Should Attorney be subject to disqualification under such circumstances?Discuss

Attorney represented Client in a residential real estate transaction. At the same time, Attorney agreed to represent the defendant in a large class-action lawsuit, an alcoholic beverage maker that understated the alcohol content of its products on its labels, leading to numerous cases of inadvertent intoxication, liver damage from continuous consumption, and a few deaths from overconsumption that led to alcohol poisoning.

Client was an unnamed member of the plaintiff class in the class-action lawsuit against the alcohol producer. Attorney did not inform Client that he was representing the defendant in the class-action lawsuit or seek consent from Client or from the alcohol producer. Plaintiffs’ counsel in the class action lawsuit discovered this situation, and asked the court to disqualify Attorney from representing the defendant.
