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 the disqualification from the competition.
The UEFA Control, Ethics and Disciplinary Body can validate the result as it stood at the moment when the match was abandoned if the match result was to the detriment of the club responsible for the match being abandoned.
If a club is disqualified or for any reason withdraws from the competition before completion of its matches in the group stage, the results of all of its matches are declared null and void, and its points forfeited.
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.
