Antonin Scalia, a sitting U.S. Supreme Court Justice, has died [bbc.com]:
US Supreme Court Justice Antonin Scalia - one of most conservative members of the high court - has died. Justice Scalia's death could shift the balance of power on the US high court, allowing President Barack Obama to add a fifth liberal justice to the court. The court's conservative majority has recently stalled major efforts by the Obama administration on climate change and immigration.
Justice Scalia, 79, was appointed by President Ronald Reagan in 1986. He died in his sleep early on Saturday while in West Texas for [a] hunting trip, the US Marshall service said. Justice Scalia was one of the most prominent proponents of "originalism" - a conservative legal philosophy that believes the US Constitution has a fixed meaning and does not change with the times.
