Group actions

Monckton Chambers is in the vanguard of collective proceedings and class action litigation. Its members’ unparalleled experience, across a range of different jurisdictions, makes them the stand-out choice for any party involved in group litigation.

Commercial & regulatory JR

Judicial review with a commercial or regulatory element is at the heart of Monckton’s Administrative and Public law specialism. The rare combination of commercial and public law expertise on offer at Monckton means our members have a leading reputation and act in the most complex and high-profile challenges.

Our members accept instructions to provide advice and representation across the range of regulated sectors. They are regularly instructed in judicial reviews relating to:

Our practitioners work on behalf of both claimants and defendants, acting for companies, regulators and affected third parties to ensure their clients’ rights and interests are protected. A large number of our members are appointed to the Attorney General’s ‘A’, ‘B’, ‘C’ and ‘PIL’ Panel of Counsel, from which they represent clients including Secretaries of State and central government agencies in challenges to their decisions (click here to see panel members).

Members of this practice group are able to bring to their commercial and regulatory work their expertise in related areas of law including consumer law, competition, data protection, human rights, EU law and EU Relations law, public procurement, tax and duties.

State aid

Monckton Chambers is widely recognised as a pre-eminent set in the field of State aid law. We have experience of representing claimants and defendants in proceedings before domestic courts and tribunals in which an allegation of unlawful State aid has been made, as well as of acting for both complainants and respondents in EU State aid investigations, and in challenges to Commission decisions before the Community Courts.

Members are regularly instructed to advise potential aid recipients, their competitors, and government bodies on the lawfulness of proposed financial and other measures raising State aid concerns.

Our members’ expertise in procurement, local government, public and tax law makes them ideally placed to advise on State aid issues arising in the contexts of procurement, taxation and regulation. Other contexts in which our members are frequently instructed on State aid matters include media/broadcasting, regeneration schemes, infrastructure projects, public-private partnerships, rescue and restructuring aid, environmental measures, and financial services.

Members write regularly on State aid law in the European State Aid Law Quarterly and other legal journals, while Monckton practitioners are the authors of chapters on State aid in: Bellamy & Child, European Community Law of Competition; Korah, Competition Law of the European Community (LexisNexis); and Bacon, European Union law of State aid.

Members have also given oral and written evidence to various House of Lords and House of Commons Select Committees on State aid issues.

Fast track competition claims

Monckton Chambers has unrivalled expertise in the fast track procedure for competition claims before the Competition Appeal Tribunal. Barristers from Monckton Chambers represented both parties in the only fast track claim to have proceeded to trial to date. You can read news items about the case here, and a case note discussing the judgment here.

The fast track is designed to offer a fast and cost-effective way for victims of competition law infringements to bring their claims to court. Specifically the fast track guarantees that:

  • The hearing will take place within six months; and
  • The costs are capped, so the exposure to paying the other side’s costs is limited.

The Tribunal decides which claims are suitable for fast track. A claim is more likely to be considered suitable if:

  • The claimant is a small business;
  • The claim is relatively simple; and or
  • The claim does not require extensive disclosure of documents, or a large number of witnesses.

A claimant might ask the Tribunal for an order that the anti-competitive behaviour must stop, or for compensation for losses it has suffered as a result of it.

Public international law, WTO & investment treaties

Public international law

This is a fast growing area of practice within Monckton Chambers.

Members’ practice focus on the issues arising out of Brexit as well as human rights, EU and public law cases. International economic law, consisting of WTO law, sanctions issues, and bilateral investment treaty arbitrations is also a core part of Monckton’s public international law practice. Members of Chambers have also served as members of ICSID tribunals, WTO dispute resolution panels and the WTO’s Appellate Body.

WTO law

Effective WTO advocacy requires, in addition to a comprehensive knowledge of WTO law, an understanding of the multilateral institutional context in which WTO dispute settlement occurs, the ability to devise effective strategies within a system that does not allow for monetary or retrospective remedies, and the capacity to present arguments in a manner which WTO adjudicators (who are drawn from a wide variety of professional backgrounds and legal cultures) will find convincing.

Our members can offer this combination of expertise.

Members of Chambers have acted in numerous WTO disputes for a broad range of government and corporate clients. We often work directly with inter-agency teams created by our government clients as well as with representatives of industry.

We can advise on and act in every type of WTO case, including those involving:

  • General Agreement on Trade in Services (GATS) commitments;
  • Sanitary and Phytosanitary (SPS) issues and Technical Barriers to the Trade (TBT) issues;
  • Subsidies; and
  • Trade remedies (anti-dumping, countervailing duties and safeguards).

Investment protection treaties

We regularly advise on and act in disputes arising under bilateral investment treaties (BITs) and multilateral investment treaties (such as the Energy Charter Treaty and NAFTA).

We offer a combination of:

  • high-quality advocacy;
  • assured handling of the procedural and evidentiary issues which arise in ICSID and ad-hoc arbitrations; and
  • a strong understanding of public international law standards relating to the treatment of foreign investment.

We are also able to draw on our expertise in related areas such as EU law, international human rights law and (domestic) public law relating to economic regulation to develop sophisticated arguments and case strategies for our clients.
