(Credit: Michael Stravato for The Texas Tribune) AUSTIN, Texas – Texas is still temporarily barred from taking over Houston Independent School District, a state appellate court ruled Wednesday, upholding a lower court’s order. In a 2-1 ruling, the Texas Third Court of Appeals upheld a temporary injunction that stops the Texas Education Agency from replacing the elected school board of its largest district with an appointed board of managers. The appeals court ruling sends the case back to the lower court that in January blocked the state’s takeover effort.
