The Legal Services Board (LSB) has brought in Field Fisher Waterhouse to replace Herbert Smith Freehills (HSF) as its adviser to defend the controversial Quality Assurance Scheme for Advocates (QASA) in a judicial review.

HSF was representing the LSB on the case, brought by the Criminal Bar Association (CBA) against the advocacy scheme, after the board approved the introduction of a grading system for advocates in the criminal courts.
