It is the purpose and intent of this chapter to revise and make uniform the laws of this state concerning the transaction of business by municipal officers, as defined in chapter 268, Laws of 1961, in conflict with the proper performance of their duties in the public interest; and to promote the efficiency of local government by prohibiting certain instances and areas of conflict while at the same time sanctioning, under sufficient controls, certain other instances and areas of conflict wherein the private interest of the municipal officer is deemed to be only remote, to the end that, without sacrificing necessary public responsibility and enforceability in areas of significant and clearly conflicting interests, the selection of municipal officers may be made from a wider group of responsible citizens of the communities which they are called upon to serve.
