A panel has ruled that LIV Golf rebels committed “serious breaches” by leaving the DP World Tour to compete in Saudi Arabia-sponsored events.
The 12 players have now been told to pay the original £100,000 fines within 30 days.
Sporting Resolutions, an arbitration body, stated that DP World Tour CEO Keith Pelley “acted entirely reasonably in refusing releases.”
Pelley praised the decision of the three-person independent panel.
LIV players may now face bans from the DP World Tour and the Ryder Cup in Europe.
England’s Ian Poulter and Lee Westwood were among 12 players who filed an appeal against the tour’s proposed sanctions for competing in the inaugural LIV event at the Centurion Club in Hertfordshire in June.
They were barred from the Scottish Open and two US events, as well as fined, for failing to comply with the tour’s refusal of waivers to compete in the LIV tournament, which coincided with the DP World Tour’s Scandinavian Mixed event.
The players contended that they were independent contractors who had previously been permitted to compete on rival circuits such as the PGA Tour.
The DP World Tour objected, claiming that players competing in concurrent events on the LIV tour were harming the DP World Tour’s long-established calendar.
During the closed-door hearing in February, the panel determined that the DP World Tour “has a legitimate and justifiable interest in protecting the rights of its membership.”
“We are delighted that the panel recognized that we have a responsibility to our full membership to do this and that the process we followed was fair and proportionate,” Pelley said in a statement.
“We were simply administering the regulations that our members created and signed up to when we decided the level of these sanctions last June.”
