Nev. Rev. Stat. § 179.105
All property or things taken on a warrant must be retained in an officer's custody, subject to the order of the court to which the officer is required to return the proceedings before the officer, or of any other court in which the offense in respect to which the property or things are taken is triable. If it appears that the property taken is not the same as that described in the warrant, that there is no probable cause for believing the existence of the grounds on which the warrant was issued or that the property is determined pursuant to NRS 179.11518 to be subject to the attorney-client privilege, the magistrate shall cause it to be restored to the person from whom it was taken. However, no search warrant shall be quashed by any magistrate or judge within this State nor shall any evidence based upon a search warrant be suppressed in any criminal action or proceeding because of mere technical irregularities which do not affect the substantial rights of the accused.
