35 In my opinion the same may be said of the process envisaged by s 13(1). The formal inquiry process is not to be held before, but is by the section required to be held after, it appears to the Board that a medical practitioner may be brought within any one or more of par (a) - par (e) in circumstances which may, in the first four cases, render the medical practitioner liable to a punishment for which s 13(3) provides, which may lead to a coercive requirement under subs (4) or, which may in a case which may fall within subs (1)(e) lead to the coercive processes provided by subs (6f) - subs (6h) inclusive. The obvious purpose at that point is merely to filter out trivial matters, matters without merit, or matters which do not in the public interest justify the holding of an inquiry which, by subs (6),must be upon notice to the medical practitioner, an inquiry in which he or she is entitled to participate, an inquiry in which under subs (6c) he or she is entitled to be represented, and an inquiry the costs of which under subs (6i) he or she may be ordered by the Board to pay. The formation of the opinion, in short, is an administrative filtering process before the practitioner may be required to become involved in an inquiry.
