to an offence of public nuisance but the few employees whose day was disrupted were not a sufficiently wide class of the public. But in R v Norbury (1978) Crim. LR 435 the defendant made 605 obscene telephone calls to 494 different women over a period of four years. This repetitive behaviour over a long period, intended to cause offence and alarm, was held the kind of behaviour which the public has an interest in condemning. This is not without its problems because each telephone call lacks the element of common injury. As a comparison, the cases of R v Ruffell (1991) 13 Cr. App. R. (S) 204 and R v Shorrock (1994) QB 279 involved the prosecution of the organisers of "acid house" parties at night in fields adjacent to residential accommodation with liability confirmed because they knew, or ought to have known, that there was a real risk of creating the sort of nuisance that in fact occurred. At each party there was major traffic disruption and the noise of music, with clean-up operations required the following day. While R v Ong (2001) 1 Cr. App. R. (S) 404 involved a betting scam in which the floodlights at a Premier Division football match between Charlton Athletic and Liverpool were to be sabotaged which was inherently dangerous to the thousands within the ground. In R v Soul (1980) 70 Cr. App. R. 295 a group who agreed to secure the unlawful release of a restricted Broadmoor patient was convicted of conspiracy to effect a public nuisance. The court seems to have assumed that the public would have been exposed to danger had the plan been put into effect. That the Crown had failed to prove any actual danger or common injury was not considered (see the critical commentary at (1980) Crim. LR 234 suggesting that the courts were improperly reintroducing "public mischief" into the law despite the ruling by the House of Lords in R v Withers (1975) AC 842). Similarly, in R v Millward (1986) 8 Cr. App R(S) 209 the defendant made hundreds of telephone calls (636 in a single day) to a young woman police officer with whom he had become infatuated, at the police station where she worked. As to the requirement of common injury, Glidewell LJ said: In R v Johnson (Anthony) (1997) 1 WLR 367, the Court of Appeal confronted the problem head-on.
