Parties in Burford-Funded Argentina Claim Remain Far Apart on Payout Amount

Parties in Burford-Funded Argentina Claim Remain Far Apart on Payout Amount 

Cases with a prolonged duration and timelines that span nearly a decade are not uncommon for those in the business of litigation finance. However, even in cases where claimants receive a favourable judgement, there is always the issue of determining the size of the award, which further prolongs these lawsuits. A recent article by Bloomberg Law provides an update on the three-day trial in the case of Petersen Energia Inversora, S.A.U. v. Argentine Republic, which ended with the opposing parties still $6.5 billion apart on what they think the proposed payout should be. The case, which dates back to 2015, was brought on behalf of YPF SA shareholders, who argued that the Argentine government failed to offer a required payout after it re-nationalized the oil company in 2012.  As LFJ previously reported, Judge Loretta A. Preska ruled that Argentina was liable for the shareholders’ losses in a summary judgement in March of this year. During last month’s trial in the Southern District of New York, the shareholders argued that the payout could amount to as much as $16 billion, whilst Argentina provided a much lower estimate of $9.5 billion. The significant distance between the two amounts revolved around a number of key issues, including the date that the government took back control of YPF, with the two parties specifying dates that are three weeks apart.  The outcome of the trial has particular significance for Burford Capital who invested $16.6 million in the litigation, and following the March judgement, had stated that the final award could total in excess of $7.5 billion. This figure is notably lower than Argentina’s proposed payout. However, Judge Preska provided no estimate of when she might deliver a ruling on the payout and attorneys for the Argentine government have already made clear that they will appeal the award, regardless of the Judge’s ruling.

Siltstone Capital Reaches Settlement with Former General Counsel

By John Freund |

Litigation funder Siltstone Capital and its former general counsel, Manmeet “Mani” Walia, have reached a settlement resolving a trade secrets lawsuit that had been pending in Texas state court. The agreement brings an end to a dispute that arose after Walia’s departure from the firm, following allegations that he misused confidential information to establish a competing business in the litigation finance space.

As reported in Law 360, Siltstone filed suit in late 2025, claiming that Walia, who had served as general counsel and was closely involved in the company’s internal operations, improperly accessed and retained proprietary materials after leaving the firm. According to the funder, the information at issue included sensitive business strategies and other confidential data central to Siltstone’s competitive position. The lawsuit asserted claims under Texas trade secrets law, along with allegations of breach of contract and breach of fiduciary duty tied to confidentiality and restrictive covenant provisions.

Walia disputed the allegations as the case moved forward, setting the stage for what appeared to be a hard-fought legal battle between the former employer and its onetime senior executive. However, before the dispute could be fully litigated, the parties opted to reach a negotiated resolution. Following the settlement, Siltstone moved to dismiss the case with prejudice, signaling that the matter has been conclusively resolved and cannot be refiled.

The specific terms of the settlement have not been made public, which is typical in cases involving alleged trade secret misappropriation. While details remain confidential, such resolutions often include mutual releases of claims and provisions aimed at protecting sensitive information going forward.

High Court Refuses BHP Permission to Appeal Landmark Mariana Liability Judgment 

By John Freund |

Pogust Goodhead welcomes the decision of Mrs Justice O’Farrell DBE refusing BHP’s application for permission to appeal the High Court’s judgment on liability in the Mariana disaster litigation. The ruling marks a major step forward in the pursuit of justice for over 620,000 Brazilian claimants affected by the worst environmental disaster in the country’s history. 

The refusal leaves the High Court’s findings undisturbed at first instance: that BHP is liable under Brazilian law for its role in the catastrophic collapse of the Fundão dam in 2015. In a landmark ruling handed down last November, the Court found the collapse was caused by BHP’s negligence, imprudence and/or lack of skill, confirmed that all claimants are in time and stated that municipalities can pursue their claims in England. 

In today’s ruling, following the consequentials hearing held last December, the court concluded that BHP’s proposed grounds of appeal have “no real prospect of success”. 

In her judgment, Mrs Justice O’Farrell stated:  “In summary, despite the clear and careful submissions of Ms Fatima KC, leading counsel for the defendants, the appeal has no real prospect of success. There is no other compelling reason for the appeal to be heard. Although the Judgment may be of interest to other parties in other jurisdictions, it is a decision on issues of Brazilian law established as fact in this jurisdiction, together with factual and expert evidence. For the above reasons, permission to appeal is refused”. 

At the December hearing, the claimants - represented by Pogust Goodhead - argued that BHP’s application was an attempt to overturn detailed findings of fact reached after an extensive five-month trial, by recasting its disagreement with the outcome as alleged procedural flaws. The claimants submitted that appellate courts do not re-try factual findings and that BHP’s approach was, in substance, an attempt to secure a retrial. 

Today’s judgment confirmed that the liability judgment involved findings of Brazilian law as fact, based on extensive expert and factual evidence, and rejected the defendants’ arguments, who now have 28 days to apply to the Court of Appeal.  

Jonathan Wheeler, Partner at Pogust Goodhead and lead of the Mariana litigation, said:  “This is a major step forward. Today’s decision reinforces the strength and robustness of the High Court’s findings and brings hundreds of thousands of claimants a step closer to redress for the immense harm they have suffered.” 

“BHP’s application for permission to appeal shows it continues to treat this as a case to be managed, not a humanitarian and environmental disaster that demands a just outcome. Every further procedural manoeuvre brings more delay, more cost and more harm for people who have already waited more than a decade for proper compensation.” 

Mônica dos Santos, a resident of Bento Rodrigues (a district in Mariana) whose house was buried by the avalanche of tailings, commented:  "This is an important victory. Ten years have passed since the crime, and more than 80 residents of Bento Rodrigues have died without receiving their new homes. Hundreds of us have not received fair compensation for what we have been through. It is unacceptable that, after so much suffering and so many lives interrupted, the company is still trying to delay the process to escape its responsibility." 

Legal costs 

The Court confirmed that the claimants were the successful party and ordered the defendants to pay 90% of the claimants’ Stage 1 Trial costs, subject to detailed assessment, and to make a £43 million payment on account. The Court also made clear that the order relates to Stage 1 Trial costs only; broader case costs will depend on the ultimate outcome of the proceedings. 

The costs award reflects the scale and complexity of the Mariana case and the way PG has conducted this litigation for more than seven years on a no-win, no-fee basis - funding an unprecedented claimant cohort and extensive client-facing infrastructure in Brazil without charging clients. This recovery is separate from any damages award and does not reduce, replace or affect the compensation clients may ultimately receive.

Homebuyers Prepare Competition Claims Against Major UK Housebuilders

By John Freund |

A group of UK homebuyers is preparing to bring competition law claims against some of the country’s largest housebuilders, alleging anti competitive conduct that inflated new home prices. The prospective litigation represents another significant test of collective redress mechanisms in the UK and is expected to rely heavily on third party funding to move forward.

An announcement from Hausfeld outlines plans for claims alleging that leading residential developers exchanged commercially sensitive information and coordinated conduct in a way that restricted competition in the housing market. The proposed claims follow an investigation by the UK competition regulator, which raised concerns about how housebuilders may have shared data on pricing, sales rates, and incentives through industry platforms. According to the claimant lawyers, this conduct may have reduced competitive pressure and led to higher prices for consumers.

The claims are being framed as follow on damages actions, allowing homebuyers to rely on regulatory findings as a foundation for civil recovery. The litigation is expected to target multiple large developers and could involve tens of thousands of affected purchasers, given the scale of the UK new build market during the relevant period. While damages per claimant may be relatively modest, the aggregate exposure could be substantial.

From a procedural perspective, the case highlights the continued evolution of collective competition claims in the UK. Bringing complex, multi defendant actions on behalf of large consumer groups requires significant upfront investment, both financially and operationally. Litigation funding is therefore likely to be central, covering legal fees, expert economic analysis, and the administration required to manage large claimant cohorts.
