Why a 2011 ABA ethics recommendation still shows up in modern technology discussions
In 2011, the ABA Ethics 20/20 work addressed how lawyers’ growing use of electronic tools changes the confidentiality landscape. The working group described confidentiality-related concerns that arise from lawyers’ increasing transmission and storage of electronic information, including cloud computing services accessed over the Internet (such as online data storage and internet-based email).
What “client confidentiality” means in the ethics rules context
In the professional responsibility (ethics) setting, client confidentiality appears as a duty not to reveal information relating to the representation. ABA Model Rule 1.6 says a lawyer “shall not reveal information relating to the representation of a client” unless informed consent applies, disclosure is impliedly authorized to carry out the representation, or disclosure is permitted by the rule’s exceptions (ABA Model Rule 1.6).
The specific structure of ABA Model Rule 1.6 and where technology pressure points fit
ABA Model Rule 1.6 works in two connected ways. First, it generally restricts when a lawyer may reveal information, with enumerated circumstances where disclosure may be permitted “to the extent” the lawyer reasonably believes disclosure is necessary for limited purposes. Second, it sets a prevention obligation by requiring “reasonable efforts” to prevent inadvertent or unauthorized disclosure and unauthorized access to information relating to the representation (ABA Model Rule 1.6).
Competence in a technology environment connects to confidentiality duties
Technology questions connect to confidentiality because ethics rules also treat it as part of competence. ABA Model Rule 1.1’s comment describes competence as including keeping abreast of changes in the law and its practice, including “the benefits and risks associated with relevant technology,” and it also emphasizes continuing education (ABA Rule 1.1 competence comment). Discussions of technology privacy often show up alongside this competence baseline, including in technology privacy concerns background.
What the June 29, 2011 initial draft proposal targeted
On June 29, 2011, the ABA Commission on Ethics 20/20 issued an initial draft proposal that called for adopting proposed amendments to ABA Model Rules 1.18, 7.2, and 7.3 (ABA Commission on Ethics 20/20 initial draft proposal). In the Commission’s technology-focused package, Rule 1.18’s “prospective client” provisions address how information connected to client-development communications fits inside the broader confidentiality and related obligations in the Model Rules.
“Prospective client” and the use or disclosure limits in proposed Rule 1.18
The proposed amendments described in the June 29, 2011 initial draft proposal define a “prospective client” as a person who communicates with a lawyer about the possibility of forming a client-lawyer relationship and has a reasonable expectation that the lawyer is willing to consider forming the relationship (ABA Commission on Ethics 20/20 initial draft proposal). The proposal also addresses situations where no client-lawyer relationship ensues, stating that a lawyer who learned information from a prospective client shall not use or reveal that information except as Rule 1.9 would permit (ABA Commission on Ethics 20/20 initial draft proposal).
Disqualification related boundaries in the proposed technology package
The June 29, 2011 initial draft proposal included conditions for when representation could be permissible in disqualifying-information scenarios. The proposal describes scenarios involving informed consent confirmed in writing, and it also describes scenarios that rely on reasonable measures to avoid exposure to more disqualifying information plus screening and prompt written notice (ABA Commission on Ethics 20/20 initial draft proposal).
A concrete state example California’s Rule 1.6 confidentiality exception
Because state regulators enforce lawyer conduct through professional responsibility rules that may vary, state-specific confidentiality rules matter. California’s Rule 1.6 is approved effective November 1, 2018 and is tied to Business and Professions Code section 6068(e)(1). The California framework also includes a narrow disclosure exception tied to preventing a criminal act likely to result in death or substantial bodily harm (California Rule 1.6).
Ethics confidentiality vs courtroom evidentiary privilege in federal court
A common confusion treats ethics confidentiality and attorney-client privilege as the same thing. They overlap in subject matter but operate in different legal systems.
Federal evidentiary privilege rules govern what a court may require or allow in litigation. Federal Rule of Evidence 501 states that the common law governs claims of privilege as interpreted by U.S. courts, unless the Constitution, a federal statute, or rules prescribed by the Supreme Court provide otherwise. It also states that in a civil case, state law governs privilege when state law supplies the rule of decision (Federal Rules of Evidence). Federal Rule of Evidence 502 addresses waiver and inadvertent disclosures, including situations where disclosure is inadvertent and reasonable steps to prevent disclosure were taken and reasonable steps were promptly taken to rectify (Federal Rules of Evidence).
Comparison table ethics confidentiality and federal evidentiary privilege
| Topic | Ethics confidentiality (lawyer professional responsibility) | Court evidentiary privilege (federal court) |
|---|---|---|
| Primary rule source | ABA Model Rule 1.6 and state analogs (for example, California Rule 1.6) | Federal Rule of Evidence 501 (and related rules such as 502 for waiver/inadvertent disclosure) |
| General concept | Restricts a lawyer’s revealing of information relating to the representation unless an exception applies; requires reasonable efforts to prevent inadvertent or unauthorized disclosure/access (ABA Model Rule 1.6) | Governs claims of privilege in proceedings, including when privilege is determined under federal common-law principles and when state-law privilege rules apply in certain civil cases (Federal Rules of Evidence) |
| Technology-stress link described by Ethics 20/20 | Focused on confidentiality-related concerns arising from lawyers’ increasing transmission and storage of electronic information, including cloud computing | Not framed as a technology rule; it is framed as an evidentiary privilege framework, with waiver and inadvertence rules addressing how disclosure affects privilege claims (Federal Rules of Evidence) |
| Exception mechanics | Model Rule 1.6 lists limited circumstances where disclosure may be permitted and also includes prevention duties for inadvertent/unauthorized access (ABA Model Rule 1.6) | Privilege scope and waiver/inadvertence are handled under Rule 501/502 frameworks (Federal Rules of Evidence) |
Reading the recommendation without overextending it
The June 29, 2011 initial draft proposal reflects an Ethics 20/20 recommendation package built around proposed amendments to multiple ABA Model Rules, including Rule 1.18’s “prospective client” framework. The proposal’s Rule 1.18 concepts work inside the broader Model Rules approach that includes confidentiality duties in Rule 1.6 and competence expectations reflected in Rule 1.1 (ABA Commission on Ethics 20/20 initial draft proposal; ABA Model Rule 1.6; ABA Rule 1.1 competence comment).
