On May 3, 2019, the Texas Supreme Court issued a significant administrative law ruling in the case of Mosely v. Texas Health and Human Services Commission. The court held, unsurprisingly, that under the Texas Administrative Procedure Act (Texas APA), an appellant seeking review of an administrative action must first file a petition for rehearing with the Administrative Law Judge, “unless another statute plainly provides otherwise.” However, when the agency, as here, provided seriously incorrect information to the appellant about the proper procedures to follow to seek review of an adverse order, that action can, “under some circumstances,” violate the appellant’s constitutional right to due process.
