A user is preparing to file a complaint with the Bar Council against an advocate who sent a legal notice for an exorbitant amount based on an old, likely time-barred claim. The user has already replied to the notice without response and anticipates several defences from the advocate, including good faith, reliance on client instructions, ambiguity in rules, and lack of precedent for penalties. They are seeking advice on how to effectively counter these anticipated defences and strengthen their complaint.
