This is a landmark and ambitious research project looking at private law through the policy prism undertaken by a team of acknowledged experts in their fields. The majority of existing literature diminishes the impact of policy in the development of legal principles, impeding a deeper understanding of it. Part of a two-part study, this first volume explores tort law, property law and equity. Both studies engage with modern challenges and technical developments that now inform private law, with chapters looking at the Grenfell disaster, compensation of medical injuries post COVID-19, the gig economy and co-ownership. They also explore traditional private law areas through a novel lens, such as psychological injury and the impact of fairness and/or equality obligations. They highlight the similarities and differences across many aspects of private law, allowing for a richer analysis across all the strands of private law.
