Information Section 42: information: embarking passengers
113.Section 42 amends paragraphs 3 and 16 of Schedule 2 to the Immigration Act 1971, which currently enables an immigration officer to examine departing passengers to establish nationality and identity.
114.Subsection (2) amends paragraph 3 so as to extend the powers of examination on embarkation to cover three new kinds of information. An immigration officer will have the power to examine an embarking passenger not only for the purpose of establishing whether he is a British citizen, and if not, his identity, but also to establish whether:
	his entry to the United Kingdom was lawful;
	he has complied with any conditions of leave to enter or remain in the United Kingdom; and
	his return to the United Kingdom is prohibited or restricted.
115.Subsection 2 also amends paragraph 3 so as to enable an immigration officer to require a person to submit to further examination by giving him written notice that he must do so.
116.Subsection 3 amends paragraph 16 of Schedule 2 to the 1971 Act by introducing the power for a person to be detained under the authority of an immigration officer where he has been required to submit to further examination on embarkation.   The detention can only be for a maximum of 12 hours pending the completion of the further examination.
117.Subsection 4 is a consequential amendment to make clear that paragraph 21 of Schedule 2 to the 1971 Act, which makes provision for temporary admission, does not apply to detention of departing passengers. As detention is permitted only for a maximum of 12 hours the power to grant temporary admission is not necessary.
