(Jan 18, 2008) Montana governor Brian Schweitzer (D) declared independence Friday from federal identification rules and called on governors of 17 other states to join him in forcing a showdown with the federal government which says it will not accept the driver's licenses of rebel states' citizens starting May 11.

If that showdown comes to pass, a resident of a non-complying state could not use a driver's license to enter a federal courthouse or a Social Security Administration building nor could he board a plane without undergoing a pat-down search, possibly creating massive backlogs at the nation's airports and almost certainly leading to a flurry of federal lawsuits.

States have until May 11 to request extensions to the Real ID rules that were released last Friday. They require states to make all current identification holders under the age of 50 to apply again with certified birth and marriage certificates.

The rules also standardize license formats, require states to interlink their DMV databases and require DMV employee to undergo background checks.
