Bush challenges hundreds of laws

President Bush has quietly claimed the authority to disobey more than 750 laws enacted since he took office, asserting that he has the power to set aside any statute passed by Congress when it conflicts with his interpretation of the Constitution.

Among the laws Bush said he can ignore are military rules and regulations, affirmative-action provisions, requirements that Congress be told about immigration services problems, ''whistle-blower" protections for nuclear regulatory officials, and safeguards against political interference in federally funded research.

Legal scholars say the scope and aggression of Bush's assertions that he can bypass laws represent a concerted effort to expand his power at the expense of Congress, upsetting the balance between the branches of government. The Constitution is clear in assigning to Congress the power to write the laws and to the president a duty ''to take care that the laws be faithfully executed." Bush, however, has repeatedly declared that he does not need to ''execute" a law he believes is unconstitutional.

Bush is the first president in modern history who has never vetoed a bill, giving Congress no chance to override his judgments. Instead, he has signed every bill that reached his desk, often inviting the legislation's sponsors to signing ceremonies at which he lavishes praise upon their work.

Then, after the media and the lawmakers have left the White House, Bush quietly files ''signing statements" -- official documents in which a president lays out his legal interpretation of a bill for the federal bureaucracy to follow when implementing the new law. The statements are recorded in the federal register.

In his signing statements, Bush has repeatedly asserted that the Constitution gives him the right to ignore numerous sections of the bills -- sometimes including provisions that were the subject of negotiations with Congress in order to get lawmakers to pass the bill. He has appended such statements to more than one of every 10 bills he has signed.
