Here is the opinion in State v. Sanchez (N.M. App.).

An excerpt:

Defendant Ronald Sanchez was arrested by a Tesuque Pueblo police officer on property of the Tesuque Pueblo and charged in Santa Fe County Magistrate Court with aggravated driving while under the influence of intoxicating liquor or drugs (DWI), first offense, contrary to NMSA 1978, Section 66–8–102 (2010). The officer was cross-commissioned as a Santa Fe County special deputy sheriff. His salary was paid by the Tesuque Pueblo Police Department, and it included incremental pay financed from a grant to assist the department in targeting the motoring public. On appeal to the district court, Defendant was again convicted. He appeals his conviction to this Court, contending that the district court (1) erred in denying his motion to suppress by holding that the tribal officer who conducted the arrest was properly cross-commissioned and had authority to arrest Defendant under the Motor Vehicle Code; and (2) erred in denying Defendant’s defense, pursuant to NMSA 1978, Section 66–8–137(B) (1978), and holding that the tribal officer did not have financial incentive motivating his arrest of Defendant. We hold that (1) the tribal officer was properly cross-commissioned and could properly arrest Defendant while wearing the uniform of and receiving his salary from the Tesuque Pueblo Police Department, and (2) the tribal officer’s receipt of pay from a grant and his obligation under the grant to make monthly statistical reports did not give rise to a defense under Section 66–8–137(B). We affirm Defendant’s conviction.
