Freedom of peaceful assembly, sometimes used interchangeably with the freedom of association, is the individual right or ability of people to come together and collectively express, promote, pursue, and defend their collective or shared ideas. The right to freedom of association is recognized as a human right, a political right and a civil liberty.
The terms freedom of assembly and freedom of association may be used to distinguish between the freedom to assemble in public places and the freedom to join an association. Freedom of assembly is often used in the context of the right to protest, while freedom of association is used in the context of labor rights and in the Constitution of the United States is interpreted to mean both the freedom to assemble and the freedom to join an association.
In the United States the right to petition is enumerated in the First Amendment to the United States Constitution, which specifically prohibits Congress from abridging "the right of the people peaceably to assemble, and to petition the Government for a redress of grievances".
Although often overlooked in favor of other more famous freedoms, and sometimes taken for granted, many other civil liberties are enforceable against the government only by exercising this basic right.
According to the Congressional Research Service, since the Constitution was written,
the right of petition has expanded. It is no longer confined to demands for “a redress of grievances,” in any accurate meaning of these words, but comprehends demands for an exercise by the government of its powers in furtherance of the interest and prosperity of the petitioners and of their views on politically contentious matters. The right extends to the "approach of citizens or groups of them to administrative agencies (which are both creatures of the legislature, and arms of the executive) and to courts, the third branch of Government. Certainly the right to petition extends to all departments of the Government. The right of access to the courts is indeed but one aspect of the right of petition."
