Update (9/30/09)
I tend to focus a lot on weaknesses of ethics codes, but sometimes
ethics codes go too far. One reason for this is that they are usually
responses to scandals that are criminal in nature, that is, scandals that do not
involve conflicts of interest. Another reason is that most people don't
understand that ethics codes are really conflict of interest codes, not
codes that deal with all of an official's behavior. It's appropriate to
have aspirational provisions that go beyond conflicts of interest, as
the City Ethics Model Code has, but there are many things, such as
truthfulness and civility, that should not become the subject of legal
proceedings.
A big issue when ethics codes are being written or revised is whether
to limit their provisions to conduct directly relating to government
work, or to extend it into the official and employee's non-work life,
at least the non-work life that does not involve conflicts with government obligations.
