(a) It shall be the duty of the Attorney General or each district attorney of a superior court to whom any violation is reported by the Commissioner or his representative to cause appropriate proceedings to be instituted and prosecuted in a court of competent jurisdiction without delay. Before the Commissioner reports a violation for such prosecution, an opportunity shall be given the distributor to present his view to the Commissioner.

(b) Nothing in this chapter shall be construed as requiring the Commissioner or his representative to report for prosecution, to institute seizure proceedings, or to issue a withdrawal from distribution order as a result of minor violations of the chapter or when he believes the public interest will best be served by suitable notice or warning in writing.
