Justices will consider the case that revolves around the role of multiple IQ scores in determining an Alabama murderer’s eligibility for capital punishment.

The U.S. Supreme Court agreed on Friday to hear an appeal by Alabama officials of a judicial decision that a man convicted of a 1997 murder is intellectually disabled - a finding that spared him from the death penalty - as they press ahead with the Republican-governed state's bid to execute him.

Decades ago, the Court said inmates who are intellectually disabled can't be executed. Now, it will weigh the use of intelligence tests in death penalty cases.
