This is аn appeal from an order granting the Defendants’ motion to dismiss the Plaintiffs’ claims on the basis of forum non conveniens. For the reasons set forth below, we vacate the order and remand the case to the district court.
I.
The underlying litigation in this appeal arises out of a single vehicle accident that оccurred on June 26, 2001, on a Mexican national highway in Camino Tijuana/Cabo San Lucas, Mexico. Plaintiffs, all of whom *652 are Mexican nationals, allege that the General Motors vehicle in which they traveled as well as a Cooper Tire & Rubber Company tire on the vehicle, were defective and contributed to the accident. The Plaintiffs have also named Vincente Dominguez-Mendoza, their family member and the driver of the vehicle, as a defendant in the undеrlying action, alleging negligence and that he was thus at least partially responsible for causing the accident: The district court dismissed the action based on forum non conveniens.
II.
In granting the Defendants’ motion, the district court reached the forum non con-veniens issue before deciding whether it had subject matter jurisdiction over the controversy. It is a settled principle that, “before proceeding with a case, federal trial and appellate cоurts have the duty to examine the basis for their subject matter jurisdiction, doing so on their own motion if necessary”.
Torres v. Southern Peru Copper Corp.,
In
Ruhrgas,
the Supreme Court held only that, while Article III “requires a federal court to satisfy itself of its jurisdiction over the subject matter before it considers the merits of a case”,
Ruhrgas,
Thus, we hold that the district court erred in dismissing the case on forum non conveniens grounds without first determining whether it had subject matter jurisdiction.
In sо holding, we disagree with other Circuits that have addressed this issue, namely the 2nd Circuit and the DC Circuit.
See In the Matter of Arbitration between Monegasque De Reassuranсes S.A.M. v. Nak Naftogaz of Ukraine,
*653 Thus, although subject-mattеr jurisdiction is special for many purposes (e.g., the duty of courts to bring it up on their own), a court that dismisses on other non-merits grounds such as forum non conveniens and personal jurisdiction, makes no assumption of law declaring power that violates the separation of power principles underlying Mansfield and Steel Company.
Papandreou,
Before the Supreme Court decided
Steel Co. v. Citizens for a Better Environment,
Appellants urge an expansive reading of
Ruhrgas,
arguing that the Supreme Court authorized a court to pretermit a ruling on jurisdiction and decide the case on any “non-merits” issue. They then characterize forum non conveniens as a non-mеrits issue. As stated above, we do not read
Ruhrgas
broadly enough to allow us to pretermit a decision on jurisdiction before deciding some other “non-merits” issue. Even, however, if we could read
Ruhrgas
that broadly, we are satisfied, based on our precedent, that “the question of the convenience of the forum is not ‘completely separate from the merits of the action.’ ”
Van Cauwenberghe v. Biard,
The forum non conveniens inquiry consists of several steps.
First, the defendant invoking the doctrine must establish that an alternate forum is both available and аdequate. An available forum is one ivhere the case and all the parties can come within its ju/risdiction ...
Having established an available and adequate forum, the defendant must then show that certain private factors support dismissal. These private factors are: (1) the relative ease of access to sources of proof; (2) the availability of compulsory process for attendance of unwilling, and the costs of obtaining attendance of willing, witnesses; (3) probability of an opportunity to view the premises, if view would be appropriate to the action; and (4) other factors affecting the ease, speed, and expense of trial or the enforceability of a judgment if obtained.
If these private interest factors do not indicatе that another forum is better suited for trial of the case, the court should then examine certain public interest factors ... The public interest factors аre: 'The administrative difñcul *654 ties flowing from court congestion, the “local interest in having localized controversies decided at home”; the interest in having the trial of a diversity case in a forum that is at home with the law that must govern the action; the avoidance of unnecessary problems in conflict of laws, оr in the application of foreign law; and the unfairness of burdening citizens in an unrelated forum with jury duty.
Brokerwood Products International, Inc. v. Cuisine Crotone, Inc.,
For the above reasons, we vacate the district court’s order and remand the case to the district court to determine whether it has subject matter jurisdiction over this controversy.
VACATED and REMANDED.
