54—Subsequent procedure where insufficient material obtained
(1) If
forensic material obtained as a result of a suspects procedure or an
offenders procedure proves to be insufficient—
(a) in
the case of an intrusive forensic procedure authorised by order under Part 2
Division 2—that procedure may be carried out again if a new order
authorising the procedure is made; or
(b) in
any other case—that procedure may be carried out again without any
further authorisation under this Act.
(2) Without limiting
subsection (1), forensic material may prove to be insufficient if the
material has become unavailable or insufficient for the purpose of enabling
information, or information of a particular description, to be obtained by
means of analysis of the material, as a consequence of—
(a) the
loss, destruction or contamination of the whole or any part of the material;
or
(b) any
damage to the whole or a part of the material; or
(c) the
use of the whole or a part of the material for an analysis which produced no
results or which produced results some or all of which must be regarded, in
the circumstances, as unreliable.
