement.
