The Tour has already issued fines of 100,000 pounds (A$186,000) to 17 players who played in the first two LIV Golf events outside London and Portland, Oregon.

Now it is going after 26 players with fines that range from 12,500 pounds to 100,000 pounds for each tournament they played without a release. The amount depends on what the Tour deems harmed the DP World Tour.

Players also could face suspensions– up to eight regular DP World Tour events on the schedule – if they pay their fines and remain members. Any suspension would start at the Porsche European Open in Germany on June 1-4.

Sergio Garcia was the only player who did not pay the initial fine. Garcia, Lee Westwood, Ian Poulter and Richard Bland resigned their memberships last week. More players are likely to resign from the DP World Tour.

Two tournaments into LIV's inaugural season, a group of DP World Tour players sought court relief from tour sanctions and were allowed to play pending an outcome in binding arbitration.

Sport Resolutions ruled in favour of the tour that it had a "legitimate and justifiable interest" in enforcing its regulation with sanctions.

The Saudi-backed LIV Golf has pumped $US300 million ($A448 million) into the Asian Tour, which staged a tournament outside London last year and has two more tournaments scheduled this year for England and Scotland.

The Tour said in a statement that the sanctions were determined on a case-by-case basis to recognise differences among tournaments and their impact on the Tour's broadcast partners and sponsors.

Any suspension would run consecutively, though it would not include major champions. The tour said players who resigned would only be eligible for reinstatement if they paid their fines, from which point their suspensions would start.

Since the Sport Resolutions decision, LIV Golf has played in Australia, Singapore and this week in Oklahoma. The DP World Tour said it would decide on later sanctions involving those tournaments.
