Pogust Goodhead law firm has appointed Jonathan Edward Wheeler as a partner and Head of Mariana Litigation, adding heavyweight firepower to the team driving one of the largest group claims in English legal history following the firm’s landmark liability win against BHP in the English courts.

Jonathan joins Pogust Goodhead from Morrison Foerster in London, where he was a leading commercial litigation partner, having served for seven years as office co-managing partner and for 15 years as Head of Litigation. A specialist in complex, cross-border disputes, Jonathan has extensive experience acting in high-value commercial litigation, civil fraud and asset tracing, international trust disputes, contentious insolvency and investigations across multiple jurisdictions.

In his new role, Jonathan will assume strategic leadership of the proceedings arising from the Mariana dam disaster against mining giant BHP, overseeing the continued development of the case into the damages phase and working closely with colleagues in Brazil, the UK, the Netherlands and beyond.

Howard Morris, Chairman at Pogust Goodhead said: “Jonathan is a heavyweight addition to Pogust Goodhead and to our Mariana team. His track record in running some of the most complex cross-border disputes in the English courts, together with his leadership experience, make him exactly the kind of senior figure we need after our historic liability victory. Our clients will benefit enormously from his expertise and judgment.”

Jonathan Wheeler said: “It is a privilege to join Pogust Goodhead at such a pivotal moment in the Mariana case. The recent liability judgment is a watershed for access to justice and corporate accountability. I am honoured to help lead the next phase of this extraordinary litigation and to work alongside a team that has shown such determination in seeking justice for hundreds of thousands of victims.”

Alicia Alinia, CEO at Pogust Goodhead said: “Bringing in lawyers of Jonathan’s calibre is a strategic choice. As we expand the depth and breadth of our disputes practice globally, we are investing in senior talent who can help us deliver justice at scale for our clients and build an even more resilient firm.”

The Mariana proceedings in England involve over 600,000 of Brazilian individuals, businesses, municipalities, religious institutions and Indigenous communities affected by the 2015 Fundão dam collapse in Minas Gerais, Brazil. Following the English court’s decision on liability on the 14th of November 2025, the case will now move into the next stage focused on damages and the quantification of losses on an unprecedented scale.
