A federal judge on Tuesday dismissed Liberty University's lawsuit challenging the Obama administration's new federal health care law, declaring that a provision requiring most individuals to obtain insurance is constitutional.The ruling by U.S. District Judge Norman K. Moon in Lynchburg is the second court decision upholding the law, following one in Michigan in October. University law school dean Mathew Staver said in a telephone interview that he will promptly appeal the ruling to the 4th U.S. Circuit Court of Appeals in Richmond.
