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 aceording 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 Hardwicke 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.
