Our former colleague, Professor Stephen Livingstone, made a huge and special contribution to the Northern Ireland Legal Quarterly. To commemorate and celebrate Professor Livingstone’s contribution, here, for the first time, we collect several of his main articles from our journal. The publication of this special issue is timed to occur with the 2019 Livingstone Lecture, which will take place on Thursday 21 November 2019. The special issue is available open access. We hope this special issue will become a key reference point for future scholarship, extend the influence of Professor Livingstone’s scholarship, and continue to reflect our thanks to him, far into the future.
