Plaintiff-Appellant David Lauer, Texas prisoner # 1069082, filed an interlocutory appeal of the district court’s denial of his motions for a temporary restraining order, preliminary injunction, and protective order. After Lauer filed his interlocutory appeal, the district court dismissed his complaint with prejudice. Lauer argues in this appeal that the district court erred when it denied injunctive relief.

We lack jurisdiction over the denial of an application for a temporary restraining order. See Faulder v. Johnson, 178 F.3d 741, 742 (5th Cir. 1999). As Lauer fails to argue that the district court erred when it denied his motion for a protective order, he has abandoned this issue. See Hughes v. Johnson, 191 F.3d 607, 613-14 (5th Cir. 1999). Thus, the only issue in this appeal is whether the district court erred when it denied Lauer’s motion for a preliminary injunction.

Lauer fails to explain why his interlocutory appeal of the denial of injunctive relief has merit, even though the district court has now dismissed his lawsuit. He thus has not established a substantial likelihood of success on the merits. See Speaks v. Kruse, 445 F.3d 396, 399-400 (5th Cir. 2006). It is unnecessary for us to consider the remaining prerequisites for injunctive relief. See Walgreen Co. v. Hood, 275 F.3d 475, 478 (5th Cir. 2001).

The judgment of the district court is

AFFIRMED.
