Sounds expensive to me.
Filing a few papers in three cases, most of which were likely based on templates/pre-existing motions filed in other cases, was not that expensive for the private attorneys. Because Orly is so ... prolific ... in filing paper after corrected paper after paper, the DOJ has had to file a few more papers than the private attorneys had to file. Still, the job’s been pretty small and at least should have been inexpensive - to date - because the DOJ has only responded when required, and responded with short, concise briefs. Their most recent brief was a 2-pager - copied from their last brief (eliminating one page of argument). Pretty simple. Not expensive.
