State of Minnesota v. Julian Sanchez-Sanchez, 879 N.W.2d 324

Sanchez‑Sanchez pleaded guilty to conspiracy to commit first‑degree sale of methamphetamine; state sought upward durational departure based on three alleged aggravating factors.
He waived a jury determination under Blakely and elected a Blakely court trial before the judge; no party objected when the district court declined to apply the Minnesota Rules of Evidence.
The State presented its case through a single witness, an FBI agent, who recounted wiretap evidence, co‑conspirator statements, and other investigatory materials linking Sanchez‑Sanchez to about 16 pounds of methamphetamine.
The district court found all three aggravating factors beyond a reasonable doubt and imposed a 240‑month sentence (well above the 74–103 month presumptive range).
The court of appeals affirmed, holding the rules of evidence do not apply to sentencing proceedings without a jury and that Rodriguez was limited to jury sentencing trials.
The Minnesota Supreme Court granted review to decide whether the Minnesota Rules of Evidence apply to Blakely court trials and whether the unobjected‑to failure to apply them was plain error.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Do the Minnesota Rules of Evidence apply to a Blakely court trial (judge as factfinder)?	Sanchez‑Sanchez: Yes — Blakely trials adjudicate facts and thus are not the "sentencing" exception in Minn. R. Evid. 1101(b)(3).	State: Rules do not apply to sentencing proceedings without a jury; Rodriguez limited application to jury sentencing trials.	The rules of evidence apply to all Blakely trials, whether judge or jury.
Was the district court’s unobjected‑to failure to apply the rules of evidence plain error?	Sanchez‑Sanchez: Yes — admission of hearsay from co‑conspirators likely affected the outcome.	State: Lower courts reasonably read Rodriguez as limited to jury trials; error not clear or obvious.	Error occurred but was not "plain" because prior precedent did not make the rule clear.
Should the sentence be vacated/remanded for a new Blakely trial due to the evidence errors?	Sanchez‑Sanchez: The hearsay admissions prejudiced substantial rights; reversal and remand required.	State: Because error was not plain, no relief is warranted.	Because the error was not plain, the court affirmed (as modified) and did not remand.
Is the Confrontation Clause implicated by admission of co‑conspirator hearsay?	Sanchez‑Sanchez raised Confrontation Clause concerns on appeal.	State: Issue not presented for review here.	Court declined to reach the Confrontation Clause claim (not raised in petition for review).
