58.This section amends paragraph 4 of Schedule 2 to the Immigration Act 1971 by deleting paragraph 4(2A), substituting paragraph 4(4) and adding a new paragraph 4(5). It makes two substantive changes. First, it brings together the provisions on detention and examination of passports and other documents produced by passengers, or found on them, while being examined under Schedule 2 and provides that the same conditions govern detention and examination for all documents. Second, it provides a new power to enable immigration officers to require passengers being examined under Schedule 2 to provide biometric information (such as fingerprints) for the purpose of ascertaining whether a passenger in question is the rightful holder of the passport or other document he produces.
