A broad-based challenge to the integrity of the proceedings due to the incapacity of the judge is properly construed as a successive habeas filing rather than a motion to revisit the verdict, as the challenge doesn't arise from a cognizable procedural flaw in the earlier state trial, direct appeal or collateral proceedings. Where the impacts of the alleged incapacity have already been litigated, permission to file for te writ is appropriately denied.
