Environment – Protection. The Divisional Court dismissed the appellant Environment Agency's appeal against the Crown Court's decision, allowing the respondent houseboat owners' appeals against their convictions for keeping an unregistered vessel on a waterway. A 'vessel', under art 2 of the Environment Agency (Inland Waterways) Order 2010, SI 2010/699, was something 'constructed or used' either to 'carry' people or things, or to be 'propelled or moved' across or through the water and the houseboats were not 'vessels'.
