BECK, Judge:

The issue on appeal is whether the trial court erred in granting the plaintiffs' motion to strike the defendant's answer and new matter, where the answer and new matter was filed three years and nine months after the plaintiffs filed their complaint. We find that the trial court did not abuse its broad discretion in granting the plaintiffs' motion to strike and, therefore, affirm that ruling.

Charles Francisco and Cecilia Francisco filed a complaint on October 10, 1985, against Hertz Penske Truck Leasing, Inc. ("Hertz") for injuries which were allegedly caused by an automobile accident which occurred on February 15, 1983. On July 19, 1989, approximately three years and nine months later, Hertz filed an answer and new matter. Thereafter, the plaintiffs filed a motion to strike the answer and new matter, which was granted by the trial court. Hertz then requested the court to reconsider its order granting the plaintiffs' motion to strike. After reconsideration, the trial court again granted the plaintiffs' motion to strike. Hertz appeals this decision.

On appeal, appellant contends that the trial court abused its discretion in striking appellant's answer and new matter. Appellant argues that appellees suffered no prejudice as a result of the late filing of the answer and new matter. In addition, appellant asserts that striking an untimely filed answer and new matter is inappropriate. Rather, appellant contends that the appropriate procedure was for appellees to file for a default judgment. Appellant asserts, therefore, that the trial court lacked the authority to strike the answer and new matter.

We must evaluate appellant's claim of error within the constraints of the abuse of discretion standard. Allison v. Merris, 342 Pa. Super. 571, 574, 493 A.2d 738, 740 (1985); Urban, 332 Pa.Super. at 378, 481 A.2d at 665. Thus, as an appellate court reviewing the ruling of a trial court, we may not substitute our judgment for the judgment of the trial court, absent evidence that the trial court abused its discretion. With this standard in mind we review appellant's claim of error.

Pennsylvania Rule of Civil Procedure 1026 provides that "every pleading subsequent to the complaint shall be filed within twenty days after the service of the preceding pleading. . . ." Pa.R.C.P. 1026 (emphasis added). The word "shall" in Rule 1026 has always been interpreted flexibly, thus permitting exception to the rule where justice so requires. Fisher v. Hill, 368 Pa. 53, 57, 81 A.2d 860, 863 (1951). Thus, the twenty day filing rule is said to be permissive rather than mandatory. Urban, 332 Pa.Super. at 378, 481 A.2d at 665. We cannot emphasize strongly enough, however, that the decision of whether or not to grant an exception to the twenty day filing rule is within the trial court's discretion. A pleading that is not filed within the articulated time period may be stricken by the court. Joyce v. Safeguard Mut. Ins. Co., 362 Pa. Super. 522, 524 A.2d 1362 (1987), rev'd on other grounds sub. nom Safeguard Mut. Ins. Co. v. Joyce, 517 Pa. 488, 539 A.2d 340 (1988) (citing Pa.R.C.P. 1017(b)(2)). As long as the trial court has not abused its discretion, we cannot reverse such a ruling.

Appellant contends that the trial court should have denied appellees' motion to strike, because the correct procedure required appellees to file a motion for a default judgment, rather than a motion to strike. In order to evaluate this contention, we believe it is necessary to describe the development of Pennsylvania case law in this area.

In Paulish v. Bakaitis, 442 Pa. 434, 275 A.2d 318 (1971), the Pennsylvania Supreme Court observed that a pleading may be filed after the expiration of the twenty day period "`if the opposite party is not prejudiced and justice requires. Much must be left to the discretion of the lower court.'" Id., 442 Pa. at 441, 275 A.2d at 322 (quoting Fisher v. Hill, 368 Pa. 53, 81 A.2d 860 (1951) (emphasis added).

Almost fifteen years later this court in Allison supra, relied upon the principle enunciated in Paulish when it considered whether the trial court properly refused to strike the defendant's answer and counterclaim filed approximately two weeks after the expiration of the twenty day filing period. The Allison court articulated the general rule that "the late filing of an answer will be ignored where the plaintiff has not acted to take a judgment by default." Id. 342 Pa.Super. at 574, 493 A.2d at 739. The court based this general rule on the principle that if a party does not take a judgment by default, he or she could not have suffered any prejudice. If a party suffered no prejudice, the Allison court opined, his or her delay in taking a judgment by default would be viewed as impliedly granting an extension of the twenty day filing period. The court concluded, therefore, that because the delay was brief and was promptly cured, the trial court did not abuse its discretion in refusing to strike the answer and counterclaim. Id. 342 Pa.Super. at 574, 493 A.2d at 740.

Several years later this court, in the en banc decision of Joyce, supra, considered whether the trial court correctly denied a party's motion for leave to file a late answer, where five years had elapsed between the service of the original complaint and the defendant's attempt to file an answer eight days prior to an arbitration hearing. Initially, the Joyce court articulated the general rule announced in Allison. The court declared, however, that despite this general rule it would not "excuse the abject indifference . . . reflected by an intervening period of almost five years between the service of the complaint and the effort to file an answer. . . ." Id., 362 Pa. Super. at 526, 524 A.2d at 1363 (emphasis added). The court relied, in part, upon Pennsylvania Rule of Civil Procedure 1003, which provides that where a party seeks to file a late pleading, cause must be shown to explain why the statutory filing period should be extended. Pa.R.C.P. 1003. The court ultimately concluded that because the defendant failed to introduce sufficient evidence to meet the "cause shown" requirement of Rule 1003, the party opposing the late pleading was not required to introduce evidence that it had been prejudiced. The court affirmed the trial court's denial of the defendant's motion to file a late answer. Id., 362 Pa. Super. at 528, 524 A.2d at 1365.

With this case law in mind, we turn now to an evaluation of the trial court's ruling in the instant case. In the case sub judice, appellant filed an answer and new matter three years and nine months after appellees filed their complaint. Appellees objected to this late filing by filing a motion to strike appellant's answer and new matter. The trial court initially granted this motion and, after reconsideration, affirmed this ruling. We find that based upon this court's en banc decision in Joyce, the trial court was wholly within the bounds of its discretion in granting appellees' motion to strike.

We believe that the three year and nine month delay in filing an answer constituted "abject indifference" as recognized in Joyce. The trial court's refusal to ignore this blatant disregard for the time limits delineated in our rules of civil procedure was wholly within the bounds of its discretion based upon the principles enunciated in Joyce and the Pennsylvania Rules of Civil Procedure. We emphasize that while Pennsylvania Rule of Civil Procedure 126 instructs that we "liberally construe[ ]" the Rules, this does not require courts to completely ignore them. We decline to interpret Rule 126 as requiring such a result.

Appellant opposes this resolution on several grounds. Appellant asserts that its answer cannot be stricken because appellees have failed to establish that they have been prejudiced by the late filing. While we agree that the prejudice appellees assert they have suffered is not the type of prejudice required under Rule 1026, we find it unnecessary to reach this stage of the analysis. As this court correctly noted in Joyce:

It is true that had appellant simply filed the answer without permission of the court, appellee would have been required to initiate a motion to strike the pleading. Appellee would have done so, of course, by filing preliminary objections in the nature of a motion to strike. Appellant, had appellee been forced to such an initiative, would have been required to file a response to the petition to strike the late answer and new matter, and presented in that response, as well as at the subsequent evidentiary hearing, the basis for an assertion that there was "cause" why the late pleading should be allowed. Had appellant failed to establish such cause, appellee would have been relieved of the burden of establishing the manner in which she was prejudiced.

Joyce, 362 Pa.Super. at 528-29, 524 A.2d at 1365 (emphasis added). Here, appellant failed to establish the basis for the three year and nine month delay in filing. This being so, we conclude that appellant has failed to meet the cause requirement. Thus, the burden has not shifted to appellees to establish how they were prejudiced by the delay. Appellees failure to do so, therefore, cannot constitute grounds for reversal of the trial court and reinstatement of appellant's answer and new matter.

Appellant also contends that our finding in Allison requires this court to conclude that any time a party fails to seek a default judgment as a result of a late filed pleading, this automatically extends the period within which the party may file its late pleading. Appellant, however, mischaracterizes this court's opinion in Allison. The Allison court held that where a party does not seek a default judgment, it is within the trial court's discretion to find that the period within which to file an answer has been extended. Thus, in Allison the court found that because the plaintiff failed to move for a default judgment, the trial court could, within its discretion, refuse to strike the untimely filed answer. Allison did not, however, establish the inverse principle, i.e., that where a party does not seek a default judgment the trial court will be found to have abused its discretion where it strikes an answer where a party has not first moved for a default judgment.

Allison left intact a trial court's authority to strike an untimely filed answer where justice does not require the twenty day rule to be extended. In the instant case, the trial judge concluded that the appellant's three year and nine month delay in filing its answer and new matter, despite the appellees having not moved for a default judgment, did not warrant an extension of the twenty day filing requirement. It is clear that his decision to do so was wholly within his broad discretion over this issue.

In addition, we emphasize that Allison is clearly factually distinguishable from the case sub judice. In Allison, the defendant delayed filing its answer only two weeks beyond the twenty day period. The Allison court highlighted this minimal delay as one of the primary bases supporting its decision to extend the filing period. Conversely, appellant in the instant case delayed three years and nine months in filing its answer. Undoubtedly, these cases are factually distinguishable. This court's holding in Allison does not conflict with the disposition here enunciated.

The order of the trial court granting appellees' motion to strike appellant's answer and new matter is affirmed. Jurisdiction is relinquished.
