Appellant, Dorothy Osei-Kuffnor, appeals from the grant of judgment under
I
Appellant filed a complaint in the Superi- or Court of the District of Columbia against appellee Maria Argana on February 11,1991. Appellee answered on February 21, 1991, and filed a motion for judgment on the pleadings under Super.Ct.Civ.R. 12(c) on August 9, 1991, on the grounds of res judicata.
Appellee’s motion stated that appellant’s personal injury action had been adjudicated in the District Court of Maryland for Prince Georges County. Attached to appel-lee’s memorandum of points and authorities was a certified copy of a judgment entered by the Maryland Court. The judgment listed appellant as plaintiff and appel-lee and Maryland Automobile Insurance Fund as defendants in a small claims complaint filed on February 2, 1990.

It also showed that following a trial before Judge Nolan on April 26, 1990, judgment was entered in favor of appellee. Relying on
Goldkind v. Snider Bros., Inc.,
In-opposition to the motion, appellant argued that appellee had failed to provide any substantiation for the allegation that the Maryland lawsuit evolved from the same set of facts as those in the instant case, and that appellee had failed to raise the
res judicata
defense in her answer. In her memorandum of points and authorities appellant noted that the judgment attached to appellee’s memorandum did not reflect the date of the accident or the cause and circumstances of the claim made by the plaintiff against the defendant, and hence, the motions judge could not make any finding as to the nature of the lawsuit filed in the Maryland District Court. She relied on
Abramson v. Grady,
II
On appeal appellant contends that the motions judge erred in granting appellee’s motion for judgment on the pleadings on res judicata grounds. She maintains that appellee failed to prove that the Maryland and District of Columbia lawsuits are the same because the copy of the judgment did not describe the cause of action in the Maryland case.

This court has held that our review of the grant of judgment for failure to state a cause of action under Super.Ct.Civ.R. 12(b)(6) is
de novo. Johnson-El v. District of Columbia,
A trial court may take judicial notice of a prior case between the two parties “if it can be determined that the cases are essentially the same.”
Abramson v. Grady, supra,
In contrast to Abramson v. Grady, there is a transcript of the proceedings in the trial court which clearly reveals that there are no material disputed facts in the instant case. Appellee asserted in her pleadings and in argument before the motions judge that the Maryland and District of Columbia lawsuits were the same, and attached a certified copy of a court judgment to her pleading in support of her assertion. Appellant has never contested that there was a prior lawsuit between herself and appellee or that the certified copy of the judgment did not refer to such a suit. Nor has she claimed that the Maryland lawsuit did not arise out of the same accident or proffer any document, by affidavit or otherwise, to show that the two lawsuits were not the same. Even at oral argument she did not suggest to the motions judge what the Maryland lawsuit involved and why it differed from the instant lawsuit; nor did she offer a copy of a pleading from the Maryland lawsuit to show that the two suits were different. Instead, she asserted only that appellee had failed to show that the facts and occurrence at issue in the two cases was the same.
Even if appellee’s motion is properly viewed as one for summary judgment,
see Launay v. Launay Inc.,
Under these circumstances, the motions judge could properly conclude that because the two lawsuits were essentially the same, and because appellant’s other contentions were unpersuasive, the instant lawsuit is barred by res judicata.
Appellant’s contention that appellee waived the affirmative defense of
res judi-cata
because she did not plead it in her answer fails. Her reliance on
Flippo Construction v. Mike Park’s Diving Corp., supra,
Appellant’s other contention, that
res judicata
does not apply because the amount of damages that she seeks in the instant case is substantially greater than she could have recovered in the Maryland lawsuit as a result of the jurisdictional limit of the Prince Georges County District Court, is also unpersuasive.
Res judicata
is based on the premises that “the aggrieved party should be given but one opportunity to allege that wrong ... [and] where the facts that give rise to a legal action are fully litigated in one forum, there is no rationale for relitigating those facts elsewhere.”
Henderson v. Snider Bros., Inc.,
Accordingly, we affirm the judgment.
Notes
. The judgment indicated that Maryland Automobile Insurance Fund was dismissed as a party defendant on March 28, 1990.
. Appellant contends that she was prejudiced because her lawyer did not know about the Maryland case. This court cannot imagine why ■it is the defense’s responsibility to fill in gaps a plaintiff chooses not to tell her own lawyer. The trial judge was of the same opinion.
