“3. Critical Mass is not an organisation but the name given to a recurrent event. Since April 1994 in London, as in many other cities throughout the world, starting in San Francisco in 1992, cyclists have gathered at a set time early in the evening of the last Friday of each month for a mass ride through the streets. In London they gather on the South Bank near the National Film Theatre. These features are fixed, but the route is not. Whoever happens to be at the front decides which direction to take next. The numbers, which rarely if ever fall below 100 and are commonly three or four times that, are sufficient to make their presence felt both by passers-by and by other road users, the great majority of whom are motorists. They can and do cause additional congestion, but they keep moving (we are not concerned here with questions of obstruction if and when they halt) and can legitimately say that they are part of the city’s traffic. 4. …. Pauses are sometimes held to mark places where cyclists have been killed in collisions, and occasionally a segment will make for a particular venue such as an embassy to demonstrate in response to political events. However, the police identify two particular kinds of objective which they have observed the group making for: places where maximum disruption to vehicular traffic can be caused, such as Piccadilly Circus and Oxford Street, and places where cyclists are considered to get a hard time from motor vehicles, such as Euston Road and Blackfriars Bridge, making the Critical Mass event a form of payback. The claimant, who has been involved in these rides since their early days but is otherwise a nominal party, rejects this as an account of his (and most other riders’) motivation, which is, he says, simply to celebrate cycling.”
“If at any time the Commissioner of Police for the City of London or the Commissioner of Police of the Metropolis reasonably believes that, because of particular circumstances existing in his police area or part of it, the powers under section 12 will not be sufficient to prevent the holding of public processions in that area or part from resulting in serious public disorder, he may with the consent of the Secretary of State make an order prohibiting for such period not exceeding 3 months as may be specified in the order the holding of all public processions (or of any class of public procession so specified) in the area or part concerned.”
“Thus advance notification of a procession will enable the police to consider exercising their powers to impose conditions on it or to prohibit it. But it is not suggested either that this is the purpose of s.11 or that the applicability of s.11 is determined or conditioned by the availability of such controls. The control powers in sections 12 and 13 apply to any procession, notifiable or not, if the circumstances indicate a material threat of disorder or intimidation. The purpose of s.11 is to permit the policing of processions which pose no such threat as well as of those which do. ”
“If the police consider that they can prove all the other ingredients of an offence of non-notification, they must find an organiser to prosecute under s.11(7). If there is no organiser, or if they cannot prove that the accused organised the procession, they will not be able to obtain a conviction. But it is not for this court to say that there can never be such a prosecution. Whether there can be will depend in each case on whether the police can prove the accused to have organised the procession, whether from the start or during its progress (see, as much for its historical as for its legal interest, Flockhart v Robinson[1950] KB 498 ). ”
“We have accepted that it is by its intention that a notifiable procession is defined, so that an event which has remained constant in form but has changed in intention may arguably cease to be common or customary within the meaning of s.11(2). We have also declined to define the intention of the present-day Critical Mass event beyond holding that it does not necessarily fall outside s.11(1). But on the evidence before us we see no ground for holding that the dominant collective intention has significantly changed over time.”
“27. Our first reason is that an unbroken succession of over 140 of these collective cycle rides, setting out from a fixed location on a fixed day of the month and time of day and travelling, albeit by varying routes, through the Metropolitan Police area, cannot by now sensibly be called anything but common or customary. Our second reason is that the absence of a planned route for the procession has no legal consequences if notice of the procession is not required. Our third reason is that the procession is not prevented from having acquired a common or customary character by the unproven possibility that one or more individuals failed to give notice under s.11 of the first such rides some twelve years ago. 28. We reach this conclusion in the knowledge that not having advance notice of the intended route of a procession does not make the job of policing it any easier. But the legislation itself creates only a selective requirement of notice. It was passed against a background of reluctance to place prior restrictions on the exercise of a historic liberty: Lord Scarman had advised against doing so in his 1974 report on the Red Lion Square disorders, but in his 1981 report on the Brixton disorders had reluctantly changed his mind. It continues to have to be construed and applied within a common law system which not only reads penal legislation narrowly but is concerned to protect people’s right to use the streets for lawful purposes, whether singly or in groups, without official permission and without having to account for their intentions except to the extent that Parliament has clearly stipulated otherwise.”
“In the past two years the monthly event has not created any serious public order problems”, one reason for which, he says, is: “ …. the firm but fair approach of the police recognising not only the participants’ right to demonstrate but also preventing the public’s inconvenience as far as is possible. ”
