If, having considered a complaint about an advertisement pursuant to regulation 4(1) above, he considers that the advertisement is misleading, the Director may, if he thinks it appropriate to do so, bring proceedings for an injunction (in which proceedings he may also apply for an interlocutory injunction) against any person appearing to him to be concerned or likely to be concerned with the publication of the advertisement.

The Director shall give reasons for his decision to apply or not to apply, as the case may be, for an injunction in relation to any complaint which these Regulations require him to consider.
