(After stating the facts as above.) The -question thus presented is this: A plaintiff by oath-brings his case within the jurisdiction of a Justice under the Landlord and Tenant Act, (Bat. Rev. ch.- 64 § 19,) and the defendant by answer denies the tenancy and alleges a title in himself. Shall the Justice proceed to inquire whether the • defendant did enter as tenant of the plaintiff and whether his term has expired, or shall he upon the answer merely, dismiss the proceedings. ' .
We are not aware that this precise question has been heretofore decided, although expressions bearing on it more or less directly may be found in several cases;
Forsythe
v.
Bullock,
It is a necessary function of every Court to pass in the first instance on its own jurisdiction, and if the jurisdiction depends on a fact, it must necessarily determine the existence of the fact. Many examples might be given where it is evident that any other practice would be absurd. A case affecting an ambassador can be tried only in the Supreme Court of the United States ;'but if every defendant in any other Court can dismiss the action by alleging that he is an ambassador, it would appear that foreign Courts were represented in this country to .an alarming extent. A Probate Judge has no jurisdiction to grant administration except on the estate of a person deceased, and in every case he tries and determines the'fact of death. Pleas to the jurisdiction! must be pleaded and determined before any other plea can be put in Chit. PL In the present case, the plea is a denial of the tenancy and the plaintiff must prove his allegation and the Justice must decide on it upon the evidence. If he-finds that the defendant was a tenant he must proceed to try any other matters in issue and -give such judgment as may be proper. No claim of a freehold title in the defendant can. be allowed to be made. It is impertinent; for if the defendant is not a tenant, it is immaterial, as on the failure-of proof that he is, the jurisdiction fails; and if he is á tenant, the plea of title cannót avail him as he is estopped to-allege it.
The Judge of the Superior Court properly refused to dis*miss the proceedings. Pie should have proceeded to try the case and to give such judgment as the Justice might and ought to have given. It is by no means admitted that the defendant could appeal from the refusal of the Judge to dismiss the action. It does not appear to have affected any *164 substantial right of the defendant, and appeals from interlocutory judgments are not to be favored beyond the letter-of the law, as they unnecessarily and uselessly lengthen litigation.
Judgment below affirmed. Case remanded. Let this (opinion be certified.
.Pee, Curiam. Judgment affirmed.
