Division 3Variation and cancellation of authorities
20 When can an authority be varied?
(1)
The chief officer may vary an authority—
(a)
at any time on the chief officer's own initiative; or
(b)
on application under section 21.
(2)
However, an authority cannot be varied so as to extend its period of validity if the authority is—
(a)
an authority for a local minor controlled operation (whether formal or urgent); or
(b)
an urgent authority for a cross-border controlled operation or local major controlled operation.
(3)
Also, an authority cannot be varied unless the chief officer is satisfied on reasonable grounds that the variation will not authorise a significant alteration of the nature of the authorised operation concerned.
