This measure would give the Attorney General the exclusive right to challenge the validity of a certified EIR through the courts. No other person, state or local agency, or other organization would be able to challenge the EIR. The measure would apply prospectively and retroactively—that is, the restriction on challenges would apply both to challenges of EIRs certified after the effective date of the measure and to challenges started before the effective date of the measure provided that no final judgment has been entered by a court for which a further appeal would not be possible.
