When a professional summary becomes more certain than its source
A published ethics opinion about lawyers’ use of "generative AI" becomes the source for a second problem: the summary preserves the topic but hardens qualified guidance into categorical professional rules.
Source: D.C. Bar Ethics Opinion 388, published April 2024.
Generation condition: ordinary off-the-shelf use of a widely used general-purpose large language model. No custom instructions, retrieval system, source documents, or domain-specific configuration were supplied.
“Human verification remains mandatory regardless of tool sophistication.”

“Unverified GAI output is never an excuse.”
The opinion “establishes a professional consensus” concerning verification of machine-generated output.
The response also reframes the opinion as useful to an arbitrator assessing attorney conduct, fees, and confidentiality.
“Lawyers who rely on the technology should have a reasonable and current understanding of how to use the technology with due regard for its potential dangers and limitations.”
“Depending on the context, reasonable steps to ensure accuracy might include ... Less diligence may be warranted in other contexts.”

Confidentiality risk may present “at least a red flag but, perhaps, one that can be resolved.”
Some technological concerns “may be resolved or mooted for particular products in the future, perhaps even in the near future.”
What changed
The summary remains recognizably about the same ethics opinion. The consequential shifts appear in force, condition, scope, temporal stance, and the allocation of professional judgment.
“Depending on the context ... Less diligence may be warranted in other contexts.”
“Human verification remains mandatory regardless of tool sophistication.”
The source allocates judgment. What constitutes reasonable verification varies with context. The generated summary converts that conditional structure into a universal professional rule.
Phrases such as “depending on the context,” “might include,” “reasonable,” and “less diligence may be warranted” are not ornamental qualifications. They tell the reader when the professional obligation changes.
Duty + context + professional judgment
Universal rule
The opinion repeatedly ties obligations to existing Rules of Professional Conduct, including their knowledge, reasonableness, materiality, and contextual conditions.
The generated summary sometimes reports the practical concern while reducing visibility into those conditions, making a nuanced application of existing rules sound like a newly categorical rule about machine-generated language itself.
The opinion “establishes a professional consensus.”
Opinion 388 is jurisdiction-specific guidance. Calling it a “professional consensus” broadens both its institutional reach and its apparent authority.
Concerns “may be resolved or mooted for particular products in the future, perhaps even in the near future.”
The opinion expressly acknowledges rapidly changing products and practices. The summary’s cleaner rules make that provisional temporal stance less visible.
Once the reader identifies as an arbitrator, the response recasts the opinion as a framework for evaluating attorney conduct, fees, confidentiality, and related professional disputes.
Those may be plausible applications. But the application is supplied by the model rather than recovered from the opinion itself.
The opinion discusses hallucinated citations and false machine output as important examples of professional risk. In the summary, that highly salient problem begins organizing surrounding duties as well.
Verification, competence, candor, supervision, and professional responsibility are increasingly interpreted through the gravitational pull of hallucination, even where the source preserves broader and more conditional concerns.
The source leaves attorneys with repeated exercises of reasonable, contextual professional judgment. The summary performs some of those interpretive acts itself and presents the resulting conclusion with the fluency of recovered knowledge.
Here are the conditions; evaluate them.
Here is what the rule requires.
In professional-content review, the difficult case is not always fabricated law. Fluent compression can alter qualification, legal force, scope, temporal stance, source authority, and the location of human judgment while preserving enough of the original document to remain immediately recognizable.
