56—Evidence produced by processes, machines and other devices
(1) This section
applies to a document or thing—
(a) that
is produced wholly or partly by a device or process; and
(b) that
is tendered by a party to proceedings who asserts that, in producing the
document or thing, the device or process has produced a particular outcome.
(2) If a device or
process is one that, or is of a kind that, if properly used, will ordinarily
produce that outcome, it will be presumed, in the absence of evidence to the
contrary, that, in producing the document or thing on the occasion in
question, the device or process produced that outcome.
Example—
It would not be necessary to call evidence to prove that a photocopier
normally produced complete copies of documents and that it was working
properly when it was used to photocopy a particular document.
