Petitioner James Williams appeals the district court's dismissal of his petition for a writ of habeas corpus. After considering Williams' arguments, we affirm the judgment of the district court and vacate the stay of execution entered by the district court pending this appeal.

Williams was convicted of killing Mohamad Youssef Awada. Since the murder was committed while robbing Awada, Williams was charged with a capital murder under Texas law. See Tex. Penal Code Ann. Sec. 19.03(a)(2).1 After the punishment phase hearing the jury answered affirmatively the special issues submitted to them.2 Accordingly, Williams was sentenced to death. Williams' conviction was affirmed by the Texas Court of Criminal Appeals. Williams v. State, 604 S.W.2d 146 (Tex.Crim.App.1980) (en banc). After exhausting his state remedies, Williams filed an application for a writ of habeas corpus and a motion for a stay of execution in federal district court. The district court granted the stay of execution on January 26, 1981. On January 8, 1986, an evidentiary hearing was held before the magistrate. The magistrate rejected each of Williams' claims and recommended that his petition for habeas corpus be dismissed. The district court adopted the opinion of the magistrate and entered an order on May 27, 1986, dismissing Williams' petition. On August 1, 1986, the district court granted Williams a certificate of probable cause as well as permission to proceed in forma pauperis. The district court also continued the stay of execution pending the disposition of this appeal.

Williams first contends that the evidence of unadjudicated criminal conduct submitted to the jury at the punishment phase of the trial violates the eighth and fourteenth amendments. Williams also asserts that the equal protection clause of the fourteenth amendment is violated because Texas allows for the introduction of unadjudicated offenses in capital sentencing trials but not in noncapital cases. We discuss the merits of each contention in turn.

In the punishment phase of Williams' trial, evidence was introduced regarding Williams' participation in an armed robbery of a restaurant less than two weeks prior to the time he murdered Awada.3 Williams contends that because there was no evidence that he was either charged or convicted for the offense, such evidence lacks reliability and results in an arbitrary imposition of the death penalty in violation of the eighth and fourteenth amendments. We disagree.

We have already rejected the argument advanced by Williams in Milton v. Procunier, 744 F.2d 1091 (5th Cir.1984), cert. denied, 471 U.S. 1030, 105 S. Ct. 2050, 85 L. Ed. 2d 323 (1985). In Milton the state put evidence of unadjudicated criminal conduct before the jury during the punishment phase of a capital trial. We rejected the contention of the habeas petitioner that the admission of this evidence violated his rights under the fifth, sixth, eighth, and fourteenth amendments. Id. at 1093, 1097. We noted that under the structure of the Texas death penalty system, a jury must find that a murder was committed under one of the circumstances defined in Tex.Penal Code Ann. Sec. 19.03(a) before it considers whether to impose the death penalty. Id. at 1097 n. 5 (quoting Autry v. Estelle, 706 F.2d 1394, 1406 n. 5 (5th Cir.1983), cert. denied, 465 U.S. 1085, 104 S. Ct. 1458, 79 L. Ed. 2d 906 (1984)). We concluded that the structure of the Texas death penalty system and the admission of unadjudicated criminal conduct during the punishment phase "in no way undermines the constitutionally mandated procedures set forth by the Supreme Court in Jurek [v. Texas, 428 U.S. 262, 96 S. Ct. 2950, 49 L. Ed. 2d 929 (1976) ], and [Gregg v. Georgia, 428 U.S. 153, 96 S. Ct. 2909, 49 L. Ed. 2d 859 (1976) ]." Id.

We emphasize that evidence of Williams' extraneous unadjudicated offense was not allowed to be introduced until the punishment phase and thus eliminates any concern that the jury used this unadjudicated offense to influence its decision in the guilt phase of the trial. The focus of the Texas capital sentencing procedure is to have all the relevant evidence before the jury when answering the special issues which determine whether the death penalty will be imposed. Jurek, 428 U.S. at 276, 96 S.Ct. at 2958. Acknowledging society's reservations about the use of wrongdoing not then being tried, we stated in Milton that these concerns "are addressed by properly applied standards of relevance and sufficiency of proof." 744 F.2d at 1097.4 As Justice Stevens said in Barclay v. Florida, 463 U.S. 939, 103 S. Ct. 3418, 77 L. Ed. 2d 1134 (1983):

[T]he Constitution does not prohibit consideration at the sentencing phase of information not directly related to either statutory aggravating circumstances or statutory mitigating factors, as long as that information is relevant to the character of the defendant or the circumstances of the crime ... What is important at the selection stage is an individualized determination on the basis of the character of the individual and the circumstances of the crime.

463 U.S. at 967, 103 S. Ct. at 3433 (Stevens, J., joined by Powell, J., concurring in the judgment) (quoting in part Zant v. Stephens, 462 U.S. 862, 879, 103 S. Ct. 2733, 3440, 77 L. Ed. 2d 235 (1983) (emphasis added by Zant )) (citations omitted).

Evidence of these unadjudicated crimes is clearly relevant to the jury's task of determining whether there is a probability that Williams would continue to commit acts of violence as required by special question two. Consistent with our decision in Milton, we hold that the admission of unadjudicated offenses in the sentencing phase of a capital trial does not violate the eighth and fourteenth amendments.5

Williams also alleges that because Texas allows for the introduction of unadjudicated offenses in capital sentencing trials but does not allow such evidence in noncapital cases, the Texas capital sentencing procedure violates the equal protection clause of the fourteenth amendment. We reject this argument.

Our first task in an equal protection challenge is to identify the level of scrutiny that must be used. Williams' complaint is that capital defendants are treated differently from noncapital defendants. We agree with Williams that the rational basis test should be used to test Texas' sentencing procedure; we have already held that capital defendants are not a suspect class for equal protection purposes. Gray v. Lucas, 677 F.2d 1086, 1104 (5th Cir.1982), cert. denied, 461 U.S. 910, 103 S. Ct. 1886, 76 L. Ed. 2d 815 (1983).

Rational basis scrutiny requires only that the legislative classification rationally promote a legitimate governmental objective. Arceneaux v. Treen, 671 F.2d 128, 131 (5th Cir.1982). This constitutional standard is "offended only if the classification rests on grounds wholly irrelevant to the achievement of the state's objective." Id. at 132 (quoting McGowan v. Maryland, 366 U.S. 420, 425, 81 S. Ct. 1101, 1105, 6 L. Ed. 2d 393 (1961)). We believe that Texas' capital sentencing procedure passes constitutional muster under the rational basis standard. The purpose of allowing evidence of nonadjudicated offenses to be considered in the sentencing phase is to assist the jury in determining whether the defendant is likely to be a continuing threat to society. This evidence helps focus the jury on the particular circumstances of the individual offense and the individual offender. Jurek, 428 U.S. at 273, 96 S.Ct. at 2957. Given the finality of a death sentence, Texas has a strong interest in ensuring that all relevant evidence concerning the capital defendant is placed before the jury so that it can consider the evidence when answering the special issues. In furthering this interest, the state could rationally decide that different procedures should be used for capital defendants than for noncapital defendants. Consequently, we reject Williams' assertion that Texas' capital sentencing procedures violates the equal protection clause of the fourteenth amendment.

Finding all of Williams' claims to be without merit, the judgment of the district court dismissing Williams' habeas petition is AFFIRMED and the stay of execution issued by the district court is VACATED.

AFFIRMED; STAY OF EXECUTION VACATED.
