Constantine Law Limited boasts a particular strength in handling internal investigations and disciplinary proceedings involving both FCA and PRA exposure and non-financial misconduct, regularly working closely with the firm's employment law team. The group is led by Sarah Wallace, a ‘brilliant strategist and excellent all-around lawyer’ who works with various senior executives and firms involved in FCA, SFO, and DOJ investigations. Wallace is especially noted for her defence-side work in complex enforcement actions, including LIBOR and insider dealing cases. The team was strengthened by the arrival of John Milner in March 2025.
