B. M. says the finding burdens First Amendment petitioning and Second Amendment rights based on lawful conduct; the Supreme Court has not agreed to review that claim.

Summary: written with AI from the case record.

What it's about

The petition asks whether a state may weigh lawful conduct, including court filings, when deciding that someone is dangerous and limiting constitutional rights.

Question presented

1. Whether, as applied here, the First, Second, and Fourteenth Amendments permit a State to employ a totality-of-the-circumstances methodology that transforms concededly lawful conduct into a constitutionally sufficient finding of dangerousness, thereby authorizing the burdening of enumerated constitutional rights without an objectively sufficient present predicate. 2. Whether the First Amendment permits a State to rely upon lawful petitioning activity as a component of a judicial dangerousness determination where the litigation activity was not found to be frivolous, unlawful, or otherwise outside constitutional protection. 3. Whether the Second Amendment, as interpreted in New York State Rifle & Pistol Ass'n v. Bruen and United States v. Rahimi, permits the continued burdening of the right to keep and bear arms where the dangerousness determination rests upon a methodology that aggregates lawful, non-threatening conduct rather than an objectively sufficient present predicate demonstrating a credible threat of physical harm.

What happens next

The Court's next step is to decide whether to hear B. M.'s petition. No oral argument or decision date is scheduled.
