(23)For the purposes of the procedure for breach of Union law provided for in Article 17 of the founding regulations and in the interest of proper application of Union law, it is appropriate to ease, and speed up, the ESAs’ access to information. They should therefore be enabled to request information directly, via a duly justified and reasoned request, from 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.
