ACLU's Dale Ho objected that it's an "ambush" + govt denied discovery on it.
Judge Furman postponed ruling.
"What's the point of this particular line of inquiry?" he asks, noting it's undisputed that citizenship question causes a decline in self-response rate.
This is why the plaintiffs called him as an adverse witness.
* he and the Census Bureau recommended against the citizenship question.
* adding it would be expensive and result in worse data.
* non-response follow up (NRFU) could mitigate it.
Judge Furman says that he's "preliminarily inclined" to strike testimony that the Census Bureau will conduct randomized control testing + that the govt's failure to disclose it before now seems to have been a "blatant violation of the govt's discovery obligations."
* be expensive
* lower self-reporting
* yield lower-quality data
But he stops short of one key finding.
