In a significant legal victory for Calvin Harris, a retired federal judge has ordered the artist’s former business manager, Thomas St. John, to pay more than $13.4 million. The judgment marks the conclusion of the first phase of a contentious arbitration process sparked by allegations of financial mismanagement.
Harris, whose real name is Adam Wiles, initiated the proceedings following claims that St. John abused their professional relationship to fund a failed real estate venture in Hollywood. While the broader dispute continues, this initial ruling focuses on a specific loan that St. John failed to repay.
Judge Michael R. Wilner ruled that St. John and his associated entities are jointly and severally liable for the outstanding debt. The total sum of $13,438,666.55 awarded to Harris’ team includes the $10,000,000 loan principal along with $2,666,666.56 in interest. The final figure also accounts for a $371,999.99 late charge, a $200,000 origination fee, and a $200,000 exit fee.
The judge noted that there was no dispute regarding St. John’s failure to pay back the principal sum by the required date.
Despite this multi-million dollar win, the legal conflict is far from over. This judgment only addresses the $10 million loan portion of the dispute. The arbitrator has yet to decide on the status of an additional $12 million equity investment Harris made into the same project, or the larger question of whether St. John engaged in fraudulent activity to secure these funds.
Harris has characterized the investment as a “boondoggle,” alleging his money was funnelled into a project that never broke ground. St. John continues to deny all allegations of fraud, maintaining that Harris was a willing participant in the investment and describing the claims as “categorically false.”
As the arbitration moves into its next phase, St. John faces mounting pressure from other directions. His management firm is currently in bankruptcy, and he is defending a separate lawsuit from fellow artist Eric Prydz, who alleges the manager took $269,000 in unauthorised commissions. St. John has dismissed those allegations, labelling them “wholly fabricated.”
For Harris, this judgment secures the return of his initial loan plus significant interest, though the fate of his remaining $12 million remains in the hands of the arbitrator.
