The late Chief justice of South Africa, Pius Langa, was a remarkable man. He achieved so much in his life and touched many people with his quiet dignity, his generosity and his sparkling humour. As a lawyer, he had a profound impact on the establishment of South Africa's new democracy and the adoption of the country's Constitution. Through his work on the Constitutional court, he charted a path that would allow the country to reach what he called the 'vision of the Constitution'. As a man, he served as an example to many: He was strong, committed, empathetic, thoughtful and kind. A transformative justice: Essays in honour of Pius Langa and Acta Juridica 2015 pay tribute to this remarkable man and lawyer. The book has three sections: first, a series of personal tributes to Justice Langa; second, reflections on the work of the Constitutional court under Langa's leadership as well as aspects of his philosophy as a judge; and third, explorations of a variety of specific themes in his judgments, writings and speeches. The contributions to A transformative justice are written by eminent judges, academics and practitioners, many of whom worked closely with Langa. The book addresses a broad range of practical and theoretical topics, including transformative constitutionalism, judicial dissent, the role of the people in constitutionalism, and legal education, as well as the areas of customary law, contract law, delict, administrative law, criminal law and procedure, and the protection of rights to equality, freedom of religion and culture.
