A newly formed group is now pushing City Hall to adopt an official code of ethics to be overseen by an appointed committee with authority to impose disciplinary action against violators. According to Pam Brandon of Citizens Planning Association — now spearheading the fledgling effort — City Hall lacks a code of ethics and has instead “a code of conduct” guiding elected officials and members of the city’s numerous advisory committees. The new code of ethics, Brandon said, would apply to city staff, as well, and would, among other things, limit gifts to no more than $50 worth in any 12-month period. Brandon said such a code would inspire confidence in City Hall and was common to many municipal operations. Two years ago, Brandon blew the whistle on a member of the Architectural Board of Review for improperly lobbying staff behind the scenes on behalf of a client. That member was fined by the Fair Political Practices Committee and resigned.
