operation if correct, I propose to indicate. It would have been
inconsistent with acknowledged rules, because it is admitted that, at least, protection may be given when it is afterwards claimed on oath. But when that stage arrives the Court does not ask who the prosecutor is likely to be, and then distinguish according as it is the Attorney-General or a common informer. And why should it adopt any different course merely because it acts at an earlier stage ? Then as to the authorities and precedents. In 1736 Lord Chancellor Hardwieke in Smith v. Read 1 said:- "There is no rule more established in equity, than that a person shall not be obliged to discover what will subject him to a penalty, or anything in the nature of a penalty," and the Lord Chancellor added, "Under the rule, a man is not obliged to accuse himself, is implied, that he is not to discover a disability in himself." A plea to a bill of discovery was on those grounds allowed. And SO in the succeeding case of Harrison v. South- cote (2). Hare on Discovery (1836), p. 131, says :- If the answer of the defendant might be evidence tending to subject him to punishment by any judicial or competent authority, or to any penalty or forfeiture, or disability in the nature of a penalty, the defendant will not be compelled to make the discovery." This is in accordance with what is cited in Mitford on Pleading, 5th ed., pp. 229-230, and Daniell's Chancery Practice, 6th ed., p. 1852.
In the same year, 1836, Lord Langdale M.R. decided Glynn V. Houston 3, allowing a demurrer to a bill for discovery in aid of an action for damages for assault and false imprisonment. The demurrer was allowed on the ground that the discovery was sought of matters, which, if established, would have subjected the defendant to penal consequences. The Master of the Rolls said :- " In what way he would be SO subject, whether by indictment, information, impeachment, or, if necessary, by a bill of pains and penalties, is immaterial. It is sufficient that he would be subject to penal consequences." He quotes in support what Sir Anthony Hart said in another case that every statement of fact in every bill is either conducive to the general result, or it is unimportant
