Upon request from one or more competent authorities, the European Parliament, the Council, the Commission, the relevant Stakeholder Group, or on its own initiative, including when this is based on well substantiated information from natural or legal persons, and after having informed the competent authority concerned, the Authority shall outline how it intends to proceed with the case and, where appropriate, investigate the alleged breach or non-application of Union law.

▼M1

Without prejudice to the powers laid down in Article 35, the competent authority shall, without delay, provide the Authority with all information which the Authority considers necessary for its investigation, including with regard to how the acts referred to in Article 1(2) are applied in accordance with Union law.

▼M2

Without prejudice to the powers laid down in Article 35, the Authority may, after having informed the competent authority concerned, address a duly justified and reasoned request for information directly to other competent authorities whenever requesting information from the competent authority concerned has proven, or is deemed to be, insufficient to obtain the information that is deemed necessary for the purpose of investigating an alleged breach or non-application of Union law.

The addressee of such a request shall provide the Authority with clear, accurate and complete information without undue delay.
