Medcalf and Another v R Strawbridge Ltd The owner of a vehicle attached to his vehicle a skid-pan which did damage to the surface of an unadopted road. In an action by two of the frontagers to restrain the continued use of the skid-pan, the owner of the vehicle contended that, if what was being done amounted to a nuisance, it was a public nuisance and, the damages being common to all the subjects of the Crown, the Attorney-General alone could sue.
