As we come close - again - to the debt ceiling, questions are being raised - again - about whether the debt ceiling is constitutional. Can Congress - after it has authorized spending - refuse to provide those funds?
Here's an argument that they cannot, and that doing so violates the 14th Amendment, but the issue gets complicated:
Section 4 of the Fourteenth Amendment provides that "the validity of the public debt of the United States, authorized by law, including debts incurred for payment of pensions and bounties for services in suppressing insurrection or rebellion, shall not be questioned." Its purpose was to prevent Southern Congressmen and Senators from trying to hold payment of the nation's debts hostage in order to get their way on Reconstruction policies. The point of Section 4 was to put this sort of hostage-taking beyond ordinary politics. The framers of the 14th amendment did not want future politicians to threaten to destroy the country's finances by refusing to pay the country's debts in order to win political concessions from their opponents. After all, once politicians did so successfully, they would try it over and over again and it would become a normal feature of politics. That is precisely what we are seeing now.
If Congressional Republicans are threatening to let the nation to default on its debts if Obama doesn't agree to their demands, they are violating the Constitution. And the president should call them out for such an outrageous demand. But does that mean that the president can raise the debt ceiling himself to remedy the violation?
Not so fast. Article I, section 8 of the Constitution gives Congress, not the president, the authority to borrow on the credit of the United States. Even so, under section 4 of the Fourteenth Amendment the president has an independent constitutional obligation not to allow the validity of the debt of the United States to be put into question. That means, at the very least, that the president must make sure that interest payments continue on existing federal bonds and similar obligations. He must assure bondholders that they will continue to get paid even after the debt ceiling is reached.
If the president follows his constitutional obligations, then some government operations will not get funded because payments to the bondholders must come first. That means a partial government shutdown, with more and more of the government closed as the president continues to pay the bondholders.
