204.Paragraph 19 enables any NCA officer, designated with the powers of an immigration officer, to exercise all the powers of an immigration officer. The exercise of immigration powers is subject to any limitations in the designation.
205.Paragraph 20 provides that where an enactment enables a warrant to be issued which authorises an immigration officer to exercise any power of an immigration officer, an NCA officer designated with immigration powers is to be treated as an immigration officer for the purposes of enabling them to exercise those powers.
