Texas is the only state besides Oklahoma to have a bifurcated appellate system at the highest level. The Texas Supreme Court hears appeals involving civil matters (which include juvenile cases), and the Texas Court of Criminal Appeals hears appeals involving criminal matters. Sometimes, the dividing line is murky, especially with respect to jurisdiction in mandamus and habeas corpus cases. See, e.g. Justice Willett's dissent in "In re Reece", 341 S.W.3d 360 (Tex. 2011) (orig. proceeding). The Texas Supreme Court and the Texas Court of Criminal Appeals are co-equal, unlike in Oklahoma where the Supreme Court is superior to the highest criminal court.
