“provided more than 329,000 documents and more than 1.7 million data points, including detailed compensation information, in response to OFCCP’s 18 different data requests.” Ufff, that's a huge number.
On the one hand I agree. On the other, that's probably less data than Google collects from Android devices in Manhattan per second. Essentially, the judge has prevented the Justice Department from obtaining mineable data and made it harder for the Justice Department to provide statistical proof for a pattern of behavior (if it exists).
What I find interesting in the way this story is being headlined across media outlets is that the headlines imply that the judge has ruled regarding the merit of the case rather than as an administrative ruling regarding discovery.
