“27(1) Subject to paragraph (2), section 83(1) of the Act (persons of pensionable age) does not apply where — (a) C has reached the relevant age and is entitled to an award (“the original award”) of either or both components pursuant to an exception in regulation 25 or 26; and (b) that award falls to be revised or superseded. (2) Where the original award includes an award of the mobility component and is superseded for a relevant change of circumstance which occurred after C reached the relevant age, the restrictions in paragraph (3) apply in relation to the supersession. (3) The restrictions referred to in paragraph (2) are — (a) where the original mobility component award is for the standard rate then, regardless of whether the award would otherwise have been for the enhanced rate, the Secretary of State - (i) may only make an award for the standard rate of that component; and (ii) may only make such an award where entitlement results from substantially the same condition or conditions for which the mobility component in the original award was made. (b) where the original mobility component award is for the enhanced rate, the Secretary of State may only award that rate of that component where entitlement results from substantially the same condition or conditions for which the mobility award was made. (4) Where the original award does not include an award of the mobility component but C had a previous award of that component, for the purpose of this regulation entitlement under that previous award is to be treated as if it were under the original award provided that the entitlement under the previous award ceased no more than 1 year prior to the date on which the supersession takes or would take effect.”
“In my view, all grounds of supersession can apply in so far as the conditions they contain are made out, without any artificial rules to try to make them mutually exclusive. So far as decisions that are advantageous to the claimant go, there is then no difficulty in applying a general principle that the claimant should be able to take the benefit of whatever ground gives the most advantage. So far as decisions that are not advantageous to the claimant are concerned, which will in the great majority of cases be supersessions carried out at the Secretary of State’s own initiative, I do not see why the same principle cannot apply. The Secretary of State is entitled to rely on whatever of the grounds of supersession that are made out that result in what he says is the correct position being applied for the longest period. But if the Secretary of State chooses to rely on the simpler ground of supersession in regulation 26(1)(a), without going to all the bother of investigating and thinking about what the claimant should or should not have realised needed to be notified in the past, and is content for the superseding decision to take effect from the date on which it is made, I do not see why on appeal a tribunal should be obliged to consider all the elements of and under regulation 23(1) on relevant change of circumstances first.”
