King Charles III made the appointment on the advice of the prime minister and lord chancellor, following the recommendations of an independent selection commission.

The commission consulted across each of the Supreme Court’s three UK jurisdictions before making its recommendations.

Welcoming the announcement, the president of the Supreme Court, Lord Reed of Allermuir, said: “I am delighted to welcome Lady Justice Simler as a Justice to the Supreme Court.

“She will bring exceptional experience and ability to the court following a distinguished career as a barrister and judge. Her experience in employment law, tax, public law and criminal law will be highly valuable to the Supreme Court and will further strengthen us as a world-leading court.”

Dame Ingrid Simler was called to the bar by Inner Temple in 1987, having read law at Cambridge University, and completed a post-graduate diploma in EU law at the Europa Institute, University of Amsterdam.

She practised at the bar at Devereux Chambers, where she became head of chambers before becoming a judge. She was appointed to the Attorney General’s Civil Panel A in 2001 and as junior counsel to the Inland Revenue (Common Law) in 2002. She took silk in 2006.

After various judicial appointments she was sworn in as a lady justice of the Court of Appeal in June 2019.

Lady Justice Simler is married with four children. This appointment follows the retirement of Lord Kitchin.
