4. By way of derogation from paragraph 3, in situations of serious, repeated or systematic breaches by obliged entities operating through establishments or other types of infrastructure in their territory as referred to in paragraph 1 that require immediate remedies, supervisors of the host Member State shall be allowed at their own initiative to take appropriate and proportionate measures to address those breaches. Those measures shall be temporary and be terminated when the breaches identified are addressed, including with the assistance of or in cooperation with the supervisors of the home Member State of the obliged entity.
Member States shall ensure that the supervisors of the host Member State inform the supervisor of the home Member State of the obliged entity immediately upon identification of the serious, repeated or systematic breaches and upon taking any measure pursuant to the first subparagraph, unless measures are taken in cooperation with the supervisors of the home Member State.
