Funding a Credit Crunch: How Litigation Finance Has Fueled Global Actions Against Visa and Mastercard

Funding a Credit Crunch: How Litigation Finance Has Fueled Global Actions Against Visa and Mastercard

Mastercard and Visa are no strangers to legal action, having endured class actions and legal challenges all over the world. Currently, a collective action funded by Bench Walk Advisors accuses the credit giant of illegally overcharging Multilateral Interchange Fees (MIFs) in the UK. It has been asserted that MIFs, here charged as a percentage of each purchase, are unlawful. If the courts agree, merchants will be compensated for the money lost—possibly with interest. A similar case was recently settled in Canadian courts. Merchants across Canada will share a $131CA million settlement for businesses accepting Visa and Mastercard since 2001. Given these developments, we thought it prudent to take a look back at the Visa and Mastercard claims. What happened? How did we get here? How are litigation funders impacting the case? And what can we expect from all of this going forward? So, without further ado… The Story Behind the Case Visa and Mastercard have been accused of overcharging merchants on multilateral interchange fees, or MIFs. This fee is charged to the merchant’s bank in every credit card transaction. It also makes up the largest portion of the Merchant Service Charge—which is assessed simply so that the merchant may accept Mastercard and Visa payments from customers. Unlike other types of merchant fees, MIFs are not set with regard to market rates. In this case, the credit card companies are accused of unlawful and anti-competitive practices. Because merchants have no choice but to pay these fees, lest they forego the ability to accept credit card payments—Visa and Mastercard appear to be taking full advantage of the leverage they maintain over merchants. Merchants and banks pass these charges on to consumers, which means everyone is adversely impacted by this type of overcharging. The Upcoming UK Class Action The UK class action was launched in August of last year with funding from Bench Walk Advisors. Bench Walk is taking over for Therium Capital Management, the original funder slated to finance the exceptionally large claim, valued at GBP 15 billion. Interestingly, the Competition Appeals Tribunal (CAT) scrutinized the funding agreement, and observed that there was enough funding in the agreement to cover the potential costs of the claim, even with extensive disclosure motions. Bench Walk is said to be providing up to GBP 45.1 million in funding, with an additional GBP 15 million slated for adverse costs. The CAT has found estimated costs to be roughly GBP 32.5 million for the claim, leaving plenty in the budget should disclosure motions rain down, or the claimant class experience any additional unforeseen consequences. In August of 2021, a London court approved the class action. Claimants assert that as many as 46 million Britons may receive roughly GBP 300 each if the case is successful. As is de rigueur in funded cases, Mastercard is calling the class action “spurious” and asserting that it’s a glib and cynical ploy to make money. Ironic, no? According to financial ombudsman Walter Merricks, these consumer-focused class actions are designed to hold big businesses responsible for misdeeds. Noted class action focused firm Harcus Parker is helming the UK case, which includes merchants and customers who used credit cards between May 1992 and June 2008. In 2015, UK law capped MIFs at .3% on consumer credit transactions, and .2% for consumer debits. While the cap was not applicable to corporate or inter-regional transactions, Harcus Parker asserts that such MIFs should be zero. Bench Walk Advisors’ funding will help more than 100,000 companies pursue claims against Visa and Mastercard. The Case in Canada  Settlements with Capital One, Bank of America, National Bank, and others have been reached with merchants. Lawyers for the Canadian class action include Consumer Law Group, Branch MacMaster LLC, and Camp Fiorante Matthews Mogerman LLP. The settlement includes a provision giving merchants the ability to make surcharges (up to a cap) for the next five years minimum. This codicil seems less consumer-focused, as the end result will be customers paying surcharges with each credit card purchase. Consumers may find this especially galling, given recent inflation and a COVID-inspired increase in credit card shopping, both in-person and online. In Canada, Mastercard and Visa have settled with class action participants to the tune of $131 CAD. Merchants will be reimbursed for MIFs paid on credit transactions from 2001 forward. Smaller businesses (those which make under $5 million in yearly sales) may claim as much as $30 per year, up to a maximum reimbursement of $600. Both settlements have been approved by the courts. Meanwhile, none of the banks involved have not admitted any malfeasance. The Canadian class action did not rely on traditional litigation funding. Rather, lawyers were compensated from settlement funds as approved by the courts. Does this mean that third-party legal funding isn’t necessary for a successful class action in Canada? Not necessarily. The differences between funded class actions and cases taken on contingency can vary widely depending on the case at hand. In the United States In September of last year, Visa and Mastercard were both ordered to face antitrust class actions over MIFs by a Brooklyn judge. The class action includes claimant merchants who accepted Mastercard or Visa between 2004 and 2019. A settlement was reached in 2012, but was not approved by several large merchants. It was then overturned on appeal—resulting in a new settlement offer of a whopping $900 million more than the original settlement. A representative from Mastercard, which vociferously defended against the antitrust and unlawful fees allegations, stated that the company is pleased to have reached an agreement. That’s not surprising, given how frequently the company finds itself in court on the same type of accusation. Again, a Mastercard spokesperson asserted that the class actions were brought by “US-based lawyers and litigation funders primarily focused on making money…wasting the court’s time…” It’s noteworthy that in the US case, major retailers may see an even larger windfall. Walmart, Target, Kroger, and other large merchants have opted out of the settlement in the hopes of striking a better deal. A court has found that the credit card companies violated antitrust laws—ordering a preliminary settlement amount of between $5.5-6.25 billion. In short, US merchants may be reimbursed for interchange fees overpaid for the past 15 years. The preliminary settlement was approved by the courts. However, the Second Circuit Court of appeals has entertained objections to the settlement approval in March of this year. It’s unclear when a decision will be reached. Mastercard Around the World Mastercard in particular is no stranger to lawsuits, particularly those surrounding interchange fees. Jurisdictions around the world have pursued, or attempted to pursue, class action cases against the credit giant. These include:
  • European Union: 2012—resulting in Mastercard repealing earlier pricing changes and promising greater transparency in pricing.
  • France: 2009—resulting in Mastercard committing to reduce interchange fees across the board.
  • Poland: 2007—determined Mastercard’s interchange fees to be unlawful, while the Protection of Competition and Consumers disagreed. An appeal is pending
  • Hungary: 2009—Visa and Mastercard both found to have violated competition laws and fined $3 million.
  • Italy: 2010—Mastercard fined 2.7 euros, though this was annulled the following year.
  • United States: 2012—Mastercard opted out of a settlement of $7.25 billion, reducing the settlement amount to $5.7 billion. This is still a record-setting amount of an antitrust class action.
How are Litigation Funders Helping? As the appeals are being decided and the claims period draws near, a number of funders are offering post-settlement funding to claimants with payouts en route. This provides an avenue for struggling merchants to gain access to reimbursements without waiting. For small businesses hurt by rampant overcharging, this can be tremendously helpful. We can see from this that Litigation Finance can do more than ensure that class actions are funded and that claimants have their day in court. The industry can also monetize payouts, offering choices not previously available to members of a class. In short, it’s not just access to justice that the Litigation Finance industry provides, but access to much needed funds that can keep business afloat, especially during turbulent economic times. So What’s Next? All eyes will no doubt be watching for the outcome of the UK anti-competition case against Visa and Mastercard. The European Commission has already declared that Mastercard breached its duty when setting its fees, thus the meritorious nature of the claim should never have been in question. It is now up to a court to decide the culpability of the credit card giants, as per UK law. One interesting final note: you might have been wondering how a financial ombudsman such as Walter Merricks can possibly discern the specific payout that each of the 46 million or so claimants deserve? Well, the answer is he likely can’t, but that won’t affect the outcome of the case. The Supreme Court has found that the impossibility of Merricks’ task does not take defendants off the hook. Instead, Merricks may seek an aggregate award with data that affirms an appropriate amount of damage, even if he cannot apply a methodology that is fair to everyone in terms of a final payout. As opponents of the action have duly noted, the court’s ruling could potentially “open the floodgates” to a bevy of future class actions, similar in scope to what we’re witnessing here. Perhaps ironically, many in the funding community are nodding their heads, as the potential for large, US-style class actions in the UK is viewed as a positive development – greater access to justice, after all. We will continue to bring you updates on the Merricks claim as it winds its way through the UK legal system.

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.
