The punishment relates to unpaid debts
UEFA have banned Serbian club Partizan Belgrade from European club competitions for three seasons over unpaid debts.
In UEFA's documentation of the case, they state that Partizan have unpaid debts of about €2.5 million in September 2016.
European football's governing body also ruled that they also broke rules on unpaid debts on three occasions over the past five years, stating that they breached "Articles 65(1), 66(1) and 66bis(1) of the CL&FFP Regulations".
The punishment of three years out of European club competition means they will be barred from participating in the Champions League and European League until after the conclusion of the 2019-2020 season.
"In light of the foregoing, the CFCB Adjudicatory Chamber considers that an exclusion from the next UEFA club competition for which the Club would otherwise qualify in the next three (3) seasons (i.e. the 2017/18, 2018/19 and 2019/2020 seasons) is required in order to serve as an adequate deterrent," said UEFA.
"In addition, costs of three thousand Euros (€3,000) are required to be paid by Partizan, in accordance with Article 32(2) of the Procedural Rules."
Since the break up of Yugoslavia, Serbia have won their national league seven times, with the most recent triumph coming in 2015.
They have also won the Serbian Cup four times in the last 10 years.
The club regularly qualify for European competition. In the 2010-11 season, they took on Irish record champions Shamrock Rovers in a playoff for a place in the Europa League group stages with the Dublin side prevailing and making history with a 3-2 aggregate win.
