A lawyer shall not make a false or misleading communication about the lawyer or the lawyer's services. A communication is false or misleading if it:
(a) contains a material misrepresentation of fact or law, or omits a fact necessary to make the statement considered as a whole not materially misleading;
(b) is likely to create an unjustified expectation about the results the lawyer can achieve, or states or implies that the lawyer can achieve results by means that violate the rules of professional conduct or other law;
(c) compares the lawyer's services with other lawyers' services, unless the comparison can be factually substantiated; or
(d) contains a testimonial or endorsement.
This Rule governs all communications about a lawyer's services, including advertising permitted by Rule 7.2. Whatever means are used to make known a lawyer's services, statements about them should be truthful. The prohibition in paragraph (b) of statements that may create "unjustified expectations" would ordinarily preclude advertisements about the results obtained on behalf of a client, such as the amount of a damage award or the lawyer's record in obtaining favorable verdicts, and advertisements containing client endorsements. Such information may create the unjustified expectation that similar results can be obtained for others without reference to the specific factual and legal circumstances.
