This action in unlawful detainer was instituted by the plaintiff for the purpose of recovering from the defendant the possession of certain real property in the city of Madera. It was alleged that defendant had occupied the premises under a tenancy from month to month; that the tenancy had been terminated and possession of the premises demanded by plaintiff in accordance with the provisions of section 789 of the Civil Code and section 1161 of the Code of Civil Procedure, and that the defendant refused to surrender the premises and was holding the same without plaintiff’s permission or consent. The defendant by his answer denied that the property in suit was occupied under a month to month tenancy, and then, by way of cross-complaint, proceeded to allege a cause of action for specific performance of an alleged partially executed parol agreement. In this behalf the cross-complaint alleged, in substance, that plaintiff and defendant had entered into an oral agreement whereby plaintiff had agreed to execute a written lease to the premises in suit containing certain terms, specifically set forth in the cross-complaint, and that the defendant entered into possession of the premises pursuant to and upon the understanding and belief that the plaintiff would execute the lease agreed upon, but that plaintiff refused to do so. The property was alleged to be community property and plaintiff’s wife was joined as a cross-defendant. The court overruled a general demurrer to the cross-complaint, found against the plaintiff on the issues raised by the pleadings, and rendered judgment for the defendant and cross-complainant, decreeing specific performance by plaintiff of the agreement to execute the lease and appointing a commissioner to perform in the event of plaintiff’s refusal. The appeal is taken upon the judgment-roll alone.
The paramount point presented in support of the appeal is that a cross-complaint of any kind is inadmissible in an *294 action of unlawful detainer. Preliminarily, counsel for defendant interposed an objection to a consideration of the point just stated for the reason that it was first raised upon oral argument when the appeal was heard in the first instance before the district court of appeal. In response to this objection it will suffice to say that ordinarily where a party has neglected to present a point in his brief he may be precluded from insisting that the court consider the point when deciding the case and from asserting that he has been prejudiced should the court refuse to do so. However, we know of no hard-and-fast rule which prohibits the court from considering and deciding points of law which may not have been urged and argued in the briefs originally filed if it appears to the court that an important legal principle is necessarily involved in the newly discovered point and that a proper disposition of the case requires a discussion and decision of that point. But, however that may be, it appears in the instant case that after the oral argument the point in controversy was fully briefed, and we are satisfied that the defendant will in no way be prejudiced by a consideration of the point which we deem to be necessary to a decision.
In
Arnold
v.
Krigbaum,
While the defendant was not entitled to a judgment in the present proceedings decreeing specific performance of the agreement to execute the lease, nevertheless the part performance of such an agreement can be interposed as an equitable defense to the plaintiff’s attempt to wrest from him the possession of the premises by the summary proceedings in unlawful detainer. In the case of
Gray
v.
Maier, etc.,
*296
Cal. 205 [
We conclude, therefore, that the trial court was not authorized in this action of unlawful detainer to' decree specific performance of the agreement to execute a written lease, but that the court had power to examine into the partial performance of the oral agreement to execute the lease as an equitable defense to the attempt at eviction, and that the court having found in favor of the defendant upon this issue, a new trial is unnecessary.
It is ordered, therefore, that that portion of the judgment decreeing specific performance of the agreement to execute *297 the lease be vacated and set aside and that the remainder of the judgment stand affirmed.
