"Subject to the provisions of this Order, a person who has travelled from another Member State shall on entering the United Kingdom be relieved of excise duty on the fuel and lubricants contained in a commercial vehicle that he has with him"
"The reliefs afforded by this Order apply only to fuel that - [a] is contained in the vehicle's standard tanks; and [b] is being used or is intended for use by that vehicle"
"The Tribunal should remember that its primary task is to find the correct amount of tax, so far as possible on the material properly available to it the burden resting on the taxpayer. In all but very exceptional cases, that should be the focus of the hearing, and the Tribunal should not allow it to be diverted into an attack on the Commissioner's exercise of judgment at the time of assessment."
