Nottingham Forest owner Evangelos Marinakis has lost his appeal against a five-game stadium ban.
The 57-year-old was found guilty of improper conduct for spitting on the floor as the match officials walked past following Forest's 1-0 Premier League defeat by Fulham at the City Ground on 28 September.
In publishing its written reasons behind the decision, the commission said there was "no excuse" for such an "an egregious display of disrespectful behaviour" that could "fuel disrespect towards match officials".
Marinakis, who has already served three games of the ban, denied the charge.
