California has already announced that it will sue to maintain its waiver, charging that the Senate had no authority to overturn it. But the Senate operates largely on precedent, and now that the parliamentarian has been disregarded on this point, virtually any action the executive branch takes could be construed as a rule, and therefore subject to fast-track congressional review.
For this reason, Democrats could subject the Senate to time-consuming resolution votes repeatedly, to such a degree that the Senate would not have time to do anything else for the rest of this session of Congress. In other words, Democrats could respond to the waiver vote by paralyzing the Senate, and stopping the giant Trump tax bill from ever reaching the floor.
Georgia State University assistant professor and former House Oversight Committee staffer Todd Phillips laid this out in a Prospect piece earlier this month. Any 30 senators can force a CRA resolution onto the floor, with a required ten hours of debate time. These resolutions would need the president’s signature, and nearly all of them wouldn’t even get the Republican votes necessary to pass the Senate. But according to Senate procedure, they have to be dealt with if enough senators force them onto the floor. They must be debated and voted upon ahead of other Senate business if brought up for consideration. This means that Democrats can tie up the Senate floor for upwards of ten hours with any single CRA resolution.
