“But how do we know?”
“1. The relevant Licence does not permit testing on animals of BT where the end use of the toxin is vanity (i.e. where its administration is not to address a recognised psychological or physiological condition). 2. The Licence holder must satisfy himself, prior to testing on animals, that the manufacturer has reasonable measures in place to ensure that a batch from which BT samples are tested on animals will be used only for medicinal purposes (i.e. to address a recognised psychological or physiological condition). 3. Similarly, the defendant’s duty is to ensure that the Licence holder has, prior to testing on animals, information showing that such measures are in place. 4. Provided such information is available at that time, the Licence holder would not be in breach of his Licence, and the defendant would not be a breach of her enforcement duty, simply because BT from a batch which the Licence holder has test on animals is later used for vanity purposes. For the avoidance of doubt, the existence of a marketing or clinical trial authorisation for the BT product in question does not by itself constitute a reasonable measure.”
