"We the people" can amend our Constitution — our basic framework of civil rights and self-government — but we cannot rescind a personnel policy decision made decades ago and leave the civil service system. The voters of a municipality can choose to place their public employees into the civil service system. But once that decision is made, the state statute mandates that future generations of municipal citizens are bound by it.
In 1908, New Jersey became the sixth state to establish a Civil Service Commission, and today there are 194 municipalities in the system. According to the commission, "from the very beginning, the civil service law mandated that appointments to and promotions in the civil service of this state, and — from the time of its adoption by any municipality of this state — shall be made only according to merit and fitness, to be ascertained, as far as practicable, by examinations, which as far as practicable shall be competitive."
