Recital 140

In view of both the particular challenges that may arise in seeking to ensure compliance by providers of very large online platforms or of very large online search engines and the importance of doing so effectively, considering their size and impact and the harms that they may cause, the Commission should have strong investigative and enforcement powers to allow it to investigate, enforce and monitor compliance with the rules laid down in this Regulation, in full respect of the fundamental right to be heard and to have access to the file in the context of enforcement proceedings, the principle of proportionality and the rights and interests of the affected parties.
