A case is being brought before the Supreme Court to determine whether Mr Walker's husband should be entitled to a full widow's pension, as would be the case if he was married to a woman. It is argued that not allowing this to be the case is a breach of Mr Walker's human rights and is discriminatory. 

The outcome of this case may have an effect on the way pensions are divided on the breakdown of same sex marriages and the provisions that are made available and considered when resolving financial claims.

It will be interesting to see the approach taken by the Court in light of the recent decision to allow a cohabitee to claim against her partner's pension.
