25. If a sheriff or justice of the peace is satisfied that—S
(a)there are reasonable grounds for the exercise in relation to any premises of a power under Part 1 of this Schedule; and
(b)one or more of the conditions specified in paragraph 26 is fulfilled in relation to those premises,
the sheriff or justice of the peace may by warrant authorise SEPA to designate a person to exercise the power in relation to those premises, in accordance with the warrant and, if need be, by force.

(a)that the exercise of the power in relation to the premises has been refused;

27. In a case where paragraph 25 applies, a justice of the peace or sheriff must not issue a warrant under this Schedule by virtue only of being satisfied that the exercise of a power in relation to any premises has been refused, or that a refusal is reasonably apprehended, unless that person is also satisfied that the notice required by paragraph 18 has been given and that the period of that notice has expired.S
