is claimed of him as payable in point of honor and honesty, although it could not have been recovered from him by any course of law; as in payment of a debt barred by the statute of limitations, or contracted during his infancy, or to the extent of principal and legal interest upon a usurious contract, or, for money fairly lost at play: because in all these cases, the defendant may retain it with a safe conscience, though by positive law he was barred from recovering. But it lies for money paid by mistake; or upon a consideration which happens to fail; or for money got through imposition (express or implied); or extortion; or oppression; or an undue advantage taken of the plaintiff’s situation, contrary to laws made for the protection of persons under those circumstances.

Quoting the above, Mr. Holdsworth in his work on the History of English Law, volume 8, page 97, uses this language: “It was thus in the action of indebitatus assumpsit that the larger part of our modern law of quasi-contract has originated.”

Where one person has wrongfully taken another’s money, or has taken his property and converted it into money, the latter has a right of action ex delicto for the wrong done to him, as by an action of trespass or trover, or by an action on the case for the fraud. He is not always restricted, however, to an action ex delicto for the specific wrong, but may in general waive the tort, and sue in assumpsit for the money as for money received for his use. . . . Where a person steals another’s money or property, or obtains it
