“Any thing liable to forfeiture under the customs and excise Acts may be seized or detained by any officer or constable or any member of Her Majesty’s armed forces or coastguard.”
“ …..there is a clear reason why Parliament wished to create a distinct power of detention, namely to allow for the goods to be held where there is uncertainty whether duty has been paid on them or not, to allow for investigations to be carried out before HMRC decide whether to seize the goods or return them.”
“In the particular context in which section 139(1) applies, I do not think that it is an abuse of language to describe goods detained where there are reasonable grounds for suspecting that duty might not have been paid on them as goods "liable to forfeiture", in the sense that they are liable to forfeiture if, at the end of the process of examination contemplated by the Act as set out in Schedule 3 (first by HMRC, then by a court), that suspicion proves to be correct.”
“Any thing liable to forfeiture under the customs Acts may be seized .. by an officer.. whenever he has reasonable grounds to believe that they are liable to forfeiture and may be detained ..by an officer…whenever he has reasonable grounds to suspect that they may be liable to forfeiture.”
