The right to associate or assemble peacefully with any lawful object may not be restricted; but only the citizens of the Republic may do so in order to take part in the political affairs of the country. No armed meeting has the right to deliberate.
An assembly or meeting that has as its object to make a petition or present a protest for some act, to an authority, shall not be considered illegal, and may not be dissolved, if no insults are uttered against it, nor use is made of violence or threats to intimidate it or oblige it to resolve in the sense that is desired.
