In 2016, the National Transportation Safety Board (NTSB) investigated a helicopter crash, joined by representatives from the helicopter’s operator and its manufacturers. These nongovernmental parties helped shape the NTSB’s conclusions, which was standard agency practice. Tony Jobe, a lawyer for the crash victim’s family, sought communications regarding these co-investigators’ input through a Freedom of Information Act (FOIA) request.

Although FOIA generally requires government transparency, the law contains multiple exemptions from disclosure, including deliberative communications that are “intra‐​agency.” In denying Mr. Jobe’s request, the NTSB claimed that this “intra‐​agency” exemption extends to its co-investigators. On its face, the agency’s reading of FOIA makes no sense—a private party with an obvious conflict of interest cannot be considered “intra‐​agency.” More broadly, this is the latest attempt by the government to evade accountability under disclosure laws.

Mr. Jobe brought a legal challenge against the NTSB’s purported “consultant corollary” to FOIA’s exemptions, but a federal district court upheld the government’s self-serving interpretation. Mr. Jobe then appealed to the Fifth Circuit, where a three‐​judge panel affirmed the lower court. Now, Mr. Jobe seeks Supreme Court review. Building on our prior work in a companion case, the Cato Institute today filed a brief in support of the petitioner. We urge the Court to take this case and close the “consultant corollary” loophole through FOIA.
