Our Milpitas city code, in introducing the need for campaign contribution limits declares;

In order to diminish improper influence, whether real or perceived, and the appearance of impropriety, the City Council finds that it is necessary to place limits on the amount of money that may be contributed to a candidate for elected public office in the City of Milpitas.

It then goes on to limit campaign contributions to $350 per person or corporation.

Question: Does anyone know when this city code was introduced? When did this take effect? Was there "improper influence" happening at the time?
