265.Section 105 makes provision similar to paragraph 1(1) of Schedule 4 to the 1999 Act, concerning regulations governing the service of appealable decisions. Regulations may be made requiring written notice to be given of an immigration decision within the terms of section 82. When the decision is appealable the notice must declare the right of appeal and give details of how it may be exercised. Subsection (3) enables the Notices Regulations to make provision for service of the notice, including presumptions - this might include, for example, provision for service where a person has absconded and no address is known.
