Given the importance of very large online platforms or very large online search engines, in view of their reach and impact, their failure to comply with the specific obligations applicable to them may affect a substantial number of recipients of the services across different Member States and may cause large societal harms, while such failures may also be particularly complex to identify and address. For this reason the Commission, in cooperation with the Digital Services Coordinators and the Board, should develop the Union expertise and capabilities as regards the supervision of very large online platforms or very large online search engines. The Commission should therefore be able to coordinate and rely on the expertise and resources of such authorities, for example by analysing, on a permanent or temporary basis, specific trends or issues emerging with regard to one or more very large online platforms or very large online search engines. Member States should cooperate with the Commission in developing such capabilities, including through secondment of personnel where appropriate, and contributing to the creation of a common Union supervisory capacity. In order to develop the Union expertise and capabilities, the Commission may also draw on the expertise and capabilities of the Observatory on the Online Platform Economy as set up in Commission Decision of 26 April 2018 on setting up the group of experts for the Observatory on the Online Platform Economy, relevant expert bodies, as well as centres of excellence. The Commission may invite experts with specific expertise, including in particular vetted researchers, representatives of Union agencies and bodies, industry representatives, associations representing users or civil society, international organisations, experts from the private sector, as well as other stakeholders.
