Matrix Chambers offers ‘a large talent pool at several different levels of seniority’ and multi-disciplinary approach to enforcement proceedings. The set enjoys a strong reputation internationally, thanks in part to its strong work relationships with firms in the US and Hong Kong, as well as its extensive experience of engaging with foreign authorities the likes of the US DoJ; in addition, Tim Owen QC is also noted for his focus on offshore jurisdictions, including a judicial appointment to the Grand Court of the Cayman Islands. Another strength of the team lies in its representation of a mix of global companies, banks and financial institutions in fraud, bribery, corruption and money laundering investigations conducted by UK agencies, including the SFO and the FCA; Clare Montgomery QC and Alex Bailin QC remain among the country’s most highly regarded specialists in this space. In October 2020, the set expanded its market visibility in the financial regulatory space with multiple lateral hires, including those of Nichola Higgins of Doughty Street Chambers and former First Senior Treasury Counsel Richard Whittam QC of 2 Bedford Row.

In another matter, Ní Ghrálaigh acted for four anti-arms trade campaigners in an appeal in DPP v Ziegler before the Supreme Court, in which the Supreme Court reinstated the defendants’ initial acquittal of the charge of wilful obstruction of a highway after they attempted to disrupt deliveries to the DSEI defence industry trade show in London in 2017.
