In the case of Attorney General vs. Federal Street Meeting-House, the Supreme Court was asked to decide whether a church in Boston had violated federal law by allowing an abolitionist group to use its building for meetings and speeches. The court held that while Congress had authority over interstate commerce, it did not have power to regulate speech or assembly within a state's borders. Furthermore, they found that any attempt by Congress to do so would be unconstitutional as it would violate the First Amendment right of free speech and assembly. Ultimately, this decision established an important precedent protecting citizens' rights from government interference when engaging in peaceful activities such as public speaking and religious worship within their own states.

The dissenting opinion in the case of Attorney General vs. Federal Street Meeting-House was that Congress had no authority to pass a law prohibiting religious worship in any place within the United States. The majority opinion held that such an act would be unconstitutional, as it violated both the First Amendment and Article I, Section 8 of the Constitution which grants Congress power over all places purchased by consent of state legislatures for public use. Justice Grier argued that this decision was not only contrary to precedent but also inconsistent with other decisions made by Supreme Court justices at earlier times. He further noted that if Congress were allowed to prohibit religious worship on federal property then they could do so anywhere else as well, thus infringing upon individual rights protected under the Bill of Rights and undermining states' rights reserved under Article I, Section 10. In conclusion he stated his belief that “the right freely to assemble for lawful purposes is one which belongs equally to every citizen” and should not be infringed upon without due process or just cause.
