(1) A coroner who is not the chief coroner but to whom a finding or death is reported under section 15(2)(b) must report it to the chief coroner as soon as practicable.
(2) As soon as practicable after a finding or death is reported to him or her under section 15(2)(b) or subsection (1) of this section, the chief coroner must—
(a) designate another coroner under section 133 as the designated coroner for the death concerned; and
(b) report that death to that coroner.
(3) However, if the designated coroner referred to in section 15(2)(a) has, since the report under section 15(2)(b), become available, then instead of acting under subsection (2) of this section the chief coroner may cause the death concerned to be reported under section 15(2)(a) to that designated coroner.
