The Constitutional Affairs Group of the Society of Labour Lawyers advocated for a career judiciary way back in their response to the DCA Consultation on Judicial Diversity in 2005. It is good to see that 9 years on Lord Neuberger is promoting the issue. It is not about quota's or being PC it is about the community having faith in the justice system and justice being dispensed by a group of people who reflect the community they serve.
If you would like a copy of that response let me know.
