Within: Company and partnership

Maitland Chambers is ‘a top class’ commercial Chancery set backed up by a group of ‘brilliant’ clerks. A deputy High Court judge in the Queen’s Bench and Chancery Divisions, Catherine Newman is a stand-out practitioner for company and partnership matters. She successfully defended the directors of Destiny Investments against a hostile minority shareholders’ petition in Destiny Investments Limited and others v TH Holdings and others. David Mumford acted for the defendant in BAT v Sequana, successfully resisting all but one of the claims. Jonathan Russen QC left chambers in August 2017, following his appointment as a Specialist Civil Circuit Judge, while Anthony Trace QC moved to 4 Pump Court.
