THE FIRM:

Edmonds Marshall McMahon is the first and only specialist private prosecution firm in the UK. The firm’s experience, expertise and contacts in the criminal justice system are unrivalled. Edmonds Marshall McMahon prosecutes a wide range of offences, and advises Governments, companies, charities, individuals and NGO's with fraud, corruption and complex criminal issues, supervising investigations, and assisting law enforcement both nationally and internationally.

The firm’s success thus far has been created by a private, high-powered team of senior prosecutors with an unrivalled track record in conducting major fraud prosecutions and regulatory work. The criminal side of the firm is staffed by highly experienced prosecutors and investigators and offers tailor-made prosecution services, from advice and investigation through to criminal proceedings and confiscation and enforcement.

In 2015, the firm decided that the best course of action for victims would be to have all possible legal options under one roof. In 2016, EMM created its civil fraud team. The firm is now, more so than any other firm in the UK, able to provide a total solution to fraud: the firm can advise clients on the best means of retrieving assets in frauds that are linked to the UK, whether by civil asset retrieval or criminal confiscation order and conduct specialist investigations in-house.


PRINCIPAL AREAS OF WORK:


Fraud Prosecution:

Since inception, Edmonds Marshall McMahon’s focus has been on assisting companies or individuals that have been the victims of complex fraud. The firm assists in either recovering money or privately prosecuting and deterring fraudsters. The firm commonly deals with fraud in joint venture contracts; fraud in commercial contracts with banks and financial institutions; theft, fraud, dishonesty or money laundering; loan, insurance and mortgage fraud; data theft by employees and internal fraud.


Bribery & Corruption:

Edmonds Marshall McMahon has one of the largest dual investigative and prosecutorial teams in a private firm in the UK. Many of its members are former senior SFO investigators and prosecutors who undertake corruption investigations all around the world on behalf of clients, including for States.


Counterfeit Prosecutions:

The increase in counterfeiting has staggering financial implications for businesses; all companies with a brand to protect must seriously consider this growing market. Edmonds Marshall McMahon’s unique service means the firm will investigate (or work with investigators), advise, prosecute and robustly enforce any compensation and/or confiscation order for its clients, ensuring compensation for them.


Advisory & Regulatory:

All directors of Edmonds Marshall McMahon have extensive experience in the area of regulatory law, having advised and prosecuted for the Medicines and Healthcare Products Regulatory Agency (MHRA), Department for Food, Environment and Rural Affairs (DEFRA), Health and Safety Executive (HSE) and the Environment Agency. The firm has also advised pharmaceutical companies and medical device manufacturers on the medicines and medical devices licensing regime. The background of the firm’s directors and senior lawyers enables the firm to give comprehensive, commercial and relevant advice.


Civil Fraud Litigation:

Our team of civil fraud lawyers are genuine experts in their field with a wealth of hard-earned experience of litigating complex and heavyweight cases against the toughest of opposition. Within our fraud team, we have lawyers who have trained and worked in some of the leading domestic and international law firms. But in addition, we also have our own in-house team of specialist fraud investigators and prosecutors, who have enjoyed former careers with the SFO, the FCA, the Police and the criminal bar, and who are adept at breaking down complex frauds and corporate structures and devising recovery strategies.

We believe that the depth of our in-house civil fraud experience and capability gives us a unique advantage over our opponents and other firms operating in our space. We work with the very best firms of forensic accountants, foreign lawyers and barristers and are innovative, rigorous and committed to achieving the best results for our clients at the earliest possible opportunity.

Within our civil fraud team, we also have a dedicated crypto and digital assets unit, which specialises in frauds involving crypto currencies, “non-fungible tokens” and exchanges.



Investigations:

Our team is led by Satnam Tumani, a member of the Legal 500 Hall of Fame for white collar crime and investigations matters. Satnam is supported by a diverse and truly multi-disciplinary team. The team includes former specialists from the Serious Fraud Office (SFO), Financial Conduct Authority (FCA), Crown Prosecution Service (CPS) and Medicines and Healthcare Products Regulatory Agency (MHRA). We have dedicated in-house investigators who are experts at gathering intelligence and evidence; conducting money-flow reviews; assisting with document reviews and supporting our legal teams with interviews and evidential assessments. Furthermore, we have in-house specialist criminal law Barristers, who undertake both advocacy and give advice on particularly complex areas of the criminal law. We are also one of the very few practices to have genuine and dedicated “crypto” and digital assets expertise. Our team specialises in cases involving crypto currencies, “Non-Fungible Tokens” and exchanges.

Our team has been significantly involved in most of the major SFO corporate investigations of the last two decades including: Rio Tinto, Airbus, Rolls Royce, Petrofac, Amec Foster Wheeler, Unaoil, GSK, Standard Bank, Innospec, Alstom, BAE Systems and Mabey & Johnson. We also have notable experience working on investigations conducted by the, FCA, CPS, HM Revenue & Customs (HMRC), the UK National Crime Agency (NCA), the Information Commissioner’s Office (ICO), the UK Financial Reporting Council (FRC), Department for Business, Innovation and Skills, the Department of Health, the Department for Work and Pensions and various Police forces.


Commercial Disputes

We handle a wide range of domestic and international dispute work. Our cases are invariably complex and sensitive in nature and frequently involve:

·Company shareholder and investor disputes

·Claims against directors for breach of fiduciary and contractual duties

·Partnership and joint venture disputes

·Disputes with banks and other financial institutions

·High value employment disputes involving the misuse of confidential information and breach of restrictive covenants

·Bankruptcy and insolvency disputes

·Professional negligence claims against lawyers, accountants, architects and other professional advisors

·International arbitrations before the LCIA and ICC


Many of our disputes are multi-jurisdictional in nature and involve applications for urgent interim relief, including worldwide “freezing injunctions” and applications and “Norwich Pharmacal” and “Bankers Trust” orders. We act both for and against individuals and companies. We even act for nation states. Because we only handle dispute-related work, we are genuinely “conflict-free”, meaning that we can bring litigation against the largest of companies, banks and other financial institutions without fear or favour.

We aim to provide an exceptional, partner-led, service with an emphasis on a rigour attention to detail, careful strategic thinking, and engineering the best possible outcomes for our clients at the earliest possible opportunity.
