Paragraph 23
If the Agency considers that unless the licence is suspended there will or may be a risk of injury to health it may give notice in writing to the licensee suspending the licence from a date specified in the notice and, subject to sub-paragraphs (2) and (3), the licence shall have no effect for the purpose of these Regulations during that period.
Subject to sub-paragraph (3), where notice is given suspending the licence—
the suspension shall cease to have effect at the expiration of three days after notice of the suspension has been served on the licensee unless notice has in the meantime been served on the licensee under paragraph 20; but
if notice has in the meantime been served on the licensee under paragraph 20 the suspension shall continue until either—
the Agency decides not to cancel the licence; or
the licence terminates.
The Agency may, if it considers that in the absence of suspension there will not be a risk of injury to health, by further notice in writing to the licensee withdraw the notice suspending the licence.
