Mark graduated from the Law School in 1984. He qualified as a solicitor and has worked in the fields of business/corporate tax in the City, mainly as a partner in Macfarlanes, throughout his career until his retirement shortly after a “landmark” birthday in 2023.
For a number of years before his retirement he was the Chair of the Taxation Committee of the British Venture Capital and Private Equity Association. He returned to Durham for the Michaelmas Term 2019 to start work on a textbook on the taxation of partnerships and private capital structures he co-authors with another Macfarlanes partner. The (850-page) second edition was published in the Autumn of 2024, just in time to be rendered partially obsolete by the new government’s first Budget. Mark was appointed as a fee-paid judge of the Upper Tribunal in 2022 and sits on financial services and tax cases in that tribunal and tax cases in the First-tier Tribunal.
