Deportation was the forced immigration of an individual as punishment for a crime.
In 2267, Spock doubted James T. Kirk' assertion that the SS Botany Bay was a penal deportation vessel, as wasting a technologically advanced ship would be an inefficient solution (TOS: "Space Seed")
In 2372, Akorem Laan suggested deportation as an appropriate penalty for Bajorans who defied a reinstated d'jarra system. (DS9: "Accession")
