More on US Supeme Court ruling to consider constitutionality of lethal injection:  Robert Barnes has coverage for the Washington Post here.  David Stout has this article in the New York Times.  Jim Malone has this coverage for Voice of America.

VOA excerpt:
...Whichever way the Supreme Court rules could have a far-reaching impact on the use of lethal injection to carry out capital punishment sentences in the United States.

Richard Dieter is executive director of the Death Penalty Information Center, which opposes capital punishment.

"There is going to be a need to hold up executions until there is further clarity," he said. "You would have to err on the side of caution if you are about to execute somebody with lethal injection. This might be a very broad ruling." ...

NYT excerpts;
...The step could have the effect of postponing executions across the country scheduled to be performed by lethal injection, the method is used by nearly all states with a death penalty, as well as by the federal government.

...“This is huge news, which could (and probably should) lead to a de facto moratorium on all lethal-injection executions nationwide until the Supreme Court issues a ruling,” Douglas A. Berman, a professor at the Moritz College of Law at Ohio State University and an authority on sentencing, wrote today on his blog.
