1. Comparative reasoning and consistent interpretation techniques led to a new interpretation of the constitutional principle of equality under the ECHR.
The ECtHR has interpreted Art. 12 ECHR in light of Art. 9 of the EU Charter. The open intention of this operation was to extend the scope of the right to family life. This comparative technique led to the declaration that same-sex marriage is, if not a right proper, a lawful option under the ECHR.
The Italian Supreme Court, recalling expressly its duties of consistent interpretation vis-à-vis ECtHR’s case-law and EU law, has overtly modified a long-established interpretation of a fundamental right, providing a new reading to the constitutional provision on non-discrimination (Art. 3), looking at the ECtHR’s use of Art. 14 and 8 of the ECHR.
2. Comparative reasoning /Spill-over effect?. Indirect judicial interaction between the Constitutional Courts
Although the Italian Supreme Court did not quote any (national) foreigner precedents, it was plausibly aware of the rulings that its foreign colleagues had been issuing in the previous years. For instance, in 2011 the German Federal Constitutional Court declared the discriminatory effect of the domestic rule preventing two people of different sex from registering their civil partnership when one of them was a transgender who had not undergone surgery. Even though they could perceive themselves as a same-sex couple, the unconstitutional regulation previously in force made only marriage available to them, and reserved civil partnership to same sex-couples (Federal Constitutional Court of Germany, judgment of 11 January 2011, 1 BvR 3295/07). Before that, on 21 July 2010, the German Constitutional Court declared the unconstitutionality of domestic regulations that imposed a higher fiscal burden on civil partnerships, compared to married couples (Federal Constitutional Court of Germany, order of 21 July 2010 – 1 BvR 611/07, 1 BvR 2464/07). The Bundesverfassungsgericht recalled, inter alia, that differential treatment must be based on objective criteria of difference that make two situations not comparable, and cannot be justified only based on a generic reference to the State’s duty to protect marriage and family life. On an issue closer to the one ruled by the Italian Supreme and Constitutional Courts, see the decision of the Portuguese Constitutional Court of 9 July 2009, ruling that the Constitution does not require (nor prevents) recognition of same-sex relationships (Portuguese Constitutional Court, Acórdão no. 359/2009 of 9 July 2009, with a dissent of two judges, who favored the idea of a constitutional right to marriage for same-sex couples). On 28 January 2011, instead the French Conseil Constitutionnel held that the ban on same-sex marriage in France was not unconstitutional (Décision n° 2010-92 QPC du 28 janvier 2011, M.me Corinne et autres) since, inter alia, it did not encroach upon the fundamental right to enjoy family life granted to everyone, regardless of the right to marry.
3. Impact on the national case-law/jurisprudence
After the judgment of the Italian Supreme Court of 2012, Italian judges can safely refer to the
obiter dicta of the Supreme Court, and investigate whether certain specific same-sex couples’ rights have a EU-law dimension (for instance, on the freedom of movement). If so, that link can be used to
apply the EU Charter directly, or to raise a
preliminary question to the CJEU, in the attempt to instigate an evolutionary trend. Some tribunals have already found that the provision of Art. 2(2)(a) of the Citizens’ Directive 2004/38, which includes the citizen’s “spouse” among the members of his family (who enjoy rights of residence under Art. 7) cannot be interpreted solely to include different-sex spouses, as long as there is a valid marriage celebrated in one Member State (cf. see Italian Supreme Court, Criminal section (I), judgment no. 1328, 19 January 2011.
