[JURIST] Michael Newdow's latest challenge that "under God" is unconstitutional was narrowed by US District Judge Lawrence Karlton [official profile] in Sacramento on Monday. After the US Supreme Court dismissed his lawsuit [JURIST report] against the Pledge of Alliance for lack of standing last June, Michael Newdow promised to file a similar suit [JURIST report] with different plaintiffs. Karlton ruled that the suit cannot seek to have the entire pledge and "under God" declared unconstitutional, but rather it should focus on whether or not the pledge is an unconstitutional endorsement of religion. An appeal of this limit is likely, but Karlton did not indicate a time period for a written ruling. AP has more.
