Birnberg Peirce Matrix Law | Seven Bedford Row

#BackTo60 is delighted to share the following legal statement from our legal team. 

Barristers Michael Mansfield QC (@nexuschambers) , Karon Monaghan QC and Catherine Rayner of counsel instructed by Marcia Wills Stewart QC (Hon.), Hilary Nelson and Maya Groves: full details of the judicial challenge will be published along with the Crowd Funder, in due course.

"There is consensus within the legal team that the pension policy implemented by successive governments in respect of women of a particular age group constitutes a gross injustice.


The impact on the economic, social and mental wellbeing of these women, who rightly enjoyed a perfectly legitimate expectation of satisfactory provision in retirement, has been devastating.

The extent of individual distress and hardship is only now becoming evident. It is deeply ironic that all of this is done in the name of equalisation and equality, when the very means employed to achieve this are themselves discriminatory.


It is intended that the current pension policy be subjected to both public and judicial scrutiny and, therefore, steps will be taken towards mounting a judicial challenge."
