Intention can be inferred in many ways by the courts．Thus the discharge at Cadiz instead of Bombay“for nefarious reasons”was an unreasonable deviation．A transshipment was declared to be an unreasonable deviation “since no excuse has been proffered for the deviation．” A geographic deviation abrogated the contract because“there can be no suggestion that the deviation was other than voluntary．”

On the other hand，where the court was unable to find that a defendant&39;s action constituted“a voluntary deviation without reasonable cause，” the defendant was exculpated of liability．The vast majority of decisions require that intention be proved in cases of deviation and quasi-deviation．The carrier has the burden of proving that it had no intention to deviate or that the deviation was not for the carrier&39;s sole benefit．

Accordingly，a geographic deviation due to an erroneous change of course by the master is not a deviation，but an error in navigation；in such a case，the carrier is protected under the Rules．If，however，the master is ordered to alter the customary or planned route，or deliberately takes it upon himself to do so，for a reason other than to save persons or cargo（or some similar reason），then the course alteration is an unreasonable deviation，because it is intentional and for the carrier&39;s own benefit．
