With regard to the breadth of the regulations, the court wrote (slip op. at 25; citations omitted):
The NPS regulations target much more than necessary. If a Girl Scouts leader musters her scouts onto a pavilion in a “free speech area” of Glacier National Park and proceeds to lecture them about the effects of global warming, she will have conducted both a “meeting” and a “gathering”(perhaps also an “assembly”) for which a permit would have been required. An elementary school teacher who leads eight students on an excursion to the Canyon de Chelly National Monument and, within a “free speech area,” shows off her best imitation of a traditional Navajo dance presumably has hosted an unlawful “demonstration.” If a believer in Creationism visits the Hagerman Fossil Beds National Monument and, within a “free speech area,” quietly hands out literature disputing the theory of evolution, he is guilty of “distribut[ing] . . . printed matter” without a permit. Under a plain reading of the NPS regulations, all of this speech is banned unless a permit is first acquired, even though none of it remotely threatens any of the government’s interests.
