Depositions are legal proceedings which are not typically officiated by a court officer. During such affairs attorneys can behave quite badly. Such behavior can range from simple rudeness to conduct that borders on criminal conduct such as threats of bodily harm or emotional charges to go outside and handle the matter like a man. Needless to say, you don’t want to be that guy. Only the trial court can legally terminate a deposition for abusive conduct by an attorney. Rule 30(d)(3) of the Federal Rules of Civil Procedure provides that a party may move to terminate or limit a deposition “on the ground that it is being conducted in bad faith or in a manner that unreasonably annoys, embarrasses or oppresses the deponent or party.” If the deposition is terminated you must immediately seek the trial court’s assistance and approval.

This not a course to chart unless it is justified. You and you client can be subject to sanctions and even disciplinary action for improperly terminating a deposition. See Rule of Professional Conduct 3.4. If you guess wrong and do not terminate the deposition properly, you can be responsible for paying the other party’s attorney fees. Smith v. Logansport School Corp., 139 F.R.D. 637 (N.D. Ind. 1991). Here is a famous example of things going south during a deposition courtesy of YouTube:

So be ready if abusive behavior occurs during a deposition. Act quickly and wisely… and remember don’t be that guy.
