In 1960, the country’s first constitution protected the private life, home, and correspondence of each person in Article 22 (World Statesmen, “The Constitution of the Federation of Niger”). Today, the same language is seen in Article 37 of the 1999 constitution (Constitute Project, “Nigeria Constitution 1999 rev. 2011”).
