Published: 17th March 2026 Drawing on five years of collaboration, this report explores a programme led by Public Law Project with community groups and frontline organisations to advance shared legal approaches for social change. Authored by Professor Jacqueline Kinghan and Professor Lisa Vanhala. Read the report Using public law to tackle unfair systems can bring transformative and tangible change. Yet it’s complex, takes time and resources, and risks being counterproductive when not done well. In 2017, PLP partnered with the Lankelly Chase Foundation to gain a better, more rigorous understanding of the conditions that are necessary for successful public law-oriented collaborations and subsequent system change. The partnership aimed to use PLP’s public law expertise to support a group of frontline charities and NGOs across wide ranging areas, including criminal justice, welfare benefits, discrimination, domestic abuse and child protection. PLP’s lawyers worked closely with organisational leaders, advocacy workers, community groups and frontline advisers to provide in-depth training and support, identify public law issues and support routes to challenge. Learning was central throughout. Together, PLP and the Lankelly Chase Foundation explored when and how legal approaches can support systemic change, and what role public law — through judicial review, litigation and other strategies — can play in making that change happen. Victoria Pogge von Strandmann, Legal Director at PLP, said: “This report offers a unique perspective and detailed insights for organisational leaders, advocacy workers, community groups, frontline advisers and second tier advice organisations on how to build successful partnerships that build confidence in using public law to challenge injustice and achieve systemic change.” Webinar PLP held a free webinar in conjunction with the launch of this report, where key learnings were discussed.
