Turkish club Fenerbahce have been fined 4 million lira ($123,000) and Galatasaray awarded a 3-0 win after the club's protests at the Turkish Super Cup on April 7.
Fenerbahce fielded their under-19 team and walked off the field in the third minute, in a pre-planned protest.
The club had asked for the game to be postponed before the Europa League quarter-final tie with Olympiakos, but the request was denied.
Fenerbahce were also unhappy with the appointment of a Turkish referee.
The Istanbul club had requested a foreign referee take charge of the match, but the Turkish federation dismissed their request.
Galatasaray took the lead after one minute in Sanliurfa with a Mauro Icardi goal, and Fenerbahce departed the field before the restart.
Fenerbahce have accused the Turkish Football Federation of unfair treatment after two of their players were given one-match bans for fighting with Trabzonspor supporters, who stormed the pitch during a league game on 17 March.
The club also considered leaving the Turkish Super Lig but members voted against doing so.
