1 By order of 30 May 1988, which was received at the Court on 6 December 1988, the Tribunale Amministrativo Regionale del Lazio referred to the Court for a preliminary ruling under Article 177 of the EEC Treaty a question on the interpretation of Articles 30 and 92 of the EEC Treaty in order to enable it to assess the compatibility with those provisions of Italian legislation reserving a percentage of public supply contracts to undertakings established in the Mezzogiorno.
2 The question arose in proceedings between Laboratori Bruneau Srl and Unità sanitaria locale RM/24, Monterotondo (Rome) (hereinafter referred to as "USL"), following its exclusion from the tendering procedure for a contract to supply suturing material.
3 Under Article 17(16) and (17) of Law No 64 of 1 March 1986 ("Disciplina organica dell' intervento straordinario nel Mezzogiorno", a system of rules governing special aid for Southern Italy), the Italian State extended to all public bodies, authorities, and bodies and companies in which the State has a shareholding, including local health authorities situated throughout Italy, the obligation to obtain at least 30% of their supplies from industrial, agricultural and small craft undertakings established in Southern Italy in which the products concerned undergo processing.
4 In accordance with the provisions of the national legislation, USL laid down the conditions governing a restricted tendering procedure for the supply of suturing material. Laboratori Bruneau Srl challenged that decision before the Tribunale Amministrativo Regionale del Lazio on the ground that it had been excluded from the restricted tendering procedure for the contract as it was not established in the Mezzogiorno.
5 In the course of its consideration of the application, the national court decided to request the Court of Justice to give a preliminary ruling on the following question: "Whether, firstly, Articles 30 and 92 of the EEC Treaty must be interpreted as meaning that national rules reserving a percentage of public supply contracts to undertakings located in particular regions of national territory constitute measures of equivalent effect to quantitative restrictions or 'aids' and, secondly, whether they preclude such rules?"
6 Reference is made to the Report for the Hearing for a fuller account of the facts of the case, the relevant provisions, the procedure and the written observations submitted to the Court.
7 In its judgment in Case C-21/88 Du Pont de Nemours Italiana v Unità sanitaria locale No 2 di Carrara [1990] ECR I-889, the Court, in reply to questions of identical scope from the Tribunale Amministrativo Regionale della Toscana, held first that Article 30 of the EEC Treaty must be interpreted as precluding national rules which reserve to undertakings established in particular regions of the national territory a proportion of public supply contracts, and secondly, that the fact that national rules might be regarded as aid within the meaning of Article 92 of the Treaty could not exempt them from the prohibition set out in Article 30 of the Treaty.
8 Since the observations made to the Court in the present case do not contain any element of fact or law which might lead to a different response, the reply given in the judgment in Case C-21/88, referred to above, must be repeated.
