specialist dispute-prevention advice, such IR35 tax- and commercial risk management; remediation through disclosures where issues have arisen; advice and representation during HMRC enquiries, investigations, reclaims or clearance applications; tax litigation through the tribunals and courts, from the First-tier Tribunal (Tax Chamber), to the Upper Tribunal, Court of Appeal and Supreme Court; a broad range of strategic tax dispute solutions such as group litigation, tax judicial review, restitution claims, other commercial claims, influencing at policy level, advice on confidentiality and privilege including cross-border matters, and strategic advice and coordination of international proceedings and procedures (EU Court of Justice, Mutual Assistance Procedure, foreign litigation etc.).
