What standard governs a court of appeals' factual-sufficiency review of evidence supporting a criminal conviction?
Holding
A court must neutrally consider all the evidence and ask whether a rational jury was justified in finding guilt beyond a reasonable doubt; factual insufficiency may arise either because the supporting proof is too weak by itself or because contrary proof creates reasonable doubt.
Reasoning
The Court reconciled its prior factual-sufficiency cases with the State's burden to prove every element beyond a reasonable doubt. Earlier formulations borrowed civil-law language asking whether a verdict was against the great weight and preponderance of the evidence. That language was potentially misleading because a criminal conviction cannot stand merely because evidence favoring guilt outweighs contrary evidence; the proof must establish guilt beyond a reasonable doubt.
The Court identified one controlling question: after viewing all evidence in a neutral light, could a rational jury have found guilt beyond a reasonable doubt? The evidence can fail that test in two distinct ways. First, the evidence favoring guilt, considered alone, may be too weak to support a finding beyond a reasonable doubt. Second, even if the State's proof is facially adequate, contrary evidence may be sufficiently strong that a rational jury could not have found guilt beyond a reasonable doubt.
This standard preserves meaningful factual review while respecting the jury's role as factfinder. An appellate court gives appropriate deference to credibility and demeanor determinations, may not substitute its own fact findings for the jury's, and, when it finds factual insufficiency, may only reverse and remand for a new trial. The Court of Criminal Appeals reviews whether the intermediate court used the proper standard; it does not itself redo the factual-sufficiency analysis.
