In re Volkswagen Clean Diesel Litigation:

Texas Clean Air Act Enforcement Cases

ORIGINAL PROCEEDING FROM TRAVIS COUNTY

O P I N I O N

The State seeks mandamus relief from the MDL pre-trial court’s refusal to abate

eighteen later-filed cases involving the State’s and various counties’ enforcement of the Texas Clean

Air Act against Volkswagen. The principal issue in this mandamus proceeding—one of first

1

impression—is whether, under this unique factual and procedural posture, the common-law doctrine

of dominant jurisdiction requires that the counties’ later-filed enforcement suits, pending in the

MDL, be abated until resolution of the State’s enforcement suit. Becausewe conclude that theymust

be abated, as explained below, we will conditionally grant the State’s petition for writ of mandamus.

Invoking the doctrine of dominant jurisdiction, the State asserts that it is entitled to

mandamus relief ordering the pretrial court to abate the later-filing counties’ suits because the State’s

The State included this request for mandamus relief in In re Volkswagen Clean Diesel 1

Litigation: Texas Clean Air Act Enforcement Cases, our cause number 03-16-000718-CV. On our

own motion, we severed the State’s petition for writ of mandamus into a separate cause, No. 03-17-

000478-CV. The facts and statutory scheme relevant to this original proceeding are the same as

those set forth in our opinion issued today in In re Volkswagen Clean Diesel Litig.: Tex. Clean Air

Act Enf’t Cases, No. 03-16-000718-CV (Tex. App.—Austin July 28, 2017, no pet. h.).
enforcement suit against Volkswagen was filed before the later-filing counties’ enforcement suits

against Volkswagen. We agree. “In instances where inherently interrelated suits are pending in two

counties, and venue is proper in either county, the court in which suit was first filed acquires

dominant jurisdiction. In these circumstances, the general rule is that the court in the second action

must abate the suit.” If the trial court in the second action—here, the MDL pretrial court acting, as 2

it were, on behalf of the courts in which the later-filing counties brought suit—abuses its discretion

by not abating the action, no additional showing is required for mandamus relief.3

There is no dispute that the State’s TCAA-enforcement action against Volkswagen

was filed first, that venue is proper in each of the counties where the respective cases were filed, 4 5

or that the lawsuits are inherently interrelated. Nor do the later-filing counties suggest that any 6

exceptions to dominant jurisdiction apply here. Instead, the later-filing counties argue that the 7

pretrial court did not abuse its discretion by denying abatement here because the statutory MDL

scheme has somehow displaced the common-law doctrine of dominant jurisdiction. While this

argument may be up for debate in a situation where the dominant-jurisdiction issue arises in

connection with more typical MDL cases—i.e., cases where claimants seek recovery of their own

separate and individual injuries—in the unique circumstance of the statutory enforcement claims

asserted here, we hold that the doctrine of dominant jurisdiction controls. 

“‘[S]tatutes can modify common law rules, but before we construe one to do so, we

must look carefully to be sure that was what the Legislature intended.’” In the MDL statute, the 8

Legislature created a system where civil cases that “involv[e] one or more common questions of

fact” can be transferred to a pretrial court for “consolidated or coordinated pretrial proceedings” if

the transfer will “be for the convenience of the parties and witnesses” and “promote the just and

efficient conduct of the actions.” The MDL process is a statutory tool of economy intended to 9

coordinate or consolidate the pretrial proceedings in pending cases that share underlying questions

of fact, but where the claimants each seek recovery for their own injuries and where, ultimately, the

individual cases will be remanded for separate trials. The doctrine of dominant jurisdiction, by

contrast, applies where cases are inherentlyinterrelated because they“involv[e]the same parties and

the same controversy,” and requires that the later-filed cases “be dismissed if a party to that suit calls

the second court’s attention to the pendency of the prior suit by a plea in abatement.” “The 10

jurisprudential reason for the [dominant-jurisdiction] rule is that once a matter is before a court of

competent jurisdiction, ‘its action must necessarily be exclusive’ because it is ‘impossible that two

courts can, at the same time, possess the power to make a final determination of the same

controversy between the same parties.’” Given the unique circumstances we have before us—i.e., 11

where the State’s and respective counties’ cases all seek to enforce the same environmental

laws by imposing penalties on the same parties for the same violations—we cannot say that the

Legislature intended for the MDL statute to modify or create an exception to the common-law rule

of dominant jurisdiction.12

The later-filing counties argue that, even if dominant jurisdiction attaches to the

State’s case, the abatement issue can be revisited if necessary when the civil-penalty actions are

remanded for their respective trials and, relatedly, that mandamus review is unwarranted here

because neither the State nor the legal system will suffer any harm if the later-filing counties are

allowed to participate in the coordinated pretrial proceedings in the MDLcourt. Because the pretrial

court’s orders are binding in the trial court after remand, however, this “revisiting” could only

happen if the pretrial court decided to rehear an issue it had already decided. But even assuming 13

that this could or would happen, the Texas Supreme Court has declared that once a relator has

established that the doctrine of dominant jurisdiction applies—i.e., the relator’s suit was filed first

in an appropriate venue, remains pending, and is inherently interrelated to the later-filed suit —the 14

trial court in the later-filed case must abate the later-filed case and abuses its discretion in failing to

do so. Further, the supreme court’s decision in J.B. Hunt suggests that we may not delay here,

15

whetherto allow the dominant-jurisdiction issue to “ripen” or because the pretrial court could revisit

the issue before remand. In J.B. Hunt, the supreme court overturned its prior decision holding that

mandamusreliefwas not available unless the second-filed court “activelyinterferes with the exercise

of jurisdiction” in the other court. Instead, the supreme court held that regardless of whether the 16

second court is actively interfering with the dominant court, “a relator need only establish a trial

court’s abuse of discretion to demonstrate entitlement to mandamus relief with regard to a plea in

abatement in a dominant-jurisdiction case.”17

Several of the later-filing counties argue that the doctrine of dominant jurisdiction

does not apply to their respective suits because their lawsuits were the first to include certain

jurisdiction, the [second-filed] court should have granted [relator]’s plea in abatement and abused

its discretion in failing to do so, and [relator] is entitled to mandamus relief.”).

See J.B. Hunt, 492 S.W.3d at 298 (“Abor held that mandamus relief is unavailable to 16

is, there was no injunction or order in one court ‘which actively interferes with the exercise of

jurisdiction’ in the other court.” (quoting Abor v. Black, 695 S.W.2d 564 (Tex. 1985)).

defendants that were not named in the State’s enforcement suits and, thus, that their cases should 18

be considered the first-filed cases against the defendants not named in the State’s enforcement

action. But the supreme court has rejected this argument, explaining that “[i]t is not required that the

exact issues and all the parties be included in the first action before the second is filed, provided that

the claim in the first suit may be amended to bring in all necessary and proper parties and issues.19

Here, nothing prevents the State from adding additional defendants to its enforcement action.

Finally, we note that our decision here is not an assault on the MDL scheme, but

rather is limited to the unique nature and procedural posture of the cases before us. Although fairly

characterized as falling within the MDL statute’s broad scope of sharing common questions of fact,

the cases here are also inherently interrelated, and thus subject to the dominant-jurisdiction doctrine,

because the later-filed suits all seek to recover civil penalties from the same TCAA violators for the

same TCAA violations as does the State’s case. Put anotherway, these TCAA enforcement actions 20

differ from the typical MDL cases in that each local-government action seeks, by definition, to

See id. (“In determining whether an inherent interrelationship exists, courts should be 20

guided by the rule governing persons to be joined if feasible and the compulsory counterclaim rule.”

(citing Tex. R. Civ. P. 39, 97(a)). The cases here meet both rules because, as explained, the counties’

claims are, with the exception of the geographic restriction, identical to the State’s claims and

because the TCAA makes TCEQ (i.e., the State) a necessary and indispensable part to all localgovernment suits. See Tex. Water Code § 7.353 (“In a suit brought by a local government under this

subchapter, the commission is a necessary and indispensable party.”).

punish the very same violations that the State could, using the same penalty and enforcement

mechanism set forth in the TCAA and including the State as a necessary party as required by

the TCAA.

In sum, the Travis County District Court acquired dominant jurisdiction over TCAA

violations in 252 Texas counties, including the county parties here, when the State filed its

enforcement action in that court. The courts in which the later-filed cases were filed—and now the

MDL pretrial court in their stead—should have granted the State’s plea in abatement and abated the

later-filed cases until the State’s first-filed case is resolved. The MDL pretrial court abused its

discretion in failing to do so. 

21

Accordingly, we conditionally grant mandamus relief and direct the pretrial court to

grant the State’s pleas in abatement as to the later-filing counties. We are confident the pretrial court

will promptly comply, and our writ will issue only if it does not.
