Whether obtaining new support for a previously available claim constitutes a new 'factual predicate' that restarts the one-year habeas petition filing clock under AEDPA

QUESTION PRESENTED A person in state custody has one year to file a habeas petition. Usually, that one year runs from “the date on which the judgment became final by the conclusion of direct review or the expiration of the time for seeking such review.” 28 U.S.C. §2244(d)(1)(A). But AEDPA restarts the clock in certain limited circumstances. Relevant here, the clock restarts when a previously undiscoverable “factual predicate” becomes discoverable to someone acting with “due diligence.” 28 U.S.C. §2244(d)(1)(D). When a prisoner obtains new support for a claim, does that mean she has a new “factual predicate” that restarts her clock?
