Britain's top court said last Wednesday it was unable to agree on the case of a transgender woman who was denied a female pension because she refused to divorce her wife.

Five Supreme Court judges said the Court of Justice of the European Union must decide the case.

The claimant, who is now 68, applied for her state pension at age 60 in 2008, but was refused because she did not hold an official "gender recognition certificate". She was told she would have to wait till 65, the age for men.
