4.—(1) If a senior police officer, having regard to the time or place at which and the circumstances in which any public procession is being held or is intended to be held and to its route or proposed route, reasonably believes that—
(a)it may result in serious public disorder, serious damage to property or serious disruption to the life of the community; or
(b)the purpose of the persons organising it is the intimidation of others with a view to compelling them not to do an act they have a right to do, or to do an act they have a right not to do, he may give directions imposing on the persons organising or taking part in the procession such conditions as appear to him necessary to prevent such disorder, damage, disruption or intimidation, including conditions as to the route of the procession or prohibiting it from entering any place specified in the directions.

(a)it may result in serious public disorder, serious damage to property or serious disruption to the life of the community; or
(b)the purpose of the persons organising it is the intimidation of others with a view to compelling them not to do an act they have a right to do, or to do an act they have a right not to do, he may give directions imposing on the persons organising or taking part in the meeting such conditions as to the place at which the meeting may be (or continue to be) held, its maximum duration, or the maximum number of persons who may constitute it, as appear to him necessary to prevent such disorder, damage, disruption or intimidation.
