Band 3
Provided by Jonathan McDonagh
Jonathan’s background as a commercial chancery junior provides a valuable, and rare, specialism in group litigation disputes involving complex issues of jurisdiction, private international law, corporate liability, and fraud.
In recent years, Jonathan has been instructed in several major pieces of ongoing group litigation including MunÃcipio de Mariana and oths v BHP Group (the Fundão Dam disaster litigation), the largest opt-in group action ever brought before the English courts. With an estimated 600,000+ claimants, the case has generated global media coverage as it seeks to establish parent-company liability for an environmental catastrophe in Brazil; and along the way it has provided new precedents for issues of jurisdiction and how to conduct large-scale multi-national class actions before the English courts. Jonathan has acted for the claimants from the outset of this litigation.
He has also been instructed across a range of the ‘dieselgate’ claims, including the Crossley v VW litigation; and more recently in respect of claims against several other manufacturers that will be progressing through the English courts in 2024.
In addition, Jonathan frequently advises funders and insurers in respect of group claims.

He is an extremely effective advocate both in writing and orally, and has superb judgement, particularly when it comes to tactical decisions. There is little he doesn't know about group litigation.
Jon is a silk in all but name. He is very commercial, produces extremely impressive written work, and is great on his feet. He would be an asset to any team litigating a complex and high stakes case.
