A bill to revoke the citizenship of those who collaborate with terrorists will soon reach the final stages of legislation. A new study by Efrat Rahaf opposes this bill and recommends annulling the power to revoke citizenship on grounds of disloyalty to the state. The 11th clause of the Nationality Law authorizes the Minister of Interior to revoke the citizenship of a person who "has committed an act of disloyalty towards the State of Israel," and also states that citizenship shall be revoked for unlawfully visiting an enemy state. This study proposes a critical analysis of these stipulations and, among other things, discusses MK Gilad Erdan's proposal to amend the clause in order to enable increased use of these powers, which until recently were considered to be a "dead letter."
