Any operation necessary for the preservation of the beverages (decanting, pouring or lowering) is permitted during transport, but only in the presence of the agents of the administration, who will note this on the back of the consignments. If an accident of force majeure necessitates the rapid unloading of a vehicle or boat or the immediate decanting of liquids, these operations may take place without prior declaration, it being the responsibility of the driver to have the accident recorded by the agents or, in their absence, by the mayor or deputy mayor of the commune whose town hall is nearest.
