Written by attorneys · grounded in primary & secondary sources — see below
A prohibition applicable to lawyers that bars the use of tactics in client representation having no substantial purpose other than to embarrass, delay, or burden a third person, or the use of methods of obtaining evidence that violate the legal rights of such a person. The standard examines whether the chosen means lack any substantial connection to advancing the client's case and instead target the nonparty's privacy, reputation, or resources.

Threatened Subpoena of Roommate Messages
Nora Nash, counsel for a software company suing its former engineer, emails opposing counsel threatening to subpoena months of intimate dating-app messages from the engineer's roommate. The roommate has no employment ties to the company and no access to its code. Nora's message explicitly links the subpoena to forcing an immediate low-dollar settlement rather than to uncovering relevant facts. The roommate moves for a protective order and files a disciplinary grievance.
Deceptive Request for Mental Health Records
Nia Nkosi, defense counsel in a malpractice case, directs an investigator to call a witness's estranged spouse while falsely claiming to represent an unaffiliated clinic. The investigator obtains the witness's confidential therapy records without consent or process. Nia plans to use the records solely to impeach the witness at trial. The witness later files a grievance after learning of the deception.
Common questions
Frequently Asked
4
How does the rule distinguish between aggressive but legitimate discovery and prohibited conduct?+
The rule permits discovery tactics that rest on a good-faith factual theory connected to the claims or defenses even if they incidentally burden a third person. It prohibits tactics whose dominant aim is coercion or embarrassment rather than evidence gathering, as shown when counsel explicitly ties the threat to settlement pressure and the target has no connection to the dispute.
Supporting sources
Does the rule apply when a lawyer uses an agent to obtain evidence through misrepresentation?
Yes. A lawyer remains responsible for the conduct of investigators or other agents acting at the lawyer's direction. Using deception to bypass consent or legal protections for confidential records violates the prohibition on methods that infringe third persons' legal rights regardless of any later intended use for impeachment.
Supporting sources
What role does the breadth of a discovery request play in determining a violation?+
Overly broad requests that seek entire email lists, passwords, or months of unrelated personal messages without any targeted link to admissible evidence demonstrate the absence of a substantial legitimate purpose. Such requests support a finding of discipline when counsel's stated goal is to monitor or intimidate nonparties rather than to obtain case-specific information.
Supporting sources
Can a lawyer avoid discipline by showing that the information sought might be relevant?+
No. Relevance alone does not excuse the use of deceptive or rights-violating methods. The rule separately prohibits methods that infringe legal privacy rights even when the lawyer hopes to use the material for impeachment or other litigation purposes.
