EXPLANATORY NOTE
(This note is not part of the Regulations)
These Regulations bring into force specified provisions of the Border Security, Asylum and
Immigration Act 2025 (c. 31) (“the Act”) on 5th March 2026. They are the third commencement
regulations made under the Act. Certain provisions were brought into force automatically on Royal
Assent by virtue of section 65(3). Other provisions were brought into force automatically on 2nd
February 2026 (two months after Royal Assent) by virtue of section 65(4).
Section 44(1) to (13) and (17) of the Act was commenced by section 65(3). Those provisions
permit the Secretary of State to detain a person (“P”) when they are considering whether to make a
deportation order in respect of P, or when the Secretary of State has decided to make a deportation
order pending the making of that order.
Section 44(14) to (16), the remaining subsections in section 44, amend section 51 of the Immigration
Act 2016 (c. 19) (search for nationality documents by detainee custody officers etc.) so that detainee
custody officers can require P to hand over relevant nationality documents, or so that P can be
searched for such documents (which may then be seized and retained).
