How do judicial techniques enable courts to have a very effective impact on actual national policy while avoiding making binding decisions? Previous academic studies have focused mostly on the controversial capacity (and willingness) of courts to intervene in a country’s policy through statutory interpretation or authoritative decisions. We show that by refraining from sweeping landmark decisions, courts can have a latent but substantial impact on actual national policy through technical and procedural measures. The case study here is the Israeli immigration policy toward a large group of Palestinian litigants (916 petitions) who claim to be neglected security-related collaborators.
