A Delaware investment vehicle closely affiliated with Burford Capital is pursuing a debt claim of roughly $109 million against Alberta lawyer Jeffrey Rath and his firm, Rath & Company, alleging default on a litigation funding agreement first entered into in 2018.
As reported by Global News, Diriba Investments LLC claims the firm defaulted two years ago on financing tied to First Nations and COVID-19 litigation, with the outstanding balance now standing at approximately $108.8 million plus interest and costs. Diriba acts as agent for co-funder Western Springs Investments LP, also a Delaware entity. A 2023 amendment expanded the agreement's scope to cover all claimant-side work at the firm, including First Nations treaty claims and litigation over COVID-19 restrictions.
The alleged breaches include failure to provide monthly reports, failure to keep the funders informed, failure to report or remit proceeds, non-disclosure of client terminations, and the granting of competing security to a separate Delaware entity, Vance SPV LLC. Diriba issued a default notice in November 2024 and, in late July 2026, served a formal demand alongside a notice of intention to enforce security under the Bankruptcy and Insolvency Act describing the firm as an "insolvent person."
The supporting affidavit was sworn by Paul Mysliwiec, Burford Capital's deputy general counsel, acting as Diriba's authorized representative. Burford did not respond to requests for comment, and Diriba's Calgary counsel declined to comment.
The claim runs alongside separate actions by the Tallcree and Sturgeon Lake First Nations alleging misappropriation of trust funds, a Mareva injunction freezing $8.5 million, and a court-appointed receiver. Diriba is seeking an expanded receivership mandate at a September 14 hearing in Calgary. The allegations have not been proven in court, and Rath denies wrongdoing.
