This volume originates from the fourth Public Law Conference, held in Dublin in 2022.Leading scholars and judges from across the common law world presented papers on the making (and re-making) of public law across country studies, historical studies and studies of contemporary and future issues. The book has three broad categories of contribution: country studies which consider the evolution of public law within a particular jurisdictional context; historical studies, which shed light on the foundations of public law; and studies of contemporary and future issues, namely populism, COVID-19, protection of Indigenous peoples, and the public – private divide.
