Legal background Judicial measures
A number of provisions relate to judicial deployment:
	Deputy High Court Judges are appointed under section 9(4) of the Senior Courts Act 1981 following the recommendation of the Judicial Appointments Commission. Section 94AA of the Constitutional Reform Act 2005 sets out the circumstances under which, without such a recommendation, the Lord Chief Justice may appoint a person to sit as a Deputy High Court judge on a temporary basis where there is an immediate business need for a person to sit in the Crown Court or High Court.
Sections 4 to 6A of the Tribunal, Courts and Enforcement Act 2007 (the "TCEA 2007") provide who is to be a judge or other member of the FtT and UT. The list of judicial office holders who are also judges of both tribunals is contained in section 6 of that Act.
Section 22 of the Employment Tribunals Act 1996 makes provision for membership of the Employment Appeal Tribunal. Subsections (1) and (2A) set out a list of those judicial office holders who can be nominated by the Lord Chief Justice, after consulting the Lord Chancellor, to be a judge of that tribunal.
Section 93 of the Arbitration Act 1996 provides for judges of the Commercial Court and judges conducting official referee’s business (now dealt with by the Technology and Construction Court) to accept appointment, with the permission of the Lord Chief Justice of England and Wales, as judge-arbitrators.
Section 64 of the CA 2003 contains a power for the Lord Chancellor, with the concurrence of the Lord Chief Justice, to alter the name of specified judicial offices. That list included the office of the Registrar in Bankruptcy of the High Court which was recently changed by the Alteration of Judicial Titles (Registrar in Bankruptcy of the High Court) Order 2018 to "Judge of the Insolvency and Companies Court". The list of offices which can be amended does not include the offices of senior masters and registrars in the Senior Courts set out in section 89(3C) of the Senior Courts Act 1981, including the Senior Registrar in Bankruptcy of the High Court.
