On the present occasion, my lords, I pronounce with the utmost confidence, as a maxim of indubitable certainty, _that the publick has a claim to every man's evidence_, and that no man can plead exemption from this duty to his country. But those whom false gratitude, or contracted notions of their own interest, or fear of being entangled in the snares of examination, prompt to disappoint the justice of the publick, urge with equal vehemence, and, indeed, with equal truth, that _no man is obliged to accuse himself_, and that the constitution of Britain allows no man's evidence to be extorted from him to his own destruction. Thus, my lords, two of the first principles of the British law, though maxims equally important, equally certain, and equally to be preserved from the least appearance of violation, are contradictory to each other, and neither can be obeyed, because neither can be infringed. How then, my lords, is this contradiction to be reconciled, and the necessity avoided of breaking the law on one side or the other, but by the method now proposed, of setting those whose evidence is required, free from the danger which they may incur by giving it. The end of the law is the redress of wrong, the protection of right, and the preservation of happiness; and the law is so far imperfect as it fails to produce the end for which it is instituted; and where any imperfection is discovered, it is the province of the legislature to supply it. By the experience, my lords, of one generation after another, by the continued application of successive ages, was our law brought to its present accuracy. As new combinations of circumstances, or unforeseen artifices of evasion, discovered to our ancestors the insufficiency of former provisions, new expedients were invented; and as wickedness improved its subtilty, the law multiplied its powers and extended its vigilance. If I should, therefore, allow, what has been urged, that there is no precedent of a bill like this, what can be inferred from it, but that wickedness has found a shelter that was never discovered before, and which must be forced by a new method of attack? And what then are we required to do more than has been always done by our ancestors, on a thousand occasions of far less importance? I know not, my lords, whether it be possible to imagine an emergence that can more evidently require the interposition of the legislative power, than this which is now proposed to your consideration. The nation has been betrayed in peace, and disgraced in war; the constitution has been openly invaded, the votes of the commons set publickly to sale, the treasures of the publick have been squandered to purchase security to those by whom it was oppressed, the people are exasperated to madness, the commons have begun the inquiry that has been for more than twenty years demanded and eluded, and justice is on a sudden insuperably retarded by the deficiency of the law.
