We have blogged about the "company Doe" suit a couple times, including here. That's the case in which a company sued to block the inclusion of a product report in
the Consumer Product Safety Commission's publicly available,
web-accessible database about potentially dangerous products. The
district court permitted the company to litigate in secret and under the
pseudonym "Company Doe," and several advocacy groups appealed that ruling to the 4th circuit saying that the district court's secrecy policy violated common-law and constitutional rights of access to the courts. Read this report by Mike Scarcella about the appellate argument.
