Note to future lawyers. Here are things you don't do in a deposition, held in an expensive foreign locale, such as Italy: coach witnesses, tell them how to answer questions, or walk out and cancel all remaining depositions without a really good reason.
Such "totally inappropriate" conduct is "deserving of sanctions."
How much in sanctions? Close to a million dollars, with attorneys' fees and expenses included. The original order, however, ordered sanctions against the plaintiffs, not their attorney. After the district court clarified via Rule 60(a), the lawyer's lawyer missed the deadline to appeal.
Lawyer gets stuck with a $1,000,000 tab. Lawyer's lawyer gets a malpractice suit.
