It is in section 16, under the heading "Examination of application: general". Maybe I misspoke. It is the chief deciding officer who makes the determination. Section 16(3) states:

(3) The Chief Deciding Officer— (a) shall, subject to paragraph (b), complete his or her examination of an application and make his or her determination, as soon as practicable, and

(b) may accord priority to the examination of an application where he or she considers that it is in the interest of fairness and efficiency to do so, having regard in particular to the personal circumstances, including the age and state of health, of the applicant.
