John’s appeal is online. Section [10] of the decision discussion describes being subject to a law he cannot have access to. The judge saw it but could not discuss it in court, with the plaintiff (John Gilmore) or even his lawyer. Also the orders (law) are agreed by the court to be arbitrary, changing day by day and being arbitrarily different between airports. But since the Airport personnel knew them tht was good enough for the court.
And though the discussion mentioned that he could take a bus or walk, the conclusion, [21], said that his rights were not violated at all, both the bus precedent and the legality of being subject to unknown law. The brief Wikipedia page mentions only the former, though the latter was the primary factor of the complaint.
