An injunction was obtained against Bob for allegedly disrupting/sabotaging the Epsom Derby Jockey Club, prohibiting him from doing such things again in the future. He violated this injunctive prohibition of the court, thereby placing himself in contempt of court, for which he may be subject to committal proceedings.
What process could such proceedings be initiated by, and who would be able to initiate it? Further, what parties would most typically be the ones to instigate it?
