(1)Where an adjudication officer has given a decision on a review under section 28(1) above, the claimant or such other person as may be prescribed may appeal—
(a)in prescribed cases, to a disability appeal tribunal; and
(b)in any other case, to a social security appeal tribunal.
(2)Regulations may make provision as to the manner in which, and the time within which, appeals are to be brought.
(3)An award on an appeal under this section replaces any award which was the subject of the appeal.
(4)Where a person who has been awarded a disability living allowance consisting of one component alleges on an appeal that he is also entitled to the other component, the tribunal need not consider the question of his entitlement to the component which he has already been awarded or the rate of that component.
(5)Where a person who has been awarded a disability living allowance consisting of both components alleges on an appeal that he is entitled to one component at a rate higher than that at which it has been awarded, the tribunal need not consider the question of his entitlement to the other component or the rate of that component.
(6)The tribunal shall not consider—
(a)a person’s entitlement to a component which has been awarded for life;
(b)the rate of a component so awarded; or
(c)the period for which a component has been so awarded,
unless—
(i)the appeal expressly raises that question; or
(ii)information is available to the tribunal which gives it reasonable grounds for believing that entitlement to the component, or entitlement to it at the rate awarded or for that period, ought not to continue.
