New South Wales Consolidated Acts(cf Traffic Act, s
17C)
If, in any proceedings in which evidence is permitted to be given of the
results of an analysis, undertaken for the purposes of this Act, of a sample
of a person’s blood or urine, evidence is given by a certificate under this
Act to the effect that alcohol or another specified drug was found by the
analysis to be present in the sample in a concentration not less than a
specified concentration:
(a) the certificate is to be treated as though it stated that the concentration of alcohol or of the other drug concerned was determined by the analysis to be present in the specified minimum concentration, and
(b) the evidence given by the certificate is not open to challenge on the basis that the analysis, merely because it purports to determine a concentration in terms of a minimum, does not meet the requirements of this Act.
