Article 24 of the 1975 Constitution stated: "The People's Republic of Angola guarantees individual freedoms, namely the inviolability of the home and the privacy of correspondence, subject to the limits expressly provided for by law." Today, privacy rights are protected in Articles 32 (personal and family life), 33 (home), and 34 (correspondence and communication) of the 2010 constitution.
