If a club refuses to play or is responsible for a match (including any penalty shoot-out) not taking place or not being played in full, the UEFA Control, Ethics and Disciplinary Body declares the match forfeited by the club concerned. Moreover, if the circumstances of the case so justify, the UEFA Control, Ethics and Disciplinary Body may impose any further disciplinary measures deemed appropriate on the club concerned, including disqualification from the competition.
The UEFA Control, Ethics and Disciplinary Body can validate the result as it stood (i.e. abandon the match) at the moment when the match was suspended if the match result was to the detriment of the club responsible for the match being suspended.
If a club is disqualified or for any reason withdraws from the competition before all its matches in the league phase have been played, the results of all its matches played until that moment remain valid. A calculation of points will need to take place upon completion of the league phase to take the cancelled matches into account. Any club that has not been able to play its scheduled match against a disqualified/withdrawn club is awarded the average number of points earned by all clubs in its same seeding pot against the clubs in the same pot as that disqualified/withdrawn club in home matches, if the affected club was due to play at home, or in away matches if the affected club was due to play away. The league phase points of all matches that have been played, including the points obtained by clubs in matches involving the disqualified/withdrawn club before their disqualification/withdrawal are not adjusted in any way, and all taken into account for the average points calculation.
A club that refuses to play or is responsible for a match not taking place or not being played in full may lose all rights to payments from UEFA, depending on the gravity of the circumstances.
Upon receipt of a reasoned and well-documented request from the aggrieved club(s), the UEFA administration may set an amount of compensation due for financial loss.
