The Supreme Court took action in two capital cases Tuesday, with dissenting justices from the right and left pricking their colleagues in dissent.

In one, the court ordered the resentencing of a convicted Arizona killer because the jury was not told that if he were sentenced to life in prison, there was no chance he would be paroled. And in the other, the court declined to hear a broad constitutional challenge to the death penalty.

In the Arizona case, the court reiterated that when the prosecution makes a capital defendant's "future dangerousness" an issue, and the only sentencing alternative to death is life without parole, the jury must be instructed that the defendant is ineligible for release.

The court rejected the state's argument that the possibility of parole always exists because the legislature might change the law some day to permit it. The six-justice majority said that accepting that argument would mean that juries would never have to be informed that life in prison means what it says.

Justices Clarence Thomas and Samuel Alito dissented, calling the unsigned majority opinion "nonsense." Writing for the two, Justice Thomas said the majority's decision "is a remarkably aggressive" use of the court's power to review the decisions of the states' highest courts.

In a second capital case, this one from Louisiana, the court declined to undertake a broad constitutional review of the death penalty.
