United States of America

As well as acting for international clients, law firms and General Counsel who send their work to him in England, Marc Beaumont offers advice in English commercial law and ADR having been admitted to the New York Bar (FLC) in January 2013.

Marc is now international counsel at Rivkin Law Group in Manhattan, New York City.

Marc’s role  provides UK clients with a service in the United States, whilst at the same time serving as a gateway to Europe for US companies and individuals.

Businesses, organisations and individuals in other countries may instruct Marc Beaumont directly to advise, to draft pleadings, written argument or transactional documents and to appear in Courts and Tribunals, or in Arbitrations or at Mediations, in a number of practice areas, including those set out below.

As a UK pioneer in direct access to the English Bar, direct client instruction is second nature so far as Marc is concerned (see Direct Access Barrister and biographical pages). He is widely credited with inventing the English scheme of domestic direct access now known as the Bar Public Access scheme. Marc is now operating this practice model internationally.

In-House and General Counsel thinking of using a UK law firm will access the same (or better) expertise by instructing Marc Beaumont directly to advise on English commercial law problems, but at lower cost, with fixed fees often the chosen payment model. In-House Counsel may also directly instruct Marc to act at Arbitrations and Mediations.

US Law Firms may instruct Marc Beaumont directly and without the intervention of a UK Solicitor under the English Bar’s International Practice Rules or under the Bar Direct Access scheme. Marc will travel overseas at short notice, subject to availability. Such direct instruction saves the (often very substantial) cost of an English law firm.

In many situations, it is not necessary to instruct Marc Beaumont from the USA via an English law firm, especially where such a firm would be little more than an expensive post box. The English tradition of referral to a Barrister and a Barrister’s high ethical standards, are such that a foreign law firm instructing Marc Beaumont on behalf of one of its clients will never be at risk of that client being “poached.”

Marc is willing to organise and “project-manage” work involving both foreign law firms and their English counterparts. He understands both the cultural similarities that unite and the differences that divide them. He is independent-minded and will not tolerate any unfair treatment of foreign law firms.

EU law

In 2013, Marc Beaumont acted in  Reg (Mehey et al) v Bar Standards Board [2013] 16th October, High Court, Lawtel 24.10.13. This was a judicial review arising from failures of due process in the English Bar’s disciplinary arrangements. Marc’s submission that Art. 47 of the EU Charter of Fundamental Rights now has direct effect in the UK, was accepted by the High Court.
