"In another context, the European Court of Human rights has interpretedArticle 12 of the Convention [the right to marry] as applying only to the traditional marriage between two persons of the opposite biological sex ..… It follows that, in the present state of the law within the Community, stable relationships between two persons of the same sex are not regarded as equivalent to marriages or stable relationships outside marriage between persons of opposite sex. Consequently, an employer is not required by Community Law to treat the situation of a person who has a stable relationship with a partner of the same sex as equivalent to that of a person who is married to or has a stable relationship outside marriage with a partner of the opposite sex."
