Monckton’s Brexit & EU Relations Law Toolkit

The Brexit transition period has now ended, and the UK has begun its new relationship with the EU pursuant to the Withdrawal Agreement, the Trade and Cooperation Agreement and the various associated agreements and declarations. This represents a seismic change to both international and domestic laws. Barristers at Monckton Chambers have been at the forefront of advising on and litigating matters connected with Brexit since the referendum in 2016. Recognised as pre-eminent specialists in EU law, public and administrative law, commercial law and public international law, members of Monckton Chambers are well placed to advise and represent clients in relation to all areas connected with the UK’s new relationship with Europe – EU Relations Law.

To that end, Barristers of Monckton Chambers have founded a new EU Relations Law blog – available at – exploring all aspects of the UK’s new arrangements with the EU and their domestic implementation. A selection of blog posts and links to our relevant primary resources and videos from our recent seminar series in collaboration with the University of Cambridge can be found below in our Brexit and EU Relations Law Toolkit, to help you navigate the significant and legal changes applicable from January 2021:

·       is provided through a diverse set of practitioners

·       is appropriately funded

·       is responsive to defendant needs both now and, in the future,

·       contributes to the efficiency and effectiveness of the Criminal Justice System

·       is transparent

·       is resilient

·       is delivered in a way that provides value for money to the taxpayer.

Paul Harris QC is The Lawyer’s Barrister of the Week

The Lawyer has selected Paul Harris QC, who led for the claimants in Walter Hugh Merricks CBE v Mastercard Inc in £14bn Mastercard consumer claim which is now set to proceed after an historic Supreme Court ruling (see website news 11 December), as its “Barrister of the Week”.

The Lawyer heralds 2020 as “the most successful 12 months” of the Monckton Silk’s career, because Paul Harris “not only triumphed for his beloved football team but also for 46.2 million adults.” The football team is Manchester City which Harris represented back in June, in the Court of Arbitration for Sport (CAS), taking on UEFA in a bid to appeal a two-year ban from the Champions League. CAS overturned the previous decision and reduced Manchester City’s fine from £30m to £10m.

Harris admits of the Mastercard case that “To be the guy that sets the field in that core area of practice, that is really satisfying,” with the dam now bursting on the logjam of CPO applications. The Lawyer confirms that he is currently also involved in three other collective proceedings-type cases and he has already since been asked to do another.

“Barrister of the Week” is selected by The Lawyer’s Litigation Tracker team. Subscribers can access the full article here.

Anneli Howard – New Silk appointment

Monckton Chambers is delighted to announce that Anneli Howard will take silk in 2021.

Anneli Howard is recognised by the legal directories in six different disciplines: Competition, EU law, Consumer law, Public Administrative law, Aviation and Telecommunications. In 2018 Anneli won The Legal 500 award for EU/Competition Junior of the Year and was one of the Lawyer’s “Hot 100” in 2016. As a Junior she was a member of the AG A panel for Public Administrative law and WTO/International Trade.

The members and staff of Chambers warmly congratulate Anneli on her appointment to Queen’s Counsel.

The new status for all 116 new QCs will be effective from March 2021.

The full list of QC appointments, announced on the17 December, can be viewed on the QCA website.

Philip Moser QC and Anneli Howard to chair Bar Council EU Committee

At the last meeting of the Bar Council this year, held virtually on 14th December 2020, Philip Moser QC of Monckton Chambers was elected as Co-Chair of the Bar Council EU Law Committee and Anneli Howard of Monckton Chambers was elected as Vice-Chair, both from 1st January 2021.

The EU Law Committee monitors and addresses legal issues emanating from the European Union including policy and legislative proposals from the EU institutions, and its remit will now include the Withdrawal Agreement, future UK-EU relations law and the (still awaited) outcome of the trade deal negotiations, in what promises to be an eventful and busy year for the profession, its regulator and its clients.

Alan Bates appointed to Human Rights Act expert review

Monckton barrister Alan Bates has been appointed by the Lord Chancellor as a member of the independent expert review of the Human Rights Act (HRA).

The Review, which was announced today by the Lord Chancellor, will be chaired by former Lord Justice of Appeal Sir Peter Gross. Its task will be to review how the HRA is being interpreted and applied in the courts, and to make recommendations as to whether any legislative or other changes are needed. Its terms of reference do not call into question the United Kingdom’s continuing to be a party to the European Convention on Human Rights.

Alan brings to the Review his specialist knowledge of EU law. He has represented the United Kingdom – and also the European Commission – in cases in the EU Courts. Prior to coming to the Bar, he worked on an audit by the Law Commission of the compatibility of the English law of bail with the HRA.

Commenting on his appointment, Alan stated: “The UK’s future relationship with the EU interacts in multiple ways with the mechanisms for the protection of individuals’ ECHR rights. I am looking forward to working with Sir Peter Gross and the other members of the Review, which will be independent of Government and will approach all questions with open minds.”

The other members of the review are former Law Society President Simon Davis, Professor Maria Cahill, Lisa Giovannetti QC, Sir Stephen Laws QC, Professor Tom Mullen, and Baroness Nuala O’Loan.
