I am asking about legal rights?

Kitzinger and Wilkinson argue that their marriage fulfils these requirements even though people cannot legally enter into same-sex marriages in the UK. Under the Civil Partnerships Act 2004, which came into effect on December 5, 2005, same-sex couples are able to register their partnerships and receive all of the legal benefits previously available exclusively to opposite sex married couples. Wilkinson and Kitzinger reject civil partnerships, believing them to be both symbolically and practically a lesser substitute. They are asking the court to recognise their overseas marriage in the same way that it would recognise that of an opposite sex couple. They argue that a failure to do so constitutes a breach of their human rights to privacy and family life and their right to marry, and is discriminatory on the basis of their sexuality.
