New Mexico v. MartinezAnnotate this Case
Defendants Isaac Martinez and Carla Casias were each indicted on one count of armed robbery and one count of conspiracy to commit armed robbery. Early in the investigation of the robbery, a police detective enlisted the help of the deputy district attorney, who prepared and authorized service of what purported to be judicial subpoenas duces tecum (the subpoenas) to obtain records of calls and text messages of suspects from their cellular telephone providers. These purported subpoenas represented on their face that they were issued in the name of the Eighth Judicial District Court, although at the time of their preparation and service there was no pending prosecution, court action, or grand jury proceeding. Over signature of the deputy district attorney, some of these purported subpoenas ordered production of “Call Detail Records, and Text Message Detail” for the specified phones, all ordered subscriber information, and all ordered production to the Taos Police Department with the warning, “IF YOU DO NOT COMPLY WITH THIS SUBPOENA, you may be held in contempt of court and punished by fine or imprisonment.” These early subpoenas were filed with the district court in a miscellaneous court docket, rather than a criminal or grand jury docket, but they were styled as “State of New Mexico, Plaintiff, vs. John Doe, Defendant.” The detective used information gained from the early subpoenas to obtain search warrants for additional evidence. In this case, the New Mexico Supreme Court addressed whether a court could dismiss an indictment because evidence considered by the grand jury had been developed through use of unlawful subpoenas. The Supreme Court confirmed “almost a century of judicial precedents in New Mexico” and held that, absent statutory authorization, a court may not overturn an otherwise lawful grand jury indictment because of trial inadmissibility or improprieties in the procurement of evidence that was considered by the grand jury.
