Gus Poyet has lost his appeal against his sacking by Brighton, the club have confirmed.
Poyet was axed for gross misconduct last month having previously been suspended by the club in the aftermath of the play-off defeat by Crystal Palace.
Brighton have since appointed Oscar Garcia as head coach and they have revealed that, after a two-day appeal hearing, Poyet's dismissal has been upheld.
A statement on the club's website read: "Following a suspension, investigation, disciplinary meeting, and separate appeal hearing, which was conducted by three members of the club's board in London on July 11 and July 12 2013, Brighton & Hove Albion today confirmed that after further consideration Gus Poyet's dismissal for gross misconduct has been upheld.
"The panel's decision was delivered to Gus Poyet and his advisers a short time ago.
"The club's internal disciplinary process is now complete. In line with the club's policy to ensure and maintain confidentiality and dignity throughout this process, no further details of the disciplinary or appeal hearings will be released at this time.
"Despite the extremely disappointing end to Mr Poyet's career with Brighton & Hove Albion, the club would like to acknowledge Mr Poyet's service to the club, which included leading the club to the Football League League One championship in 2011 and to its highest league finish for more than 30 years in 2013."
