In brief
Overview
The petitioner argues that the conduct set forth in the initial petition should be treated as the core operative facts for constitutional violations and that a relation‑back rule is superior to the Ninth Circuit’s approach.
According to Ms. Blatt, the respondent contends that habeas petitions must meet heightened pleading requirements, identifying all grounds and facts, and that the relevant conduct is the set of facts supporting the specific grounds for relief.
According to Ms. Blatt, the respondent also argues that the transaction or occurrence in the habeas context should be narrowly defined, focusing on police misconduct rather than counsel performance.
The Court notes that the statute of limitations is a strict defense that applies regardless of timing, prejudice, or motive.
According to United States (amicus curiae), an amicus brief argues that the relevant conduct in a habeas petition is the set of facts supporting the particular grounds for relief, preserving the reference point.
