Summary
The Minnesota Supreme Court held that appellate review of a district court's probable-cause determination supporting a search warrant is deferential and asks whether the issuing judge had a substantial basis for concluding that probable cause existed. The court distinguished warrant-based searches from warrantless searches, for which probable-cause determinations are reviewed de novo, and reversed and remanded for application of the correct standard.

Questions Presented
- What standard of appellate review applies to a district court's probable-cause determination made when issuing a search warrant?
- Whether the Minnesota Court of Appeals erred by reviewing the warrant-based probable-cause determination de novo rather than deferentially.
Holdings
- An appellate court reviewing a district court's probable-cause determination made in connection with the issuance of a search warrant must afford the district court's determination great deference and review only whether the issuing judge had a substantial basis for concluding that probable cause existed.
- The deferential substantial-basis standard for reviewing probable-cause determinations supporting search warrants does not apply to probable-cause determinations made by police in connection with warrantless searches; those determinations are reviewed de novo.
Key quotations
“An appellate court reviews a district court's decision to issue a warrant only to consider whether the issuing judge had a substantial basis for concluding that probable cause existed.” (804)
“Our opinion today merely reaffirms that the standard of review appropriate for an appellate court reviewing a district court's probable cause determination made upon issuing a warrant is the deferential, substantial basis standard.” (805)
Factual background
Police executed a search warrant at Rick Allen Rochefort's residence on March 1, 1999, and seized methamphetamine and items used to manufacture methamphetamine. The warrant application relied in part on information from informants and two purchases of iodine crystals, a precursor used to manufacture methamphetamine. Rochefort was charged with three first-degree controlled-substance crimes, moved to suppress the evidence for lack of probable cause, and was convicted after a jury trial.
Procedural history
Police executed a search warrant at Rochefort's residence and seized methamphetamine and methamphetamine-production materials. The district court denied Rochefort's motion to suppress, concluding that the warrant was supported by probable cause, and Rochefort was convicted and sentenced to 98 months in prison. On appeal, the Minnesota Court of Appeals held that the warrant lacked probable cause after applying de novo review. The Minnesota Supreme Court reversed and remanded to the court of appeals to apply the deferential substantial-basis standard.
Remand instructions
The case was remanded to the Minnesota Court of Appeals to apply the deferential substantial-basis standard of review to the district court's probable-cause determination supporting issuance of the search warrant.
