Judgment_paragraph 37 · Criminal proceedings against Mathieu Blaise and Others (C-616/17)

37In those circumstances, given that, first, in the procedure under Article 267 TFEU, the interpretation of national law is exclusively for the referring court (see, to that effect, judgment of 13 November 2018, Čepelnik, C‑33/17, EU:C:2018:896, paragraph 24 and the case-law cited), and, second, Regulation No 1107/2009 establishes the rules whereby the harmfulness to human health or to animal health or to the environment of such products and the active substances of which those products are composed must be assessed before they can be authorised by a Member State, it cannot be held that questions seeking an examination of the compliance of that regulation with the precautionary principle manifestly bear no relation to the actual facts of the main action or its purpose.
