AI confidence in this short overview: high
This appeal concerned ESL's claim for R&D tax relief for two periods; HMRC issued closure notices disallowing the claims. The Tribunal found ESL did undertake practical innovation but did not prove the activities met the BEIS/statutory R&D definition (advance in overall scientific/technological knowledge/capability) nor that claimed expenditure was attributable to qualifying R&D. The appeal was dismissed.
Ratio decidendi
This summary is intended to identify the ratio decidendi, meaning the legal reasons for deciding and the binding part of the decision.
AI confidence in this ratio decidendi summary: high
Practical problem‑solving and experimentation within a company's operations are not R&D for tax relief under the BEIS Guidelines unless directed to achieving an advance in overall scientific or technological knowledge or capability or resolving identified scientific/technological uncertainty; the claimant bears the burden of proving both that activities meet that definition and the amount of qualifying expenditure, and lack of contemporaneous records may limit the claimant’s ability to discharge that burden.
Obiter dicta
This summary is intended to identify obiter dicta, meaning observations made by the way that were not necessary to deciding the case and are not binding.
AI confidence in this obiter dicta summary: medium
The Tribunal observed that a project need not succeed to qualify as R&D if there was an intention and plan to resolve scientific/technological uncertainty, but documentary evidence or detailed explanation is normally expected; it also noted leased plant/machinery is unlikely to qualify as consumables for R&D relief and care is needed to avoid double relief under other tax regimes.
