Yes there is, the Supreme Court.
The Constitution states:
The actual Enumeration shall be made within three years after the first meeting of the Congress of the United States, and within every subsequent term of ten years, in such manner as they shall by law direct.
The right-wing will challenge any attempt to redo the Census as 2020 is the 10th year, and it specifies an “actual Enumeration” (singular).
And you know that, unless Congress acts first to expand the court and add more justices, it will side with the RWNJ lawyers are prohibit an redo of the Census,
One might argue that a revision of the Census could be done that would not be a second Census, but a correction of it, but again, without expanding the court so the RWNJ injustices on it are not in control, this woudl not pass muster either.
