We are delighted and proud to present this wonderful collection of essays marking Lady Hale’s retirement from the UK Supreme Court in 2020. Adding to the tributes paid to her by Lord Reed, Richard Atkins QC, Christina Blacklaws and Dinah Rose QC at the moving valedictory ceremony held at the Supreme Court in December 2019, these chapters, comprising a mix of academic appraisals and personal reflections, take stock of Hale’s remarkable career to date. No one would be so foolish as to imagine that her career has now come to an end. There will no doubt be further chapters to write as her formal judicial retirement in the UK is followed by numerous new projects, both local and international. In particular, as someone who has analysed the law as an academic, helped to develop legislation as a Law Commissioner, and interpreted and applied legislation and developed the common law as a judge, it is fitting that she should now contribute to the making of legislation as a member of the (parliamentary as opposed to judicial) House of Lords. But there is no doubt that her contributions as an academic, Law Commissioner and judge have been extraordinary, and it is those contributions that this volume records and celebrates.
