R (Good Law Project Ltd) v Health Secretary (CA) [2022] 1 WLR
Principles of estoppel by convention require an expressly shared common assumption, responsibility assumed by the estopped party, reliance by the alleging party, subsequent mutual dealing, and sufficient detriment or benefit.
Tinkler v Revenue and Customs Commissioners [2021] UK SC 39
HMRC's assertion that service was defective was rejected.
The court found that while service wasn't strictly compliant with the Press Release, the claimant took reasonable steps based on a reasonable interpretation of ambiguous guidance, and HMRC suffered no significant detriment beyond losing a limitation defense. The court exercised its discretion under CPR 6.15 to validate service.
Permission to proceed with the substantive claim was granted.
The court found the Claimants' arguments regarding the interpretation of "voluntary restitution" to be arguable.
