Legal Principles
Group Litigation Orders (GLOs): Judgments on GLO issues are binding on all claims on the register unless the court orders otherwise (CPR 19.12).
CPR 19
Limitation Act 1980, s32(1)(c): Extended limitation period for claims based on mistake of law; constructive discovery date is when a worthwhile claim was discovered or could reasonably have been.
Limitation Act 1980
Restitutionary remedy for tax paid under mistake of law; FII SC2 overruled DMG regarding constructive discovery date.
FII SC2
No restitutionary remedy for unlawful ACT utilised against lawful MCT (Prudential SC).
Prudential SC
EU law precludes domestic legislation preventing carry-forward of unused DTR credits resulting in unjustified discriminatory treatment of foreign-sourced dividends (FII SC3, Salinen).
FII SC3, Salinen
Claim in restitution for tax paid due to inability to offset unused DTR credits; three elements: enrichment, at claimant’s expense, and unjust.
Samsoondar v Capital Insurance Co Ltd [2020] UKPC 33
Outcomes
Limitation Issue: Claimants' claims were not conclusively established as in time due to Prudential HC; date of constructive discovery must be determined under FII SC2.
Henderson J in Prudential HC did not determine a specific date of constructive discovery, only that the claims were in time under DMG; FII SC2 changed the law on constructive discovery.
Set-off Issue: Claimants are not entitled to restitution for unlawful ACT utilised against lawful tax.
Prudential SC overruled Sempra Metals, holding no restitutionary remedy is available for utilised ACT.
Pleading Issue: Claimants pleaded a valid claim in restitution for unlawful tax paid due to inability to offset unused DTR credits.
Pleadings sufficiently identified the elements of unjust enrichment; any lack of particularisation was subsequently cured.
Issue C(ii): Paragraph 51(6) of Schedule 18 of the Finance Act 1998 does not apply.
Claims were made before April 1, 2010.
Issue C(iii): AXAIUK is entitled to restitution for indirect double taxation on dividends, subject to time limits.
HMRC's notional reconstruction of AXAIUK's tax computation was inconsistent with FII SC3; focus should be on actual tax paid due to the mistaken belief that DTR credits could not be carried forward.
