Beadle v HMRC [2020] EWCA Civ 562; Caerdav v HMRC [2023] UKUT 000179 (TCC)
A Tribunal lacks jurisdiction to consider legitimate expectation where HMRC has no discretion in assessing liability.
Caerdav v HMRC [2023] UKUT 000179 (TCC)
Appeals dismissed.
The cars were not 'pool cars' under ITEPA s 167; estoppel did not apply due to the statutory nature of the NIC liability and the 1993 agreement being ultra vires; the Tribunal lacked jurisdiction to consider legitimate expectation.
