Questions referred

Does EU law and, in particular, the common rules governing the internal market in electrical energy and natural gas and the principles of legal certainty and protection of legitimate expectations allow retroactive application of the criteria for determining the amount of the reimbursements payable to former concession holders, thereby affecting previous contractual relationships, or can such application be justified, also in the light of the principle of proportionality, by the need to protect other public interests of European importance, relating to the necessity of improving protection for competition within the market in question and of affording greater protection to service users, who might indirectly bear the burden of an increase in the sums payable to former concession holders?
