As with other criminal law issues of continuity of evidence, defence lawyers will be concerned with the chain of custody of the clear liquid (or clear gas) in the (clearly identified) simulator jar (or canister of dry gas) between the point in time when the bottle that came from the lab had its seal broken and the time of use with our client, probably days later, by another qualified technician.

If the subsequent technician purports to identify the clear alcohol standard in the clear wet-bath simulator with no reference to a seal between the simulator jar and housing and with no reference to an alcohol standard log, something is very wrong.

Check to see if there is an "alcohol standard log" as in R. v. Jackson. Is there an alphanumeric seal between the simulator jar and simulator housing with recording in notes of the number? Are officers' notes complete?

The Inquiry into Pediatric Forensic Pathology in Ontario was established by the Government of Ontario under the Public Inquiries Act on April 25, 2007. The Honourable Stephen T. Goudge was appointed Commissioner. From Executive Summary, page 9:
"It follows that, although every forensic pathologist needs to be a competent
clinical pathologist, the opposite is not true. Many competent clinical pathologists
will never have an interest in forensic work and will never need to obtain the
requisite knowledge and expertise in forensic work. A forensic pathologist, how-
ever, must be trained in, and develop an aptitude for, the requirements of the legal
process. This requires an emphasis in the conduct of the post-mortem examina-
tion on identifying forensically significant findings such as injury, collecting
potentially relevant evidence, and maintaining its continuity, none of which arise
in clinical pathology"
