If any party to the match has any reason to doubt whether a particular match of the competition can take place as scheduled (including but not limited to pitch, facility and infrastructure, safety and security, operational and/or organisational problems and/or weather conditions), they must notify the UEFA administration immediately. If the UEFA administration receives any such notification, or has any reason itself to believe that a match may not be able to be played as scheduled, it decides if any change will be made to the stadium, venue, date and/or kick-off time. Such a decision by the UEFA administration is final. If the venue or stadium is changed, the costs of staging the match(es) concerned are borne by the host association.
The referee decides if a match which has started must be suspended. This decision is made after consultation with the UEFA match delegate and, when possible, the UEFA administration.
