Tony Pulis has lost a £3.7 million High Court fight with a former club.
Pulis, who manages West Bromwich Albion, had earlier this year been ordered to pay £3.7 million damages to former club Crystal Palace by a Premier League Managers' Arbitration Tribunal.
He had claimed that the decision was unfair and mounted a challenge in the High Court.
But judge Sir Michael Burton has ruled against him after a hearing in London.
Detail has emerged in a written ruling published by the judge on Monday.
