The Fifth Circuit Court has upheld a $14 million fine against ExxonMobil for air pollution violations in southeast Texas. The court's decision, delivered in a 170-page en banc ruling, included a per curiam opinion indicating that the court would not have reheard the case had it known the opinion would take over 18 months to finalize. The ruling featured a notable split among the judges, with opinions from Circuit Judge James C. Ho and dissenting views from Judge Oldham. The case, Environment Texas Citizen Lobby v. ExxonMobil, highlights ongoing environmental regulatory challenges faced by the oil giant.
