The 1985–86 Yugoslav First League season was marked by scandal and controversy due to allegedly wide match-fixing during the last week of fixtures.
After the last week was played, FK Partizan was crowned champion due to better goal difference than second-placed Red Star Belgrade.
As a result their week 34 fixture was registered as a 3–0 defeat, and the club was thus stripped of the league title, which was now awarded to Red Star.
What followed on domestic front was a series of appeals and lawsuits and the entire case eventually went all the way to the Yugoslav Constitutional Court.
By the time Yugoslav Constitutional Court delivered its final ruling to the Court of Joint Labour of SR Serbia on 29 July 1987, the next league season was already completed with FK Vardar winning the title due to 12 teams starting the season with -6 points.
