Facts

• Defendants Isaac Martinez and Carla Casias were indicted on charges of armed robbery and conspiracy to commit armed robbery. Early in the investigation, a police detective, with the assistance of a deputy district attorney, used purported judicial subpoenas duces tecum to obtain call and text message records from the suspects' cellular providers without a pending prosecution, court action, or grand jury proceeding. This information led to further evidence and ultimately to the grand jury indictments of the defendants. Defendants moved to quash the indictment or suppress evidence obtained through these subpoenas, arguing the subpoenas were unlawfully issued (paras 2-6).

Procedural History

• Eighth Judicial District Court: The court granted Defendants' motion and quashed the indictment, reasoning that the subpoenas were unlawful and tainted the grand jury proceedings (para 6).
• Court of Appeals: Certified the issue to the Supreme Court of New Mexico due to a conflict between judicial precedents and a recent amendment to the Rules of Criminal Procedure (para 7).

Parties' Submissions

• Plaintiff-Appellant (State of New Mexico): Argued that an otherwise lawful grand jury indictment should not be overturned due to the trial inadmissibility or improprieties in the procurement of evidence considered by the grand jury (para 1).
• Defendant-Appellee (Isaac Martinez and Carla Casias): Argued for the quashing of the indictment or suppression of all evidence obtained through the use of contested subpoenas, claiming the subpoenas were unlawfully issued and tainted the grand jury proceedings (para 6).

Legal Issues

• Whether a court may dismiss an indictment because evidence considered by the grand jury had been developed through the use of unlawful subpoenas (para 1).
• Whether the Rules of Criminal Procedure allow for a post-indictment review of the lawfulness, competency, and relevancy of evidence considered by the grand jury (paras 7, 34).

Disposition

• The Supreme Court of New Mexico reversed the order of dismissal by the district court and remanded the matter for further proceedings, holding that the district court lacked authority to review the admissibility of evidence considered by the grand jury (para 39).

Reasons

• The Supreme Court, with Justice Charles W. Daniels writing for a unanimous court, held that nearly a century of judicial precedents in New Mexico confirmed that, absent statutory authorization, a court may not overturn an otherwise lawful grand jury indictment due to trial inadmissibility or improprieties in the procurement of evidence considered by the grand jury. The Court recognized the subpoenas as unlawfully issued but distinguished between the disciplinary action against the attorneys involved and the procedural consequences of their use. The Court reviewed the legislative and judicial history regarding the grand jury process, emphasizing the independence of the grand jury and the impracticality of post-indictment evidence reviews. It concluded that neither the New Mexico grand jury statutes nor case law authorized judicial review of the evidence considered by the grand jury, except for its sufficiency and then only upon a showing of prosecutorial bad faith. The Court also decided to amend Rule 5-302A(F) to conform to established law, removing language that suggested broader review authority than historically permitted (paras 1-38).
