"In Magna Carta it is more than once insisted on as the principal bulwark of our liberties; but especially by chap. 29. that no freeman shall be hurt… - William Blackstone

Of all the parts of a law the most effectual is the vindicatory. For it is but lost labor to say, “do this, or avoid that,” unless we also declare, “this shall be the consequence of your non-compliance.” We must therefore observe, that the main strength and force of a law consists in the penalty annexed to it. Herein is to be found the principal obligation of human laws. Legislators and their laws are said to compel and oblige; not that by any natural violence they so constrain a man, as to render it impossible for him to act otherwise than as they direct, which is the strict sense of obligation: but because, by declaring and exhibiting a penalty against offenders, they bring it to pass that no man can easily choose to transgress the law; since, by reason of the impending correction, compliance is in a high degree preferable to disobedience.

So great moreover is the regard of the law for private property, that it will not authorize the least violation of it; no, not even for the general good of the whole community. If a new road, for instance, were to be made through the grounds of a private person, it might perhaps be extensively beneficial to the public; but the law permits no man, or set of men, to do this without consent of the owner of the land. In vain may it be urged, that the good of the individual ought to yield to that of the community; for it would be dangerous to allow any private man, or even any public tribunal, to be the judge of this common good, and to decide whether it be expedient or no. Besides, the public good is in nothing more essentially interested, than in the protection of every individual's private rights, as modelled by the municipal law. In this, and similar cases the legislature alone can, and indeed frequently does, interpose, and compel the individual to acquiesce. But how does it interpose and compel? Not by absolutely stripping the subject of his property in an arbitrary manner; but by giving him a full indemnification and equivalent for the injury thereby sustained.

Time whereof the memory of man runneth not to the contrary.
