Background
Munger Hortifrut North America, LLC (Munger), a Bakersfield-area agricultural company, was embroiled in ongoing litigation with Dan Drake Enterprises, LLC (Dan Drake) when an associate attorney, Lisa Horton, moved from Munger’s law firm — Sagaser, Watkins & Wieland — to Dan Drake’s firm, Borton Petrini. Horton had billed 21.3 hours on the Munger case, including defending and taking depositions in Bakersfield. She did not tell Borton Petrini about the conflict during her interview.
Borton Petrini hired Horton to work in its Fresno office on family law and estate planning, entirely separate from the Bakersfield litigation team representing Dan Drake. Within four days of Horton starting, Munger’s counsel alerted Borton Petrini to the conflict. Borton Petrini immediately implemented an ethical screen — blocking communications between Horton and the Bakersfield team, restricting file access, and physically separating the offices — then fired Horton about ten days after she started.
Munger moved to disqualify Borton Petrini from representing Dan Drake anyway. The trial court denied the motion, finding that no confidential information had actually been shared. Munger appealed, arguing that once a conclusive presumption of shared confidences arises from a lateral hire, disqualification is automatic regardless of whether the firm fires the conflicted attorney.
The Court’s Holding
The Fifth District Court of Appeal affirmed, holding that the 2018 California Rules of Professional Conduct — specifically Rule 1.10 — govern this situation and provide the dispositive analysis. Under Rule 1.10(b), once a conflicted attorney has been disassociated from the firm, the firm may continue representing a client adverse to that attorney’s former client unless (1) the matter is the same or substantially related, and (2) any remaining lawyer holds material, confidential information derived from the prior representation. Condition (1) was undisputed — this was the same litigation. But the trial court found condition (2) was not met: no Borton Petrini attorney other than Horton had received any confidential information about the Munger case.
The court rejected Munger’s argument that an irrebuttable presumption of knowledge-sharing should doom Borton Petrini regardless of what actually happened. That stronger rule — mandatory disqualification even after the lateral hire departs — applies under Rule 1.10(a) when the conflicted attorney stays at the firm and did not substantially participate in the matter. Where, as here, the attorney leaves, Rule 1.10(b) applies, and the firm can continue if no remaining attorney holds the client’s confidences. The court also found that declarations from Stump, Horton, and others were not merely self-serving: they documented the specific measures taken, the physical and digital barriers erected, and confirmation that no substantive communications about Munger occurred.
Key Takeaways
- Under California Rule 1.10(b), a firm that fires a conflicted lateral hire avoids disqualification if the court finds no remaining attorney at the firm possesses material, confidential information from the former client’s prior representation.
- The stricter rule — mandatory imputed disqualification regardless of knowledge transfer — applies when the conflicted attorney stays at the firm (Rule 1.10(a)); it does not apply once the attorney is gone.
- An ethical screen implemented before or immediately after a conflict is discovered strengthens a firm’s position, but it is not strictly required once the conflicted lawyer is disassociated — what matters under Rule 1.10(b) is whether remaining lawyers actually hold confidential information.
- Declarations detailing the measures taken, the physical separation, and the absence of substantive communications can constitute sufficient evidence to defeat a disqualification motion even when they come from the firm’s own employees and lawyers.
- Firms hiring laterals should conduct thorough conflict checks before making the offer — the court noted that Borton Petrini’s failure to do so created the crisis, even if the outcome ultimately favored the firm.
Why It Matters
Attorney disqualification fights are disruptive and expensive — they can set litigation back months and deprive a client of chosen counsel right before trial. This case gives California litigators a clearer map of how Rule 1.10, which was overhauled in 2018, actually works in a lateral-hire conflict scenario. The key divide is whether the problematic attorney stays or goes: if she stays, the firm’s burden is heavier; if she is fired promptly and no information leaked, the firm may well survive a disqualification motion.
For in-house counsel evaluating outside-counsel switches and for law firms building conflict-check systems, the decision underscores two lessons: check conflicts before hire, and act fast (screen, investigate, terminate) if a conflict surfaces after a hire. The court’s frank attribution of blame to Borton Petrini for lax hiring procedures is a reminder that doing the right thing after the fact — while enough to avoid disqualification here — is no substitute for catching the problem before the attorney starts.
