Let me pursue that in terms of other assessments. From some of the other criminal defence lawyers who've come before us, we've heard of the need to have a clearer set of regulations that would require the technician to have taken these steps every time the assessments are done, so that when the machine is not being used, it will be tested on an ongoing basis—and of the need for that to be done, if I understood correctly, by independent authorities, rather than the technicians or police officers.
Has the Bar Association done any detailed analysis of what would be required to have that regime in place, or what would be required, in effect, to meet the greater degree of certainty in the validity of the equipment?
