I readily admit that the law which requires presumption or custom to be carried back for a period of nearly 700 years, is a bad and mischievous law, … - Sir Alexander Cockburn, 12th Baronet

I think the old, sound, and honest maxim that "you shall not do evil that good may come," is applicable in law as well as in morals.

Whatever disadvantages attach to a system of unwritten law, and of these we are fully sensible, it has at least this advantage, that its elasticity enables those who administer it to adapt it to the varying conditions of society, and to the requirements and habits of the age in which we live, so as to avoid the inconsistencies and injustice which arise when the law is no longer in harmony with the wants and usages and interests of the generation to which it is immediately applied.

In a criminal proceeding the question is not alone whether substantial justice has been done, but whether justice has been done according to law. All proceedings in poenam are, it need scarcely be observed, strictissimi juris; nor should it be forgotten that the formalities of law, though here and there they may lead to the escape of an offender, are intended on the whole to insure the safe administration of justice and the protection of innocence, and must be observed. A party accused has the right to insist on them as matter of right, of which he cannot be deprived against his will; and the Judge must see that they are followed.
