321Exclusion of extended prescriptive period in ScotlandU.K.
(1)Section 6(4)(a)(ii) of the Prescription and Limitation (Scotland) Act 1973 (c. 52) (extinction of obligations by prescriptive period: exclusion of period during which creditor induced by error to refrain from making claim) does not apply in relation to an obligation based on redress of unjustified enrichment arising from an error of law relating to a taxation matter under the care and management of the Commissioners of Inland Revenue.
(2)Subsection (1) has effect in relation to an obligation in respect of which no relevant claim has been made before 8th September 2003.
(3)In the case of a relevant claim made on or after that date and before the passing of this Act relating to an obligation that would have been extinguished if subsections (1) and (2) had been in force—
(a)proceedings on the claim (or so much of the proceedings as relates to such an obligation) shall be deemed to be discontinued on the passing of this Act, and
(b)any payment made by the Commissioners in or towards meeting their liability on the claim (or so much of it as so relates) may be recovered by them (with interest from the date of the payment).
(4)The provisions of this section apply in relation to any relevant claim for redress of unjustified enrichment arising from an error of law, whether expressed to be made on the ground of error or on some other ground.
(5)In this section “relevant claim” has the same meaning as in section 6 of the Prescription and Limitation (Scotland) Act 1973.
