What it's about

Henry L. Watson III asks the Supreme Court to review his Wisconsin criminal case, arguing that the jury instructions and the State’s later interpretation of Wisconsin law prevented the jury from properly considering his self-defense claim. He also argues that the conflict between the statute and jury instruction violated due process and that his trial lawyer was ineffective for failing to object.

Question presented

1. Whether Wisconsin Jury Instruction 820, which instructed the jury to consider perfect self-defense in evaluating Count 1, violated Boy de and Mullaney when the jury failed to consider self-defense, and the State was unconstitutionally relieved of its burden to disprove it; and violated Lockett when the State ’ s statutory interpretation barred consideration of constitutionally relevant evidence. 2. Whether a conflict between a criminal statute and its corresponding jury instruction creates statutory vagueness and ambiguity requiring judicial review of legislative history under the Due Process Clause. 3. Whether trial counsel rendered ineffective assistance under Strickland by pursuing an improper civil remedy and failing to object to the jury ’ s disregard of the instruction and the State ’ s post-verdict reinterpretation of the statute. 4. Whether, under Estelle v. McGuire, a state law violation that categorically barred the jury ’ s consideration of self-defense under Wis. Stat. § 939.48(3) and contradicted Wisconsin Jury Instruction 820 rises to a federal constitutional violation requiring review by this Court.

Briefing

What it's about

Henry L. Watson III asks the Supreme Court to review his Wisconsin criminal case. He says jury instructions and the State's later reading of Wisconsin law kept jurors from properly considering his self-defense claim.

Argument

The petition for certiorari (the Court's decision whether to hear a case) has been filed, and oral argument is not yet scheduled. Watson argues that the jury failed to consider self-defense and that his lawyer failed to object; no Supreme Court vote has occurred.

Impact

The case could affect defendants who say jurors were blocked from considering self-defense evidence. For example, a person convicted after a disputed self-defense instruction could point to the Court's response in seeking review.

What is at stake in Watson v. Mason?

Watson says jurors did not properly weigh his self-defense claim. He asks the Court to examine whether that violated constitutional protections.

Who could be affected by Watson's self-defense challenge?

Criminal defendants who raise self-defense could be affected. The case concerns whether jury instructions improperly prevented jurors from considering that defense.

What happens next in Watson v. Mason?

The Court will decide whether to grant certiorari, meaning it will hear the case. Oral argument has not been scheduled.
