(607) but if he will stand by his law, we cannot A policy without any real interest to suphinder it, seeing it is a method the law allows. And the defendant was set at the right corner of the bar, without the bar, and the secondary asked him, if he was ready to wage his law; he answered 'Yes.' Then he laid his hand upon the book, and then the plaintiff was called; and a question thereupon arose whether the plaintiff was demandable. [The court held that he was.] Then the court admonished him [the defendant,] and also his compurgators, which they regarded not so much as to desist from it. Accordingly the defendant was sworn, that he owed not the money modo et forma, as the plaintiff had declared, nor any penny thereof. Then his compurgators standing behind him were called over, and each held up his right hand, and then laid their hands upon the book, and swore that they believed what the defendant swore was true." This formality of acquitting one's self of a claim by oath, was properly and technically called "making law" or "perfecting law;" the word "law" being used in its ancient sense of oath. See Law. Lord Coke, however, supposes the term to mean, "taking the benefit which the law allowed the party." Co. Litt. 295. Wager of law strictly signified merely the preliminary formality of giving gage or security, but (probably in consequence of the ambiguous character of the expression, "making law") is generally used in the books, to denote the whole proceeding. 3 Bl. Com. 341-348. See Fleta, lib. 2, c. 47, § 5. Wager of law was one of the most ancient proceedings in English practice. It is distinctly described in Glanville, (ub. sup.) and was probably introduced by the Saxons. Montesquieu mentions it, under the name of the custom of negative proofs, 3 Kent's port it; a policy in which the insured has no interest, being in fact nothing more than a wager or bet between the parties, whether such a voyage would be performed, or such a ship arrive safe.* Com. 277, 278. A mere hope or expectation, without some interest in the subject matter, is a wager policy. Id. 275. Mr. Arnould defines a wager policy to be " one in which the parties, by express terms, disclaim, on the face of it, the intention of making a contract of indemnity." 1 Arn. on Ins. 276, (281, Perkins' ed.) Policies of this kind are now generally held to be illegal. Id. 285, (289.) 1 Duer on Ins. 93-95. Id. 154, 155.
