Abstract
The article – which takes its cue from a recent book by G. Zanetti – aims at analysing the debate on the recognition of sexual orientation equality in Constitutional cases. In particular, it analyses the transition of constitutional courts from the recognition of the right of privacy of gays and lesbians to the affirmation of the valuability of same-sex couples and their equality and dignity in relation to marriage. The article also emphasises how constitutional courts contribute to the solution of social and political conflicts on LGBT rights.
