May a former Connecticut in-house lawyer represent current or former employees against the former employer in factually distinct employment matters?

Short answer Yes on the stated facts. General knowledge of company policies and practices did not make the matters substantially related, but the lawyer may not use or reveal specific former-client information and must assess any resulting material limitation.

Plain-English summary

The requesting lawyer served as in-house counsel for an insurance company from 2002 to 2019 and handled employee-related legal issues. After leaving, the lawyer represented twelve current and former employees on similar types of issues, but none involved a problem on which the lawyer had worked before departure. The company objected based on the lawyer's broad knowledge of its personnel, procedures, and dispute-resolution strategies.

The Committee found that the old and new matters were related only at a high level of generality, not the same or substantially related under Rule 1.9(a). The rule commentary distinguishes general knowledge of an organizational client's policies and practices, which ordinarily does not preclude later representation, from specific confidential facts relevant to the new matter, which ordinarily do.

Rule 1.9(c) applies even when the matters are not substantially related. The lawyer may not use information from the former representation to the company's disadvantage or reveal that information unless the Rules permit it or the information has become generally known. The Committee cautioned that specific confidential information from the former job could be tailored to one of the employee matters and could not be used, including in cross-examination.

If Rule 1.9(c) prevents the lawyer from using information needed for a current client, the lawyer must also consider Rule 1.7(a)(2). The inability to use the information may materially limit the current representation and require withdrawal. With that caveat, the Committee concluded that the described employee representations did not violate the lawyer's duty to the former employer-client.

In practice

Under this opinion, handling a recurring type of employment problem for a former organizational client does not preclude later work on a factually distinct problem of that type. The analysis turns on the factual relationship between the old and new matters and on whether the lawyer possesses specific protected information relevant to the new representation.

The opinion treats Rule 1.9(c) as a continuing restriction independent of substantial relatedness. If that restriction prevents effective use of information for the current client, Rule 1.7(a)(2)'s material-limitation analysis also applies.

Common questions

Q: Does broad knowledge of a former employer's policies and strategies create a Rule 1.9(a) conflict?

A: Not by itself. The Committee treated that knowledge as general organizational information and found the employee matters were not the same as or substantially related to the lawyer's prior work.

Q: May a former in-house lawyer handle the same type of issue against the former employer?

A: The opinion says a lawyer who recurrently handled a type of problem is not precluded from representing another client in a factually distinct problem of that type, subject to the former-client information restrictions.

Q: What information remains protected under Rule 1.9(c)?

A: Information relating to the former representation may not be used to the former client's disadvantage or revealed unless the Rules permit it or the information has become generally known.

Q: Can the lawyer use specific former-client information to cross-examine a company witness?

A: No. The opinion identifies use of specific confidential information in cross-examination as conduct that would violate Rule 1.9(c).

Q: When does Rule 1.7(a)(2) enter the analysis?

A: If Rule 1.9(c) prevents the lawyer from using information needed for the current representation, the lawyer must consider whether that restriction materially limits the work and requires withdrawal.

Q: Did the passage of five years waive any conflict?

A: No. The opinion states that passage of time does not itself waive a conflict, while noting that the lawyer's knowledge of internal processes and strategies was likely more specific shortly after departure.

Background and rules framework

Rule 1.9(a) bars representation adverse to a former client in the same or a substantially related matter without written informed consent. The Committee used the official commentary's distinction between general knowledge of an organization's practices and specific facts that could materially advance the new client's position.

Rule 1.9(c) separately prohibits use or revelation of protected information from a former representation. The Committee explained that this restriction can apply without substantial relatedness and can create a current-client material limitation under Rule 1.7(a)(2).
