The survivor benefit is essentially an insurance benefit that one gets because of the death of a spouse or, in the case of an orphan, the death of a parent. The fact that the contributions are paid by the individual and the employer is really for the retirement part of the plan. This legislation leaves unaffected the possibility of receiving one's own retirement entitlement based on one's own contribution. So in that sense I think, sir, it could be challenged but I don't think it would be a successful challenge.
