CHRISTIAN SCIENCE MONITOR: Mumia Abu-Jamal, whose death sentence for killing a Philadelphia police officer in 1981 has become an international cause célèbre for opponents of capital punishment, has suffered a significant setback at the US Supreme Court. In a summary order issued on Tuesday, the high court reversed a 2008 federal appeals court ruling that had required a new sentencing hearing for Mr. Abu-Jamal. The Supreme Court action sends the case back to the Third US Circuit Court of Appeals in Philadelphia to reconsider the issue in light of a similar decision handed down last week by the high court. In that case, with similar facts, the justices voted 9 to 0 to reverse an order that struck down the death sentence. Tuesday’s action by the Supreme Court likely moves Abu-Jamal significantly closer to execution. MORE
