““There is no remedy in the federal statutes governing the census and apportionment to correct this problem. The scope of this problem was unusually high, and the Census Bureau has not offered any explanation as to how this happened.”
Sure there is. It is a constitutionally mandated process. It cannot be done fraudulently or with reckless process lest it become void. This can be explored in a lawsuit and ruled on by the Supreme court.
Excellent point.
