Opinion of the Court
"In those cases, the constitutional defect lay in the fact that relevant mitigating evidence was placed beyond the effective reach of the sentencer. In Lockett, Eddings, Skipper, and Hitchcock, the sentencer was precluded from even considering certain types of mitigating evidence. In Penry, the defendant's evidence was placed before the sentencer but the sentencer had no reliable means of giving mitigating effect to that evidence. In this case, however, Graham's mitigating evidence was not placed beyond the jury's effective reach." Graham, 506 U. S., at 475.
In addition, we held that Graham's case differed from Penry in that "Graham's evidence—unlike Penry's—had mitigating relevance to the second special issue concerning his likely future dangerousness." 506 U. S., at 475. We concluded that, even with the benefit of the subsequent Penry decision, reasonable jurists at the time of Graham's sentencing "would [not] have deemed themselves compelled to accept Graham's claim." 506 U. S., at 477. Thus, we held that a ruling in favor of Graham would have required the impermissible application of a new rule under Teague. 506 U. S., at 477.

Today we are asked to take the step that would have been a new rule had we taken it in Graham. Like Graham, petitioner contends that the Texas sentencing system did not allow the jury to give adequate mitigating effect to the evidence of his youth. Unlike Graham, petitioner comes here on direct review, so Teague presents no bar to the rule he seeks. The force of stare decisis, though, which rests on considerations parallel in many respects to Teague, is applicable here. The interests of the State of Texas, and of the victims whose rights it must vindicate, ought not to be turned aside when the State relies upon an interpretation of the Eighth Amendment approved by this Court, absent demonstration that our earlier cases were themselves a mis-
