Men’s minds were much exercised as to this meeting. Petitions, signed by upwards of 16,000 persons in the metropolis against the proposed demonstration in the Park, were presented to Mr. Walpole; and the question of the law on the subject was authoritatively laid down; which was, that in November, 1856, the law advisers of the Crown--Sir Alexander Cockburn, Sir Richard Bethell, and Mr. (afterwards Justice) Willes--signed an opinion to the effect that there is a right to close the gates and exclude the public: or, the gates being open, to exclude persons; but that persons who have once entered, cannot be turned out without notice that the license is withdrawn. In July, 1866, this opinion was submitted to Sir William Bovill and Sir Hugh (afterwards Earl) Cairns, who were particularly requested to say whether there was any legal authority to disperse by force any meeting for political purposes in the Park. Their answer was, that there is no such authority for any practical purpose. They stated that when persons had once entered the Park, they could only be ejected after notice being served on, or brought home to each individually. Publication, they said, is not enough, for many cannot, and many would not read, and an express warning must be shown. They particularly impressed that the right of removal is a separate right against each individual who has had notice. No force, therefore, can be brought to bear against bodies, or masses, which may contain many who have not had notice. They also said that it would not be practicable to remove any number, individually, and prevent them from returning, and remarked on the probability of disorder, if even an individual were turned out. The effect, consequently, was that the Government had nothing but the common law of trespass to rely upon. The Government, however, relied upon the strong arm; and on May 6th special constables were sworn in in different parts of London, whilst the several police magistrates were in attendance at their Courts for a like purpose. The public were officially warned that a force of over 5000 mounted and foot police would be in the Park, as well as Sir Thomas Henry, the Chief Magistrate, upon whose word would rest the employment of troops, who were, for that day, confined to barracks, in order to be in readiness at a moment’s notice. But the futility of guarding the railings and hoardings of the whole Park was so forcible that it was determined not to attempt to keep anybody out; and, at the last moment, it was decided to permit the demonstration, and not to interfere with it, so long as the peace was preserved.
