First Amendment
Protects expression, religious liberty, publication, peaceful assembly, and the right to ask government for change — and generates more real litigation than almost any other part of the Constitution.
What It Protects
Speech
Protects expression, including unpopular or controversial views, from government restriction.
Religion
Bars government from establishing an official religion or restricting free religious exercise.
Press
Protects publication and reporting from government censorship or retaliation.
Assembly
Protects the right to gather peacefully, including protests and demonstrations.
Petition
Protects the right to ask government for change — the basis for lobbying, formal complaints, and organized advocacy.
Where the Real Boundaries Get Drawn
The text is short, but the boundaries are almost entirely defined by case law — when does student expression cross into disruption, when does political spending count as speech, when does a restriction on assembly become a real burden on the right itself.
Student speech doesn’t stop at the schoolhouse gate
The Court held that students don’t lose First Amendment protection at school, and that schools need more than discomfort or fear of controversy to suppress peaceful political expression. This remains the leading case on student speech and school authority — the standard schools still have to meet today when they try to restrict what students say or wear.
Political spending as speech
The Court held that the government may not ban independent political expenditures by corporations and unions based on speaker identity. The decision reshaped campaign finance and political spending through outside groups, and remains one of the most cited — and most contested — First Amendment rulings of the modern era.
