{after stating the facts). I think it clear that this bond was not required by the statute. The contract with the Michigan Stone & Supply Co. to furnish limestone dust at the municipal asphalt plant did not make that company a contractor for the building, repairing or ornamenting of “public buildings, other public works or improvements.” If it did, one who furnished a single load of sand or who performed any service about the municipal plant would be equally a contractor. The consequence of holding persons furnishing such material or labor to be contractors would be quite disastrous. It would impose upon municipal authorities the duty of requiring bonds in all such cases, thus unnecessarily hampering the conduct of public business and placing upon public officials unlooked for and burdensome obligations. I think, however, that the facts averred in the declaration make a case on common-law principles. Appellants voluntarily executed the bond. They therein stated that the contract of their principal was within the provisions of the statute under consideration. It is made evident by this recital and by the language of the bond that they intended to take upon themselves the obligation which that statute imposed upon sureties. In other words, it was their intention to thereby become sureties for the payment of material furnished their principal to enable it to perform its contract. By giving this bond as a statutory bond it is to be presumed that appellants intended it “should be deposited with and held” by the officers exacting it “for the use of any party interested therein.” That is, that it was to be held for the use of Henry Houghten and others like him and placed where they could examine it. This was equivalent to a proposal to Houghten to guarantee
“ Even if the -statute, sections 10743 to 10745, 3 Comp. Laws, inclusive — does not require the giving of this bond, we, the parties hereto, take upon ourselves the same obligation as if it were required.”
Any doubt respecting the binding force of such an obligation in ,a contract must rest upon the ground that common-law principles forbid its being entered into. Certainly that ground is untenable, for, according to those principles, appellants could have guaranteed the account of Houghten, and that, under the principles of this opinion, is precisely what they did. This same result would be reached by saying that appellants are estopped from denying that the statute applies to their case. I shrink from making such a statement. It would involve a consideration of the difficult question (see Bigelow on Estoppel [4th Ed.], p. 554), Can one be estopped by a statement of a proposition of law ? And if that question is answered in
Appellants also contend that the bond “ cannot be made effective as a common-law bond ” as in that case ‘ ‘ a suit in the name of the people would not lie.” While this suit is brought in the name of “ The People of the State of Michigan,” the real plaintiff is Henry Houghten, for whose use and benefit the suit is brought. The contention under consideration is, then, merely technical. It should have been raised by demurrer. It was not, and therefore should not now be considered.
If these views are correct, the order of the trial court overruling defendants’ demurrer should be affirmed.
