"In the King's Bench Division, before the Lord Chief-Justice, Mr. Justice Humphreys and Mr. Justice MaCNAGHTEN, on the 7th inst., the Court granted to Mr. Alan Patrick Herbert, of Hammersmith Terrace, W., a rule nisi for an order in the nature of mandamus under Section 5 of Jervis' Act, calling on Sir Rollo Graham Campbell, the Chief Magistrate, 15 members of the Kitchen Committee of the House of Commons, and Mr. Robert John Bradley, manager of the Refreshment Department of the House of Commons, to show cause why the Chief Magistrate should not hear and determine the matter of two applications for summonses by Mr. Herbert against the other respondents.
Mr. Monkton read an affidavit by Mr. Herbert, who deposed that on May 17th, 1934, counsel on his behalf applied to Mr. Fry, at Bow Street, for process against the members of the Kitchen Committee and Mr. Bradley on two informations alleging contraventions of Section 65 (1) of the Licensing (Consolidation) Act, 1910, by the unlawful sale by retail of intoxicating liquor at a refreshent room at the House of Commons on April 10th, 1934. One of the alleged unlawful sales was to Mr. Herbert himself, and the other to Mr. Victor Cazalet, M.P. On that occasion Mr. Fry said that the Chief Magistrate would like to deal with the matter himself. The application was accordingly renewed before the Chief Magistrate on May 22nd, when he intimated that, on the authority of Williamson v. Norris, he would have been prepared to grant summonses against the Kitchen Committee but for a further difficulty which he felt. That difficulty was stated by the Chief Magistrate in these words: —
Assuming for the purpose of this application that an offence may have been committed, are members of the House of Commons carrying out duties entrusted to them by the House, under the control of the House, in a way long practised and approved by the House, within the precincts of the House, amenable in this matter to the jurisdiction of this Court? Are they not protected by the privileges of the House and amenable only to the House of which they are members?
At the conclusion of counsel's argument the Chief Magistrate said that he was not satisfied that he had jurisdiction to grant the process applied for, but the matter could be raised by mandamus."

I love the Chief Magistrate's argument: the normal laws of the land don't apply to MP's in the House of Commons. Basically that they got to try and judge themselves.
