Justice Breyer agreed that a possible Heck bar does not prevent a § 1983 claim from accruing and that a district court could stay a timely filed civil case pending related criminal proceedings. He disagreed, however, with requiring criminal defendants to file civil actions immediately to preserve them.
He would allow equitable tolling when a plaintiff reasonably asserts that the alleged constitutional violation was, or would be, necessary to the criminal conviction. Tolling would run from the filing of charges through the end of the prosecution and, after conviction, through direct review, state collateral proceedings, and federal habeas proceedings in which the plaintiff pursued that issue.
This approach would avoid forcing defendants to divide their attention between criminal defense and civil litigation, reduce the risk of inconsistent federal and state determinations, and prevent unnecessary protective § 1983 filings. State criminal proceedings could first resolve or narrow constitutional issues, and preclusion would eliminate many meritless civil claims.
Justice Breyer rejected the majority's concern about uncertainty and delayed notice. In his view, the tolling rule would be clear: tolling would continue while the relevant issues were being litigated in state court. The State and usually the officers would have notice through those proceedings, while avoiding the immediate cost and disruption of a federal civil suit. He would have vacated and remanded for consideration of equitable tolling.
