(a) the effect of the determination, whenever made, of an appeal by virtue of this Schedule to a Commissioner or the court ( the relevant determination) is that the relevant authority's decision out of which the appeal arose was erroneous in point of law; and

(b) after the date of the relevant determination a decision falls to be made by a relevant authority in accordance with that determination (or would, apart from this paragraph, fall to be so made)—

(b) is one made in pursuance of paragraph 17(3) or (5).

(3) In so far as the decision relates to a person's entitlement to benefit in respect of a period before the date of the relevant determination, it shall be made as if the relevant authority's decision had been found by the Commissioner or court not to have been erroneous in point of law.

(4) Sub-paragraph (1)(a) shall be read as including a case where—
