Because the district court failed to heed these fundamental principles, we reverse and remand.
I.
Plaintiff-Appellee United States Oil Recovery Potentially Responsible Partiеs Group ("PRP Group") is an association of over 100 entities cooperating with the Environmental Protection Agency to pay the costs associated with cleanup of a superfund site in Pasadena, Texas. As part of this action, PRP Group sued nearly 1,200 parties they believe should be responsible for part of the environmental remediation costs-including appellants here: the Railroad Commission of Texas, the Texas Department of Criminal Justice, the Texas Department of Transportation, the Texas General Land Office, Stephen F. Austin State University, Texas A&M University, Texas Southern University, the University of Houston, the Texas State University System, and the University of Texas System. PRP Group asserts claims under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA),
The state agency and university defendants filed a motion to dismiss in the district court under Federal Rule of Civil Procedure 12(b)(1), contending that they were immune from suit in federal court because of state sovereign immunity. The district court erroneously denied the 12(b)(1) motion under Rule 12(b)(6) without analysis. It subsequently corrected its order to deny the motion under Rule 12(b)(1) -but did so again without analysis. This appeal followed.
II.
"Whether state defendants are entitled to sovereign immunity is a question of law, reviewed de novo on appeal." Moore v. La. Bd. of Elementary & Secondary Educ. ,
State sovereign immunity "bars an individual from suing a state in fedеral court unless the state consents to suit or Congress has clearly and validly abrogated the state's sovereign immunity." Perez v. Region 20 Educ. Serv. Ctr. ,
III.
As the parties agree, CERCLA does not abrogate state sovereign immunity. See Seminole Tribe ,
We have previously held that many of the state agencies at issue in this appeal are entitled to sovereign immunity as arms of the state. See , e.g. , Neinast v. Texas ,
So too for the universities. See , e.g. , United Carolina Bank v. Bd. of Regents of Stephen F. Austin State Univ. ,
Even if this question were not answered by our precedent, we would have little trouble concluding that the agencies and universities at issue here are arms of the state under the test set out in Clark v. Tarrant County ,
PRP Group seeks to avoid this straightforward conclusion with two arguments unsupported by our precedent. First, PRP Group contends that sovereign immunity does not protect an arm of the state when it engages in "proprietary functions," citing Arroyo Otero v. Hernandez Purcell ,
Secоnd, PRP Group contends that the Texas Commission on Environmental Quality has waived sovereign immunity by participating in CERCLA cleanup with the EPA at the Pasadena superfund site. But an arm of the state waives state sovereign immunity only if it "voluntarily invokes federal court jurisdiction, or ... makes a 'clear declaration' that it intends to submit itself to federal court jurisdiction."
In sum, we conclude that the agencies and universities are entitled to state sovereign immunity. PRP Group's arguments to the contrary are unavailing. The district court erred when it concluded that state sovereign immunity did not bar PRP Group's CERCLA claims.
IV.
We likewise reverse as to PRP Group's state law claims. PRP Group contends that, because the TSWDA waives Texas's sovereign immunity in Texаs state court, the federal district court could properly exercise supplemental jurisdiction over these claims. Yet a district court may only exercise supplemental jurisdiction over pendent state law claims under
Because the district court erred when it concluded that state sovereign immunity did not bar PRP Group's claims against the agencies and universities, the district court lacked jurisdiction in the first instance. Therefore, it cannot assert supplemental jurisdiction over PRP Group's state law claims.
V.
The district court's order denying the agencies and universities' Rule 12(b)(1) motion to dismiss is reversed. The case is remanded with instructions for the district court to dismiss the agencies and universities from the case.
Notes
PRP Group seeks to take the agencies and universities to task for failing to cite Clark in the district court, and contends that failure means they cannot argue that Clark is satisfied here. Not so. Before the district court, PRP Group expressly declined to contest that the agencies and universities here were arms of the state. Rather, PRP Grоup "assumed" they were arms of the state. And the agencies and universities asserted their state sovereign immunity defense in the district court from the outset. The agencies and universities have not waived this argument, nor are they precluded from citing state statutes and cases to support it.
