    Absolute Rules: Things Lawyers May Not Do Under Any Circumstance

    The Rules of Professional Conduct, in most instances, are subject to interpretation, and compliance with them will depend on the lawyer's conduct. But some rules are absolute – know the difference.

    By Dean R. Dietrich

    Question

    I have heard you talk about the Rules of Professional Conduct being “rules of reason.” Are there some rules that are absolute or conduct that is absolutely prohibited?

    Answer

    For the most part, the Wisconsin Rules of Professional Conduct are rules of reason. Lawyers need to be aware of their responsibilities under the rules and should conform their conduct to what is reasonable and appropriate. The Rules of Professional Conduct also, in most instances, are subject to interpretation, and compliance with the rules will depend very much on a lawyer’s conduct.

    Dean R. DietrichDean R. Dietrich, Marquette 1977, with the law firm of Weld Riley S.C., Wausau, is immediate past president of the State Bar of Wisconsin and past chair of the State Bar Professional Ethics Committee.

    There are, however, certain types of conduct for which the rules are applied in a very rigid fashion. Some of those rules include the following.

    • You may not use the word “nonrefundable” in your fee agreement or engagement letter unless you are receiving a true retainer payment that is paid only for agreeing to represent a client and is not related to any fees for the representation. SCR 20:1.0(mm).

    • You may not put personal funds in the client trust account, other than a small amount to cover anticipated bank costs such as check costs or service fees. You may not put personal income into the client trust account to delay the accounting of those funds as income or use personal funds to pay personal expenses out of the client trust account. SCR 20:1.15.

    • You may not represent the plaintiff in a litigation matter when another attorney in your firm is representing the defendant in the same litigation. SCR 20:1.7 (b)(3).

    • You may not use client funds paid for services to be provided (an “advanced fee”) to pay for business expenses unless you follow the alternate-fee-protection requirements in all respects. SCR 20:1.0(ag), SCR 20:1.5(f).

    • You may not disclose information that you learn while representing a client for your personal benefit or for public disclosure unless the client gives informed consent to such disclosure or you need to disclose information to provide for the representation of the client. SCR 20:1.6.

    • You may not represent a client in a contingent-fee matter without a signed engagement or representation agreement. SCR 20:1.5(c).

    • You may not engage in sexual relations with a current client at any time. SCR 20:1.8(j).

    • You may not settle a litigation matter without the approval of the client. SCR 20.1.2(a).

    • You may not write stories about the representation of the client without the consent of the client. SCR 20:1.8(d).

    • You may not tell a lie to the court or misrepresent the facts or the law in statements to a judge. SCR 20:3.3(a)(1).

    Conclusion

    The specific rules above reflect an overview of the common prohibited conduct addressed in the Rules of Professional Conduct. There are other less common types of conduct that are prohibited under the rules. They are typically not subject to a reasonableness factor, while many other aspects of the rules will be applied using a reasonableness standard. Lawyers should fully understand the nature and scope of their obligations under the Wisconsin Rules of Professional Conduct.
