Appellant is owner of premises wherein she resides, parts of which she rents to others. Appellees are tenants of one of the apartments in the building. Suit for possession of this apartment was brought by appellant charging waste and maintenance of a nuisance. Trial was by jury; verdict and judgment were for defendants.
The complaint alleged that injuries to radiators and other acts of waste were committed; that the plaintiff and other .tenants in the building were kept awake by unseemly noises emanating from the apartment occupied by the defendants, and that other disorderly acts were committed by them.
I
The first error assigned is that defendants’ demand for a jury trial was allowed to stand, although not filed on or before the appearance day, as required by the rules of the Municipal Court.1 The summons required defendants to appear on April 14, 1944. Two days earlier defendants filed a motion to dismiss for lack of sufficient title in plaintiff. This motion was heard on the return day of the summons. It was not decided until April 29, when it was overruled. Meanwhile, on April 28, defendants had filed a demand for jury trial. On the following day the court overruled plaintiff’s motion to strike the demand and set the case for jury trial on May 9th.
The right to jury trial is so jealously regarded by our courts that parties may not be deprived of it by a rigid construction of a procedural rule. Rules or statutes limiting the time for filing a demand for jury trial, although mandatory in terms, are not always so regarded. It is the rule in this' and in other-jurisdictions that where the opposing party is not prejudiced, the court, in its discretion, may waive the delay, and its refusal to enforce the time limitation is not reversible error.2 Where, as here, a motion which might result in the dismissal of the suit was pending and heard on the return day, and the demand was filed before the court had decided that motion, the court’s action was plainly both reasonable and proper.

During the opening statement to the jury by defendants’ counsel he charged that the action was not brought in good faith but was motivated by a dispute over an increase in rent in a proceeding before the Administrator of Rent Control.3 Plaintiff’s objection to this statement was overruled. Later her objection to the admission of defendants’ evidence concerning the proceeding before the Rent Administrator was overruled.
No motion for a mistrial followed the objection to counsel’s opening statement and we cannot consider the point on appeal.4 The record shows that plaintiff, in her case in chief, under examination by her own counsel, testified concerning the dispute before the Rent Commissioner. This was the reason assigned by the court for overruling her objection to the evidence. In this we find no error.
Ill
Evidence of defendants’ reputation for peace and good order was admitted, apparently without objection, and this is assigned as error. But plaintiff produced witnesses who testified to her own good reputation for peace and good order, and other testimony that defendants’ reputation was “not so good.” The reputation of the parties for peace and good order was irrelevant, but when litigants voluntarily try immaterial factual issues to the jury, regardless of who was the first offender, neither may complain.
IV
Plaintiff asserts that after the court had sustained her objection to the admission in evidence of a medical report, defendants’ counsel discussed it and disclosed its contents to the jury. There is nothing in the record to support such a charge.
V
Error is assigned to the refusal of the court to grant two of plaintiff’s prayers, and to the failure of the court to instruct “upon the probative value or consideration to be given to evidence tending to show plaintiff’s mala fides.” No request for the latter was made.
We have examined the instructions given by the court, including three prayers submitted by plaintiff. We think they fully and fairly stated the law applicable to the case. They adequately covered all proper subjects for instruction presented in the rejected prayers.
Affirmed.
