EPIC and 25 organizations have urged Congress to hold a hearing on TSA's decision to end the opt-out for airport body scanners. Dozens of organizations petitioned the DHS secretary in 2010 to solicit public comments on the original program. In EPIC v. DHS the lawsuit that followed, the D.C. Circuit ruled that TSA violated federal law when it installed body scanners in airports without public comment. The agency said at the time that the body scanner program was optional. The Court also concluded because "any passenger may opt-out of AIT screening in favor of a patdown" there was no violation of the Fourth Amendment.
