2 If one or more of a member association or club’s supporters engage in the behaviour described in paragraph 1, the member association or club responsible is punished with a minimum of a partial stadium closure.
3 The following disciplinary measures apply in the event of recidivism: a. a second offence is punished with one match played behind closed doors and a fine of € 50,000; b. any subsequent offence is punished with more than one match behind closed doors, a stadium closure, the forfeiting of a match, the deduction of points and/or disqualification from the competition.
4 If the circumstances of the case require it, the competent disciplinary body may impose additional disciplinary measures on the member association or club responsible, such as the playing of one or more matches behind closed doors, a stadium closure, the forfeiting of a match, the deduction of points and/or disqualification from the competition.
5 If the match is suspended by the referee because of racist and/or discriminatory conduct, the match may be declared forfeit. 6 The above disciplinary measures may be combined with specific directives aimed at tackling such conduct.
