Mayer Brown International LLP’s Ian McDonald >acts for banks and funds, particularly in high-value disputes relating to loan structures, structured finance and derivatives, many of which have cross-jurisdictional elements. McDonald 'has great legal judgement and commercial acumen, and is a real team player who at the same time knows how to lead a team'. Other highly regarded advisers include David Allen, who has particular experience in banking and insolvency litigation, including several high-profile insolvency proceedings; Alistair Graham, noted for regulatory and fraud investigations, white-collar work and international asset tracing; and Susan Rosser, who acts in disputes involving complex financial products, regulatory investigations and enforcement as well as professional discipline, corporate investigations (including fraud and corruption), and professional negligence claims. The practice represented UBS in long-running litigation in London against Kommunale Wasserwerke Leipzig, which provides fresh and wastewater services to the City of Leipzig and surrounding area; the litigation, which went to the Supreme Court, involved claims for approximately $320m arising from the enforcement of various structured finance transactions.

Within: Commercial litigation

Mayer Brown International LLP's 'clients cannot speak highly enough of its efficiency, commitment and professionalism'. Stuart Pickford, who is 'an extremely bright, personable litigator whose calm demeanour and insightful analysis are an invaluable contribution', led advice to hotelier, Chen Mei Huan, in a long-running dispute concerning the ownership of shares in a BVI holding company, which (via a Macanese subsidiary) owns the Beijing Imperial Palace Hotel in Macau; the team's role included successfully advising on an appeal to the Privy Council, which set aside a decision of the Eastern Caribbean Supreme Court and ordered a retrial in the BVI. Ian McDonald heads the litigation and dispute resolution practice in London; Alistair Graham is 'one of the best commercial litigators around'; and Miles Robinson acts across a range of sectors, including energy, manufacturing, music, automotive, chemicals and outsourcing. Mark Stefanini and David Allen are also highly rated.

Corporate restructuring and insolvency

Within: Corporate restructuring and insolvency

Able to tap into the firm’s widespread network of international offices - most importantly in the US - and thereby allowing a degree of flexibility regarding the potential use of insolvency procedures including Chapter 11, Mayer Brown International LLP 's six-partner London team provides a 'very responsive service’ on contentious and non-contentious matters to a wide array of stakeholders. As part of her broad-ranging practice, the 'technically strong and extremely personable' team head Devi Shah has niche expertise at handling pensions-related insolvency matters; she recently advised the Pension Protection Fund in relation to the restructuring of the Hoover/Candy group's pension liabilities. Shah is also noted for her prowess at handling restructurings within the insurance sector and recently worked with the provisional liquidators, creditors and regulatory authorities to put together a novel solution for the closure of a Lloyd's corporate member, ACAL Underwriting Limited (in provisional liquidation). David Allen handles contentious insolvency work for banks, IPs and corporate trustees. Newly promoted partner Jessica Walker is also recommended.
