What about since the Founding Era?
In 1794, Albert Gallatin of Pennsylvania was excluded because he had not met the requirement in Article I, Section 2 of the Constitution regarding citizenship duration. In 1807, John Smith of Ohio was refused to be seated due to allegations of aiding Aaron Burr in his alleged treasonous activities – of which were later dismissed. During the late 1800s there were dozens of disputed elections which led to delays, but none of them for purely political reasons or the argument that the House was not in full session.
A part of the problem is refusing to seat Grijalva actually accomplishes nothing. She can’t vote until they are in full session, anyway. But it does keep her from being able to get her congressional things in order, i.e. staffing, getting into her office, and so forth.
Yes, technically the House controls its own proceedings, and yes the courts have no business dictating to either House of Congress how to handle their own proceedings (which gets us back to that “political question” argument). But, the truth is that, as much as I respect Speaker Johnson and the difficult position he faces during a government shutdown, as stated earlier I can find no historical defense for withholding the oath from a duly elected, certified member of the United States House of Representatives. From the Founding era through the early Republic, every historical precedent shows that once credentials are verified and the election uncontested, the House has a duty to seat the member immediately. The Founders did not design a Congress where political timing or convenience could override the people’s right to representation in the House of Representatives. Yes, technically from a constitutional point of view Johnson “can” refuse to administer the oath to Grijalva at this junction, but that doesn’t mean he “should.”
Even if Johnson’s intention is procedural, the result is that the voters of Arizona’s 7th District are, for now, voiceless in the people’s chamber. That should trouble all of us who believe in constitutional fidelity over party expedience. In the end, while the lawsuit against Johnson should be dismissed, and he should have seated Adelita Grijalva in the first place, I have a feeling this situation won’t be over until the Democrats give in on the government shutdown.
