On February 12, sponsors of an initiative to impose maximum age limits on congressional candidates submitted their petition to the North Dakota Secretary of State. It needs 31,164 signatures and almost 42,000 signatures were submitted, so it is very likely to qualify for the ballot.
The initiative would not allow anyone to run for Congress if he or she were to attain the age of 81 during the term of office. If the voters pass it, it would probably be held invalid under the 1995 Supreme Court decision that says that neither states nor Congress can add to the constitutional qualifications for Congress that are contained in Article One.
The initiative sponsors understand that, but hope that a new court case could persuade the U.S. Supreme Court to reverse its 1995 decision. The decision had been 5-4 and the Court membership has changed since 1995.
