In those circumstances, the Court of Session (Scotland) decided to stay the proceedings and to refer the following questions to the Court for a preliminary ruling: ‘(1) On a proper interpretation of EU law respecting the common organisation of the market in wine, in particular Regulation (EU) No 1308/2013, is it lawful for a Member State to promulgate a national measure which prescribes a minimum retail selling price for wine related to the quantity of alcohol in the sale product and which thus departs from the basis of free formation of price by market forces which otherwise underlies the market in wine? (2) In the context of a justification sought under Article 36 TFEU, where: (i) a Member State has concluded that it is expedient in the interest of the protection of human health to increase the cost of consumption of a commodity — in this case alcoholic drinks — to consumers, or a section of those consumers; and (ii) that commodity is one in respect of which the Member State is free to levy excise duties or other taxes (including taxes or duties based upon alcoholic content or volume or value or a mixture of such fiscal measures), is it permissible under EU law, and if so under what conditions, for a Member State to reject such fiscal methods of increasing the price to the consumer in favour of legislative measures fixing minimum retail prices which distort intra-EU trade and competition? (3) Where a court in a Member State is called upon to decide whether a legislative measure which constitutes a quantitative restriction on trade incompatible with Article 34 TFEU may yet be justified under Article 36 TFEU, on the grounds of the protection of human health, is that national court confined to examining only the information, evidence or other materials available to and considered by the legislator at the time at which the legislation was promulgated? And if not, what other restrictions might apply to the national court’s ability to consider all materials or evidence available and offered by the parties at the time of the decision of the national court? (4) Where a court in a Member State is required, in its interpretation and application of EU law, to examine a contention by the national authorities that a measure otherwise constituting a quantitative restriction within the scope of Article 34 TFEU is justified as a derogation, in the interests of the protection of human health, under Article 36 TFEU, to what extent is the national court required, or entitled, to form — on the basis of the materials before it — an objective view of the effectiveness of the measure in achieving the aim which is claimed; the availability of at least equivalent alternative measures less disruptive of intra-EU competition; and the general proportionality of the measure? (5) In considering (in the context of a dispute as to whether a measure is justified on grounds of the protection of human health under Article 36 TFEU) the existence of an alternative measure, not disruptive, or at least less disruptive, of intra-EU trade and competition, is it a legitimate ground for discarding that alternative measure that the effects of that alternative measure may not be precisely equivalent to the measure impugned under Article 34 TFEU but may bring further, additional benefits and respond to a wider, general aim? (6) In assessing whether a national measure conceded, or found, to be a quantitative restriction in the sense of Article 34 TFEU for which justification is sought under Article 36 TFEU and in particular in assessing the proportionality of the measure, to what extent may a court charged with that function take into account its assessment of the nature and extent to which the measure offends as a quantitative restriction offensive to Article 34 TFEU?’
