In the United States v. Brown case of 1906, the Supreme Court ruled on a matter involving land rights and mining claims in Alaska. The defendant, Mr. Brown, had staked several mining claims in an area that was later designated as part of a national forest reserve by President McKinley's proclamation under the Forest Reserve Act of 1891. When he attempted to patent his claims after this designation took effect, his application was denied by local land officials who argued that mineral lands were not subject to entry within forest reserves unless explicitly allowed by statute or presidential proclamation. The Supreme Court disagreed with this interpretation and sided with Mr. Brown. They held that while it is true that public lands can be withdrawn from private settlement, sale or location under general laws through executive order for specific purposes like creating national forests; such withdrawals do not necessarily exclude these areas from exploration and purchase for valuable minerals found therein unless expressly stated otherwise. Therefore, since there was no explicit prohibition against locating mining claims within forest reserves either in the act itself or President McKinley's proclamation establishing said reserve; Mr.Brown’s claim could proceed despite being located inside a National Forest Reserve.

The dissenting opinion in the United States v. Brown case of 1906 argued that the majority's decision to uphold a conviction under an anti-anarchy law was incorrect and violated First Amendment rights. The dissent believed that this interpretation of the law could potentially criminalize any form of political protest or criticism against government policies, thereby infringing upon free speech rights. They also expressed concern about how such laws might be used selectively against certain groups or individuals based on their political beliefs, rather than being applied equally to all citizens as required by due process principles. Furthermore, they disagreed with the majority's view that promoting violent overthrow of government is not protected speech; instead arguing for a more nuanced understanding where advocating general ideas should not be equated with inciting specific illegal actions.
