The ABA Standing Committee on Ethics and Professional Responsibility just released a new Formal Opinion (Number 509). The title is Disqualification to Prevent the Misuse Use of “Confidential Government Information” and the summary reads as follows:
Model Rule of Professional Conduct 1.11(c) protects a person from the misuse of certain information about the person that the government used its authority to acquire. The confidential information protected by Rule 1.11(c) is defined by the Rule as information obtained under government authority about a person which the government is prohibited from disclosing to the public or has a legal privilege not to disclose and is not otherwise available to the public. The Rule provides that a lawyer who acquired the information while serving as a government officer or employee is disqualified from representing a “private client” whose interests are adverse to prevent the confidential government information from being used to the material disadvantage of that person. The Rule applies regardless of whether the lawyer seeking to represent the private client has left government employ or office or maintains a private law practice (e.g., a part-time practice) while still in government employ or office. The Rule applies to a lawyer representing a “private client,” meaning a client whom the lawyer represents in private practice, regardless of whether the client is a public entity or private individual or entity.
For now you can access (and download) the opinion here. After some time, it will be archived and available to members only, so go get it now.
