Can a lawyer who serves as a part-time municipal judge represent private clients before the town council or defend a client by cross-examining police officers who appear before that judge?

Plain-English summary
A lawyer in private practice is also a part-time municipal court judge. The lawyer is asked to represent Client A before the town council in the town where the lawyer is a part-time judge, and to defend Client B in a circuit-court murder case in which the lawyer expects to cross-examine police officers who appear before the lawyer as witnesses when the lawyer sits as municipal judge. The opinion asks whether the lawyer may take each representation, and answers yes, qualified, to both.
The opinion starts with Oregon RPC 8.4(a)(4) (no conduct prejudicial to the administration of justice) and 8.4(a)(5) (no stating or implying an ability to improperly influence a government agency or official). The mere fact of representing these two clients does not indicate any violation. Under Oregon RPC 1.7(a), no conflict exists because in each matter the lawyer has only one client. On the facts there also appears to be no self-interest conflict requiring informed consent under RPC 1.7(b), though the opinion notes there could be circumstances where there is a significant risk that the representation of private clients would be materially limited by the lawyer's personal interests in the municipal-judge role, in which case the lawyer would have to comply with RPC 1.7(a)(2) and (b).
The opinion also addresses the public-official rules. Oregon RPC 1.11(d) makes a lawyer currently serving as a public officer subject to RPC 1.7 and 1.9 and bars using the public position to obtain special advantage, to influence a tribunal in favor of the lawyer or a client, or to use confidential government information for a private client; on the present facts there is no reason to believe that rule would be violated. The opinion adds in a footnote that RPC 1.12(a) (a lawyer who participated personally and substantially as a judge in a matter) does not appear to prohibit these representations on the facts.
In practice
The opinion holds that, under the Oregon rules, a part-time municipal judge in private practice is not categorically barred from representing private clients before the council or in court, and that the controlling questions are the single-client conflict analysis under RPC 1.7, the personal-interest limit under RPC 1.7(a)(2), and the public-official restrictions of RPC 1.11(d), along with the general bars in RPC 8.4(a)(4) and (5). The analysis turns on whether, in a given matter, the lawyer's judicial role creates a significant risk of materially limiting the representation or an improper use of the public office. Verify the current text of Oregon RPC 1.7, 1.11, 1.12, and 8.4 before relying on any specific point.
Common questions
Q: Can I represent private clients before a body in the same town where I am a part-time judge?
A: Qualified yes. The opinion concludes the representation is not barred outright; with one client in the matter there is no RPC 1.7(a) conflict, and on the facts no improper use of the public office.
Q: Can I cross-examine police officers who appear before me when I sit as judge?
A: Qualified yes. The opinion concludes that, on the facts given, defending the client is permissible, subject to RPC 1.7(a)(2) if circumstances create a significant risk that the lawyer's judicial-role interests would materially limit the representation.
Q: What public-official rules apply to me as a part-time judge?
A: The opinion points to RPC 1.11(d): a lawyer serving as a public officer is subject to RPC 1.7 and 1.9 and may not use the public position to gain special advantage, influence a tribunal in favor of a client, or use confidential government information for a private client.
