Judgment_paragraph 30 · Carrefour Hypermarchés SAS and Others v Ministre des Finances et des Comptes publics (C-510/16)

30As regards the context in which the concept is used and the objective pursued by Article 4(1) of Regulation No 794/2004, it must be stated that that provision implements the system of prior control established by Article 108(3) TFEU over proposals for alterations to existing aid, under which the Commission is required to examine the compatibility of the planned aid with the internal market (see, to that effect, judgment of 12 February 2008, CELF and Ministre de la Culture et de la Communication, C‑199/06, EU:C:2008:79,, paragraphs 37 and 38). The aim of that system of prior control is that only aid that is compatible with the internal market should be implemented (see, to that effect, judgments of 21 November 2013, Deutsche Lufthansa, C‑284/12, EU:C:2013:755, paragraphs 25 and 26, and of 19 July 2016, Kotnik and Others, C‑526/14, EU:C:2016:570, paragraph 36).
