But, this decision may be sensible, as the Congress during its 2009 Joint Session was most clearly charged as the ultimate guardian of our Constitution (see 3 USC 15):
Were the courts of 50 states at liberty to issue injunctions restricting certification of duly-elected presidential electors, the result could be conflicting rulings and delayed transition of power in derogation of statutory and constitutional deadlines.
Any investigation of eligibility is best left to each party, which presumably will conduct the appropriate background check or risk that its nominee's election will be derailed by an objection in Congress, which is authorized to entertain and resolve the validity of objections following the submission of the electoral votes,(emphasis added).
One officer of government's failure in their constitutional duties, or the failure of one group of constitutional officers, does not in any way excuse any other officer or group of officers from the discharge of their own sworn duties.
By the way, the California Secretary of State has removed at least one presidential candidate, Eldridge Cleaver, from the ballot before because he did not meet the Constitutional requirements. I believe it was in 1968.
