A person is quilty of an offence who, for the purpose of the sale or advertisement of any milk, refers to that milk by any such description, not being a special designation, as is calculated falsely to suggest—
In any proceedings taken under subsection (2) it rests on the person charged to prove the truth of any suggestion which, in the court's opinion, his acts or conduct, as proved by the prosecution, are or is calculated to convey.
Where there has been a breach of a condition subject to which a licence authorising the use of a special designation is granted, but the licence has not been revoked or suspended, the breach shall not be treated as rendering the use of the designation unauthorised for any of the purposes of this section or of any other provision of this Act.
Section 47 applies for the interpretation of the references in this section to selling milk, but as if the definition of milk in that section were omitted.
