Rule of Law:
A law firm may be disqualified from representing a client against a former client if the current matter is 'substantially related' to the prior representation, which occurs when the firm was exposed to confidential information during the prior representation that could be used against the former client in the current litigation.
Facts:
- Between 1980 and 1990, the law firm Cain Hibbard represented John and Dina Fontaine on personal and business matters.
- In 1987, Cain Hibbard assisted Dina Fontaine with the incorporation of her business, Dina’s Antiques, Inc., and provided advice on the proper maintenance of corporate formalities.
- In a 1989 letter, Cain Hibbard reminded Dina Fontaine of the necessity of maintaining corporate records to serve as a 'barrier against personal liability.'
- Shortly after, a Cain Hibbard paralegal sent Dina Fontaine backdated stockholders' resolutions for her to sign to update the corporate minute book.
- The Fontaines' business entities held an auction for a 1,500-ounce solid gold statue of Mickey Mouse, consigned by American Investment Properties, Inc. (AIP).
- During the auction, the high bidder was permitted to leave with the statue without providing payment.
- AIP assigned its interest in the statue and its legal claims to R & D Muller, Ltd., which incurred substantial costs to retrieve it.
- R & D Muller, Ltd. retained Cain Hibbard to sue the Fontaines and their businesses, seeking to pierce the corporate veil and hold the Fontaines personally liable.
Procedural Posture:
- R & D Muller, Ltd. filed suit against the Fontaines and their business entities in a Massachusetts trial court.

Issue:
Is a law firm's prior representation of a client on the topic of establishing and maintaining corporate formalities 'substantially related' to a subsequent lawsuit against that same client where a key claim is piercing the corporate veil for failure to observe those formalities, thus requiring the firm's disqualification under Mass.R.Prof.C. 1.9(a)?
Opinions:
Majority - The Court
Yes. The prior representation is substantially related to the current litigation, which requires the law firm's disqualification. Massachusetts Rule of Professional Conduct 1.9(a) prohibits a lawyer from representing a new client in a matter that is the same or substantially related to one handled for a former client if their interests are adverse. Two matters are substantially related if the lawyer was exposed to confidential information in the first representation that could be used against the former client in the second. Here, Cain Hibbard advised the Fontaines on the very subject—observing corporate formalities to prevent personal liability—that is now the basis for the plaintiff's attempt to pierce the corporate veil. This previous work necessarily exposed the firm to confidential information about the Fontaines' corporate practices, which is directly germane to the current dispute. Therefore, the matters are substantially related, and disqualification is appropriate to protect the former client's confidences.
Analysis:
This decision underscores the enduring nature of an attorney's duty of loyalty and confidentiality to former clients. It clarifies that the 'substantially related' test for conflicts of interest focuses on the subject matter of the representations and the potential for misuse of confidential information, even if significant time has passed. The ruling serves as a stark reminder to law firms that providing corporate formation and governance advice can create a future conflict that bars them from handling litigation against that same client, particularly in cases involving attempts to pierce the corporate veil. This precedent reinforces the importance of meticulous conflict-checking systems that consider the substantive nature of past work, not just the names of former clients.
