Part 1: Espionage, sabotage and persons acting for foreign powers Powers of search etc. Schedule 6: Detention under Section 27 Part 6: Extension of detention under section 27
Part 6 provides for police and prosecutors to apply to the Courts for a warrant of further detention. Without such a warrant, a detained person must be released after 48 hours in accordance with section 28(3). Paragraph 37 provides that a warrant must state the specified period that the detained person can be further detained for, up to 7 days beginning with the time of the initial arrest or detention in accordance with section 27(3). Under paragraph 44, an application for the extension or further extension of a warrant can be made and authorised for an additional 7 days, up to a total maximum of 14 from the initial arrest or detention. Paragraph 38 provides that the application for a warrant must be made to the Court within 54 hours of the initial arrest, and the Court must dismiss the application if it considers that it would have been practical for the application to have been made during the first 48 hours of detention.
	The grounds on which the judicial authority may grant a warrant of further detention are provided for at paragraph 40 and include if it is necessary to obtain evidence by questioning the suspect, to preserve evidence and to permit the examination or analysis of evidence.
	Paragraph 41 provides for the right of the detained person to be given the opportunity to make representations to the court regarding their application and be legally represented at the hearing if requested. The court has the power to exclude the detained person or their representative from any part of the hearing under paragraph 41(3). Under paragraph 42(1) an application may be made to the court to withhold certain information on which the application is based from the detained person and their representative. The judicial authority may make such an order if any of the conditions at paragraphs 42(2) or 42(3) are satisfied, which includes that the prevention of foreign power threat activity would be made more difficult as a result of a person being alerted.
	Paragraph 45 indicates that if the reasons for which the authorisation of continued detention were made no longer apply, the person must be released immediately. References to judicial authorities who authorise detention under this Part are a reference to the formal job title and applies to the current office holder regardless of their gender.
