Mr. Speaker, there are two main reasons. The first is that the government guarantees the benefits of employees past and present. The second is that the government absorbs all the pension fund deficits and takes all the risks.
The retirees association is itself in agreement that, legally the surpluses belong to the government, and I quote their website:
The association does not believe that it has any legal grounds to pursue a court case. A legal decision would not be in favour of the association since the legal advice provided to the association by independent experts in the pension field has been that the employer can decide on the disposition of the surplus.
