What is the test for a writ of habeas corpus?

A writ of habeas corpus under 2254 may be granted only if the challenged state court ruling "resulted in a decision that was contrary to, or involved an unreasonable application of, clearly established Federal law," or "was based on an unreasonable determination of the facts in light of the evidence presented." 28 U.S.C. 2254(d). "We review de novo the denial of a petition for a writ of habeas corpus brought under . . . 2254." Jackson v. Albany Appeal Bureau Unit, 442 F.3d 51, 54 (2d Cir. 2006) (citation and internal quotation marks omitted).
