Introduction
In Washington criminal trials, proper jury instructions are not just procedural—they are constitutional safeguards. The case of State v. Blancaflor highlights how a Washington jury instruction error can lead to reversal of a conviction when jurors are not properly directed after changes to the jury panel.
This case serves as an important reminder that even seemingly small procedural missteps can undermine a defendant’s right to a fair trial.

Background of State v. Blancaflor
In this case, Othniel and Cynthia Blancaflor were involved in the operation of an adult care facility in Pierce County. They were later charged and convicted of criminal offenses related to that operation.
During jury deliberations, an issue arose when a juror was replaced with an alternate juror after deliberations had already begun. This created what courts refer to as a “reconstituted jury.”
The Washington Jury Instruction Error
Failure to Instruct the Reconstituted Jury
The key legal issue was whether the trial court properly instructed the jury after replacing a juror. Washington law requires that when a new juror joins deliberations, the court must clearly instruct the jury to:
- Disregard prior deliberations, and
- Begin deliberations anew
In Blancaflor, the trial court failed to give this instruction on the record.
Why This Matters
This requirement exists to protect the defendant’s constitutional right to a unanimous verdict. If a new juror joins ongoing deliberations without restarting the process, that juror may be influenced by discussions they did not fully participate in.
Constitutional Implications
Right to a Unanimous Jury
Washington law guarantees criminal defendants the right to a unanimous jury verdict. When deliberations are not restarted after a juror substitution, that right may be compromised.
The Court of Appeals held that this type of error is:
- A constitutional error, and
- A manifest error that can be raised for the first time on appeal
Burden on the State
Once such an error is identified, the burden shifts to the State to prove that the error was harmless beyond a reasonable doubt.
In this case, the State failed to meet that burden.
Court of Appeals Decision
Reversal of Conviction
Because the trial court did not properly instruct the reconstituted jury, the Court of Appeals reversed the convictions.
The court emphasized that:
- Jury instructions must be clearly given on the record
- Courts cannot assume jurors understood they needed to restart deliberations
- Constitutional protections take priority over procedural convenience
Why This Case Matters in Washington Law
Strict Compliance with Jury Procedures
This case reinforces that Washington courts require strict compliance with jury instruction rules—especially when constitutional rights are involved.
Practical Takeaways
For defendants and attorneys, Blancaflor highlights:
- Jury errors can be raised even if not objected to at trial
- Appellate courts closely scrutinize jury procedures
- Trial courts must follow precise steps when modifying jury composition
For judges, the case is a reminder that even routine procedural steps must be handled carefully and documented clearly.
Washington Jury Instruction Error: Key Lessons
1. Always Restart Deliberations After Juror Replacement
Failure to do so risks reversal.
2. Instructions Must Be On the Record
Unrecorded assumptions are not enough.
3. Constitutional Errors Are Hard to Overcome
The State must prove harmlessness beyond a reasonable doubt.
