Article 4
Where Union law differs from the international standards referred to in Article 3 of this decision and notification to the ICAO of those differences is therefore required in accordance with Article 38 of the Chicago Convention, the Commission shall, in due time and at least two months before any deadline set by the ICAO for the notification of differences, submit to the Council, for discussion and approval, a document, based in particular on the information provided by the EASA in accordance with Article 90(4) of Regulation (EU) 2018/1139, where applicable, setting out details of the differences to be notified to the ICAO, and where appropriate, indicating what flexibility is available to Member States as regards the form of the notification. The position to be taken pursuant to this Article shall be expressed by all Member States acting jointly in the interests of the Union.
