On August 2012, the Supreme Court of Justice of the Nation decided that even when the patient gave his/her consent for the use of anesthesia, damages caused for the use of such substance create liability for the doctor or institution that was in charge of the process. The court determined that in these cases there is a presumption that the damages caused by the anesthesia were originated by negligence, therefore the doctors that took part in the stages that cover the anesthetic care will have to submit arguments against those claims.
