On May 15, 2013 the Polish FA announced that Polonia Warsaw won't receive the Ekstraklasa license for 2013–14 season, citing financial issues. The club's appeal was rejected on May 28. As a result, Polonia was relegated to 2013–14 I Liga instead of the 15th placed Ekstraklasa team.
The Polish FA also deemed GKS, Widzew, Pogoń, Polonia and Ruch as well as Podbeskidzie and Jagiellonia ineligible to compete in UEFA competitions. Śląsk and Wisła, although initially denied the licence due to submitting incomplete financial forecasts, were able to fulfil the requirements during the appeal procedure and received the UEFA licence. Also, the FA's decision to exclude Górnik from the European competitions was cancelled, as the club, whose home stadium is undergoing renovative work, has made arrangements to use another venue as their home field in the event of their qualification to the 2013–14 Europa League. The three clubs were instead fined 100,000 zł, and 20,000 zł.
