What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Opinion:
CAGE v. LOUISIANA
No. 89-7302.
Decided November 13, 1990
Per Curiam.
The motion of petitioner for leave to proceed informa pau-peris and the petition for a writ of certiorari are granted.
In state criminal trials, the Due Process Clause of the Fourteenth Amendment “protects the accused against conviction except upon proof beyond a reasonable doubt of every fact necessary to constitute the crime with which he is charged.” In re Winship, 397 U. S. 358, 364 (1970); see also Jackson v. Virginia, 443 U. S. 307, 315-316 (1979). This reasonable-doubt standard “plays a vital role in the American scheme of criminal procedure.” Winship, 397 U. S., at 363. Among other things, “[i]t is a prime instrument for reducing the risk of convictions resting on factual error.” Ibid. The issue before us is whether the reasonable doubt instruction in this case complied with Winship.
Petitioner was convicted in a Louisiana trial court of first-degree murder and was sentenced to death. He appealed to the Supreme Court of Louisiana, arguing, inter alia, that the reasonable-doubt instruction used in the guilt phase of his trial was constitutionally defective. The instruction provided in relevant part:
“If you entertain a reasonable doubt as to any fact or element necessary to constitute the defendant’s guilt, it is your duty to give him the benefit of that doubt and return a verdict of not guilty. Even where the evidence demonstrates a probability of guilt, if it does not establish such guilt beyond a reasonable doubt, you must acquit the accused. This doubt, however, must be a reasonable one; that is one that is founded upon a real tangible substantial basis and not upon mere caprice and conjecture. It must be such doubt as would give rise to a grave uncertainty, raised in your mind by reasons of the unsatisfactory character of the evidence or lack thereof. A reasonable doubt is not a mere possible doubt. It is an actual substantial doubt. It is a doubt that a reasonable man can seriously entertain. What is required is not an absolute or mathematical certainty, but a moral certainty.” 554 So. 2d 39, 41 (La. 1989) (emphasis added).
The Supreme Court of Louisiana rejected petitioner’s argument. The court first observed that the use of the phrases “grave uncertainty” and “moral certainty” in the instruction, “if taken out of context, might overstate the requisite degree of uncertainty and confuse the jury. ” Ibid. But “taking the charge as a whole,” the court concluded that “reasonable persons of ordinary intelligence would understand the definition of ‘reasonable doubt.’” Ibid. It is our view, however, that the instruction at issue was contrary to the “beyond a reasonable doubt” requirement articulated in Winship.
In construing the instruction, we consider how reasonable jurors could have understood the charge as a whole. Francis v. Franklin, 471 U. S. 307, 316 (1985). The charge did at one point instruct that to convict, guilt must be found beyond a reasonable doubt; but it then equated a reasonable doubt with a “grave uncertainty” and an “actual substantial doubt,” and stated that what was required was a “moral certainty” that the defendant was guilty. It is plain to us that the words “substantial” and “grave,” as they are commonly understood, suggest a higher degree of doubt than is required for acquittal under the reasonable-doubt standard. When those statements are then considered with the reference to “moral certainty,” rather than evidentiary certainty, it becomes clear that a reasonable juror could have interpreted the instruction to allow a finding of guilt based on a degree of proof below that required by the Due Process Clause.
Accordingly, the judgment of the Supreme Court of Louisiana is reversed, and the case is remanded for further proceedings not inconsistent with this opinion.
It is so ordered.
Similar attempts to define reasonable doubt have been widely criticized by the Federal Courts of Appeals. See, e. g., Monk v. Zelez, 901 F. 2d 885, 889-890 (CA10 1990); United States v. Moss, 756 F. 2d 329, 333 (CA4 1985); United States v. Indorato, 628 F. 2d 711, 720-721 (CA1 1980); United States v. Byrd, 352 F. 2d 570, 575 (CA2 1965); see also Taylor v. Kentucky, 436 U. S. 478, 488 (1978).
