Some of the provisions that the CA statute involving emissions violates federal law as it curbs production of certain gasses; the feds have already set manditory lmits which cannot be adjusted by the states. Or actually the feds may have set a limit and state's can't exceed it, i'm not sure As for CA and OR boh cases violate federal law or are isues which are to be decied by the federal governent not state's righs issues; it just isn't the jurisdction of the state. As for Bush over-riding the rights of state's, if he did then he would have gone into LA after Katrina irrelevant of protest by the Governor.
