Proceeding pro se, Nick Alfred Aguilar, Texas prisoner # 324831, on parole from an enhanced life sentence for possession of heroin, challenges the dismissal of his pro se civil-rights complaint against the State of Texas. In the complaint, he claimed his incarceration (of a heroin addict) violated the Eighth Amendment’s prohibition against cruel and unusual pdnishment because the State acted with deliberate indifference. A dismissal for failure to state a claim is reviewed de novo. E.g., Varela v. Gonzales, 773 F.3d 704, 707 (5th Cir. 2014).

Aguilar’s contention, that the Attorney General of Texas lacked standing to file the motion to dismiss his complaint, fails because, under Texas law, the Texas Attorney General serves as the common legal representative of State agencies. E.g., Sierra Club v. City of San Antonio, 115 F.3d 311, 314 (5th Cir. 1997).

Aguilar neither recognizes nor challenges the district court’s conclusions that his complaint was barred by the Eleventh Amendment and Heck v. Humphrey, 512 U.S. 477, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994). Accordingly, he has abandoned any challenge to those conclusions. E.g., Brinkmann v. Dali. Cnty. Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987). Furthermore, Aguilar’s reliance on Robinson v. California, 370 U.S. 660, 666-67, 82 S.Ct. 1417, 8 L.Ed.2d 758 (1962), is misplaced because he was not convicted under Texas law based on his use of heroin, but because he possessed it.

AFFIRMED.
