The US Supreme Court [official website] granted certiorari [order list, PDF] in four cases on Tuesday. In City and County of San Francisco v. Sheehan [docket; cert. petition, PDF] the court has been asked to decide whether Title II of the Americans with Disabilities Act [text] requires law enforcement to accommodate a mentally ill, violent and armed suspect when taken into custody. The court will also determine if it is unreasonable under the Fourth Amendment [text] for law enforcement to enter into a residence based on the belief that the suspect inside is armed and will violently resist arrest.

The court has also consolidated three cases against the Environmental Protection Agency (EPA) [official website]: Michigan v. EPA [docket; cert. petition, PDF], Utility Air Regulatory Group v. EPA [docket; cert. petition, PDF] and National Mining Association v. EPA [docket; cert. petition, PDF]. The court will determine whether the EPA unreasonably refused to take into account costs when addressing whether they should regulate air pollutants emitted by electric utilities. All three cases address the statutory interpretation of “appropriate” in regards to determining costs addressing regulations of hazardous pollution under the hazardous air pollutants statute [42 USC § 7412(n)(1)(A)].
