These are cross-appeals from a final judgment following an order granting a new trial in a personal injury action. Plaintiff seeks to reinstate a $65,000 jury verdict in her favor. Defendant has cross-appealed. 1 We conclude that the trial court abused its discretion in granting a new trial. Hence, we remand for reinstatement of the jury verdict.
On April 9,1979, the plaintiff, Mrs. Patricia A. Bell, suffered injuries when her foot suddenly became caught in Escalator Number Five at the Eastern Market Metrorail Station, сausing her to fall. Escalator Number Five was manufactured by Westinghouse Electric Corporation (“Westinghouse”), which purportedly maintained the apparatus pursuant to a service contract with Washington Metropolitan Area Transit Authоrity (“WMATA”). On November 9, 1979, plaintiff commenced a civil action (No. 14410-79) against both WMATA and Westinghouse seeking to hold both defendants jointly and severally liable for the injuries she sustained in the escalator incident. WMATA filed an answer to the complaint and a сross-claim against Westinghouse; Westinghouse also answered but never filed any cross-claim against WMA-TA. On December 2, 1981, the initial date set for trial, WMATA moved to dismiss the complaint against it for lack of jurisdiction. Westinghouse did not oppose this motion. The court granted WMATA’s motion on the ground that the United States District Court for the District of Columbia had exclusive jurisdiction over actions brought against WMATA. On January 25, 1983, trial commenced on plaintiff’s personal injury claim against Westinghouse as sole defendant. Westinghouse interposed no objection to the action commencing solely against it.
On January 26, 1983, this court rendered its decision in
Qasim v. Washington Metropolitan Area Transit Authority,
After trial, Westinghouse filed a timely mоtion seeking, in the alternative, a judgment n.o.v., a new trial, or a remittitur. Among other things, Westinghouse argued that a new trial was appropriate because it had been “prejudiced” by the absence of WMATA at trial. The trial court agreed and grаnted a new trial. The court did this before plaintiff had had an opportunity to oppose the motion. After plaintiff moved for reconsideration of the trial court’s ruling, the court entered an order reaffirming its earlier grant of a new trial. Since plaintiff took no steps to have WMATA reinstated as a defendant, and since Westinghouse did not file a third-party complaint against WMATA, the action proceeded to a second trial against Westinghouse alone. At the second trial, Mrs. Bell put on minimal evidence and a directed verdict resulted against her. These cross-appeals followed.
On appeal, Mrs. Bell seeks reversal of the order granting a new trial and reinstatement of the jury verdict. She asserts that Wеstinghouse was not prejudiced by the dismissal of WMATA before trial be *327 cause WMATA was not an indispensable party. Westinghouse claims that it was prejudiced so as to justify a new trial. It also asserts that the trial court should have granted a new trial becаuse the jury had been improperly instructed on the doctrine of res ipsa loquitur.
I
Super.Ct.Civ.lt. 59 broadly sets forth the criteria for granting a new trial:
(a) GROUNDS. A new trial may be granted to all or any of the parties and on all or part of the issues (1) in an action in which there has been a trial by jury, for any of the reasons for which new trials have heretofore been granted in actions at law in the courts of the United States or of the District of Columbia ....
New trials may be granted, for example, where the verdict is against the weight of the evidence, damages are excessive, the trial was unfair, or there was a prejudicial legal error in the proceedings.
Baber v. Buckley,
It is generally held that a trial сourt has the power to order a new trial when such action is needed to “prevent injustice.” 11 Wright & Miller,
supra,
§ 2805, at 38. The granting of such a motion is within the discretion of the trial court and the scope of appellate review is limited to determining whether thеre has been an abuse of discretion.
2
Baber v. Buckley, supra,
A.
Westinghouse asserted in its motion for a new trial, and continues to assert on appeal, that it was prejudiced by WMA-TA’s dismissal, as that dismissal relates to plaintiffs use of the doctrine of res ipsa loquitur.
3
Westinghouse and WMATA were alleged to be joint tortfeasors. Westinghouse argues that had WMATA been a party to the first trial the jury could have considerеd the respective liabilities of both WMATA and Westinghouse under the res ipsa loquitur doctrine. Joint tortfeasors, however, are precluded from using res ipsa loquitur against each other, as a basis for indemnification or contribution.
Washington Sheraton Corp. v. Keeter,
Indeed, this approach would preclude a plaintiff in a negligence action, where more than one tortfeasor is allegedly involved, from using the res ipsa loquitur doctrine
*328
unless all tortfeasors were joined in the litigation. We have never held that use of the doctrine should be limited in this way.
Cf. Washington Sheraton Corp. v. Keeter, supra,
Westinghouse’s subtantive right of indemnification or contribution has in no way been affected by Mrs. Bell’s jury verdict.
See Hall v. General Motors Corp.,
B.
Secondly, Westinghouse moved for a new trial on a general assertion of prejudice. To dаte, Westinghouse implies but has never directly asserted that WMATA was an indispensable party, under Super.Ct.Civ.R. 19(a),
5
at the first trial.
6
If WMATA had been an indispensable party, its improper dismissal from the case before trial would constitute the kind of prejudicial legal errоr that would justify granting Westinghouse a new trial. It is an established rule, however, that joint tortfeasors are not indispensable parties.
See
Super.Ct.Civ.R. 19(a);
Stabilisierungsfonds Fur Wein v. Kaiser Stuhl Wine Distributors Pty. Ltd.,
A party is prejudiced at trial when a legal ruling adversely affects its legal rights. Since WMATA was not an indispensable party, Westinghouse had no right to have WMATA joined as a defendant. Accordingly, WMATA’s dismissal from the case 7 was not an error which prejudiced Westinghouse.
We observe that in its order the trial court stated:
[T]he inconvenience and expense of a new trial is outweighed by the prejudice suffered by the defendant Westinghouse through the initial dismissal of WMATA as a party, and the eventual single defendant trial.
This balancing was inadequate since the trial court neglected to also weigh the plaintiff’s very significant interest in not having her jury verdict set aside. Moreover, as previously stated, Westinghouse was not prejudiced by WMATA’s dismissal. In sum, we find the court did not exercise *329 sound discretion in granting the motion for a new trial.
II
Alternatively, 8 Westinghouse argues that the evidence adduced at trial did not warrant submission of the negligence issue to the jury on the theory of res ipsa loquitur. 9 We disagree.
The conditions which must be satisfied for the application оf the doctrine of res ipsa loquitur are as follows:
(1) The event must be of the kind which ordinarily does not occur in the absence of someone’s negligence; (2) it must be caused by an agency or instrumentality within the exclusive control of the defеndant; (3) it must not have been due to any voluntary action or contribution on the part of the plaintiff.
Prosser, Law of Torts § 39, at 214 (4th ed. 1971), cited with approval in
Sullivan v. Snyder,
In the instant case the escalator was manufactured and installed by Westinghouse, which purportedly maintained it pursuant to a contract with WMATA. The fact that WMATA and Westinghouse exercisеd joint control over the escalator does not preclude the application of res ipsa loquitur. Id.
Mrs. Bell testified that she got on the escalator and rode three quarters of the way down when she suddently felt something “tugging” at her shoе. When she tried to pull the heel of her shoe free, the heel broke off causing her to fall the rest of the way down the escalator. Plaintiff offered into evidence at trial the heel of her sandal which showed damage from its being grasрed by the escalator treads. These facts support an instruction on res ipsa loquitur. In
Levy v. D. C. Transit System, Inc.,
Finding no basis for Westinghouse’s assertions of prejudice, we conclude that the trial court abused its discretion in granting a new trial. Accordingly, we reverse and remand for reinstatement of the jury’s verdict.
So ordered.
Notes
. Upon scrutiny of the record we find no final adverse order from which Westinghouse has a right of appeal. Therefore, we dismiss its cross-appeal.
.We observe that different considerations apply in our review of the granting of a new trial than where such a motion has been denied. While the scope of our review is still limited, we have a greater duty here, where the trial court has to a certain extent substitutеd its judgment for that of the jury.
Taylor v. Washington Terminal Co.,
. For our discussion of whether plaintiff should have been allowed to use the res ipsa loquitur doctrine, see Part II, infra.
. It is particularly inappropriate that Westinghouse raises this argument since it took no steps to cross-claim against WMATA or implead WMATA as a third party defendant.
. Super.Ct.Civ.R. 19(a) is identical to Fed.R.Civ.P. 19 except for the deletion of the last sentence in section (a) relating to venue.
. An objection on grounds of failure to join an indispensable party should be mаde at trial. However, the fact it was not raised at trial does not preclude our review of the issue.
York Blouse Corp. v. Kaplowitz Bros.,
.We do not discuss what effect, if any, this court’s ruling in Qasim v. Washington Metropolitan Area Transit Authority, supra, had on the trial court’s dismissal of WMATA from this casе prior to our ruling.
. Westinghouse raises a variety of claims to support its request for a new trial. We find none of these claims sufficient grounds to warrant the relief that Westinghouse seeks. In particular, Westinghouse claims that the trial court erred in instruсting the jury on a negligence theory of failure to warn. We conclude that the evidence adduced at trial was sufficient to allow submission of a failure to warn theory to the jury.
See Hecht Co. v. Jacobsen,
. We note the inconsistency between this argument and Westinghouse's previous assertion that it was prejudiced because it could not utilize the res ipsa loquitur doctrine against WMA-TA.
