The complaint in this case is more nearly a complaint in ejectment than upon any other cause of action, but, as such a complaint, the municipal court had no jurisdiction to try it. If, by very liberal interpretation, it may be regarded as a complaint under chapter 84, ríen. St. 1878, it can only be under section 2 of that chapter, and that by reason of the allegation that the premises are unlawfully and forcibly detained. There is no suggestion in it of any sale on execution, judgment, or foreclosure by advertisement, or of any of the other cases specified in section 11. As a proceeding under section 2, the evidence wholly failed, for there was nothing in it tending to show a forcible detention. Evidence of the foreclosure proceedings was inadmissible to make a case under section 11, because the complaint did not allege such foreclosure; and had the complaint been such as to admit proof of a holding over after foreclosure by advertisement and expiration of the time for redemption, the evidence that was offered, the notice of sale, affidavits of publication and of sale, and certificate of sale, were inadmissible without proof of a mortgage authorizing the sale, and no proof of such was given or proposed to be given.

The objection to the introduction of the certificate of sale ought to have been sustained, both because not justified by the complaint, and because no foundation, by introducing the mortgage, was laid. Laws 1883, c. 112, does not dispense with proof of the mortgage where title is to be made under a mortgage, and foreclosure pursuant to the power in it, nor make the certificate a substitute for such proof. The certificate is of no effect until it appears that the sale was made *78under a power to sell “contained in a mortgage.” The recitals in it ■do not prove the power nor mortgage; the most that they can prove is compliance with the requirements of law in “that behalf,” i. e., in the sale proceedings.

Judgment reversed.
