The Portuguese Constitution guarantees freedom of expression, but this right is not absolute and may be limited by laws that regulate censorship. The Law on Freedom of Expression, approved by Decree-Law No. 108/2007, of April 12, establishes the rules for the exercise of this right. Censorship in Portugal is subject to the principles of necessity, proportionality, and legality. Any restriction on freedom of expression must be provided for by law and must be necessary in a democratic society.
This law protects people's right to express themselves, but the government can limit this right in certain situations. The limitation must be necessary and follow the law.
