Yeah it is pretty interesting, I read about it a long time ago and having trouble with the search engines, but some kid found a discrepancy between the ND constitution and the US constitution, which was quickly amended and fixed in 2012 (not 1997 as I thought). Basically the ND constitution didn't require the governor to take an oath of allegiance to the US, which the US constitution requires all state constitutions to require officers of the state to do.
