There's no risk that the Sandwich Town Charter will ever be confused with the United States Constitution (and not just because one is stored in a bomb-proof, climate controlled vault deep in the basement of the National Archives while the other is stored in a manilla folder in the bottom drawer of Bud Dunham's desk!), but the principal is the same -- it lays out the framework for the operation of government
Not every Town has a charter -- which can lead to some "interesting" governmental issues. For example, the Sandwich Charter prohibits Selectmen from holding any other town office or town employment while a member of the Board. In the Town of Carver, which has no charter, two of the five Selectmen are also Town employees. That must make for interesting budget discussions.
One of the requirements of the Charter is that the Selectmen appoint a Charter Review Committee at least every 5 years to advise them on potential Charter revisions. It also allows for the Charter to be amended by Town Meeting with the approval of the State Legislature. It does not, however, specifically require that the BOS actually present the Charter Committee's recommendations to Town Meeting. This discrepancy resulted in a minor political dust-up during the last round of Charter review discussions.
Last week's BOS agenda includes applicants' qualifications. The current pool of Charter Review Committee applicants looks pretty good -- a wide variety of professional backgrounds, most of whom have the reputation for doing their homework and playing well with others. This would not be a good venue for random retaliation, excessive venom, or uninformed interrogations (unfortunately, that's what Town Meeting has become!).
