Any person who contravenes section 3 or 4 shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $1,000 and for a second or subsequent offence shall be liable to a fine not exceeding $2,000 or to imprisonment which may extend to 6 months or to both.

No proceedings shall be taken under this section without the previous sanction in writing of the President of the Board.

In any prosecution for an offence under this section it shall be a good defence if it is proved to the satisfaction of the court that the accused had reasonable grounds for believing that he was not acting in contravention of section 3 or 4, as the case may be.
