"A person commits an offence if he -- (a) intentionally obstructs a person in the exercise of his powers under this section . . . Section 2 of the Police and Criminal Evidence Act is also material in this case. It provides, in so far as is material: "(2) If a constable contemplates a search, other than a search of an unattended vehicle, in the exercise . . . (b) of any other power, except the power conferred by section 6 below and the power conferred bysection 27(2) of the Aviation Security Act 1982 -- (i) to search a person without first arresting him . . . it shall be his duty, subject to subsection (4) below, to take reasonable steps before he commences the search to bring to the attention of the appropriate person . . . (ii) whether he is in uniform or not, the matters specified in subsection (3) below; and the constable shall not commence the search until he has performed that duty. (3) The matters referred to in subsection (2)(ii) above are -- (a) the constable's name and the name of the police station to which he is attached; (b) the object of the proposed search; (c) the constable’s grounds for proposing to make it; and (d) the effect of section 3(7) or (8) below, as may be appropriate."
"The co-operation of the person to be searched must be sought in every case, even if the person initially objects to the search. A forcible search may be made only if it has been established that the person is unwilling to co-operate or resists. Reasonable force may be used as a last resort if necessary to conduct a search or to detain a person or vehicle for the purposes of a search."
"It seems to us that if these particular provisions are thought not to be applicable to the present position, then it is for Parliament to look at those words again . . . Parliament decided that was necessary and, in our view, it is for us merely to apply the law."
