L 109/14 Official Journal of the European Union 12.4.2014 COMMISSION REGULATION (EU) No 372/2014 of 9 April 2014 amending Regulation (EC) No 794/2004 as regards the calculation of certain time limits, the hand- ling of complaints, and the identification and protection of confidential information (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Council Regulation (EC) No 659/1999 of 22 March 1999 laying down detailed rules for the application of Article 108 of the Treaty on the Functioning of the European Union ('), and in particular Article 27 thereof, After consulting the Advisory Committee on State aid, Whereas: (1)  In the context of the modernisation of State aid rules to contribute both to the implementation of the Europe 2020 strategy for growth and to budgetary consolidation (3, Regulation (EC) No 659/1999 was amended by Regulation (EU) No 734/2013 (*) to improve the effectiveness of State aid control. That amendment sought in particular to render more effective the handling of complaints by the Commission and to introduce powers for the Commission to request information directly from market participants and to conduct investigations into sectors of the economy and into aid instruments. (2)  In light of those amendments, it is necessary to identify the events determining the starting point for the calcula- tion of time-limits in the context of requests for information addressed to third parties pursuant to Regulation (EC) No 659/1999. (3) The Commission may, on its own initiative, examine information on unlawful aid from any source, in order to assess compliance with Articles 107 and 108 of the Treaty. In that context, complaints are an essential source of information for detecting violations of State aid rules. It is therefore important to define clear and efficient pro- cedures for handling complaints lodged with the Commission. (4)  According to Article 20 of Regulation (EC) No 659/1999, only interested parties may submit complaints to inform the Commission of any alleged unlawful aid or misuse of aid. To that end, natural and legal persons submitting complaints should be required to demonstrate that they are interested parties within the meaning of Article 1(h) of Regulation (EC) No 659/1999. (5)  To streamline the handling of complaints and at the same time increase transparency and legal certainty, it is appropriate to define the information that complainants should provide to the Commission. In order to ensure that the Commission receives all relevant information regarding alleged unlawful or misused aid, Regulation (EC) No 659/1999 requires interested parties to complete a form and submit all the mandatory information requested therein. The form to be used for that purpose should therefore be established. () OJL83,27.3.1999, p. 1.
