State v. Watkins, 274 P.3d 1279

Watkins was convicted in 2005 of lewd conduct with a minor; conviction reversed for new trial due to inadmissible hearsay DNA evidence.
Before remand, witnesses were cautioned not to mention there had been a prior trial and appeal.
At the second trial, a police officer testified and during cross-examination referenced a prior trial; the court paused to address the issue outside the jury.
The district court declined to grant a mistrial, deeming a curative instruction sufficient, and instructed the jury to not speculate about the prior trial.
Watkins was convicted after the curative instruction; he appeals, arguing denial of a mistrial violated his Sixth and Fourteenth Amendment rights.
The appellate court conducts a harmless error analysis, concluding the improper disclosure was harmless in light of overwhelming guilt evidence.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Did the disclosure of a prior trial require an ipso facto mistrial?	Watkins argues disclosure was inherently prejudicial and mandated mistrial.	Watkins contends the disclosure was highly prejudicial and requires reversal.	No ipso facto mistrial; harmless error analysis applied.
Is a curative instruction dispositive of the error?	State contends presumption of following curative instruction ends inquiry.	Watkins argues curative instruction cannot cure substantial prejudice.	Presumption is not dispositive; review remains for harmless error.
Was the error harmless beyond a reasonable doubt?	Watkins concedes some prejudice but argues it affected fairness.	State emphasizes overwhelming evidence against Watkins and protective curative instruction.	Yes; error was harmless given overwhelming evidence and curative instruction.
