The Model Rules as a Rule System
The Model Rules as a Rule System
A computational reading of actors, duties, permissions, prohibitions, knowledge standards, exceptions, consent, imputation, and jurisdictional variants.

Scope and honesty note
Jurisdiction: comparative United States professional-responsibility classroom model as of 2026-08-29. ABA Model Rules are models; jurisdictions adopt variants, and the pinned North Carolina rules are state-published examples rather than universal text. Texas uses its own disciplinary rules. Synthetic facts are classroom inputs, not legal advice. This model cannot form an attorney-client relationship, decide discipline, authorize practice, clear a conflict, waive confidentiality, move client funds, or replace regulator and licensed-attorney review. Cite, expose uncertainty, abstain, and hand off.

Begin with professional-responsibility doctrine
The ABA Model Rules are a template, not governing law by themselves. A jurisdiction's adopted text, definitions, comments, orders, ethics opinions, discipline decisions, statutes, and procedural rules determine force and meaning. Computational reading begins with actor, deontic operator, object, mental state, circumstances, exceptions, consent, documentation, imputation, and remedy. Comments guide interpretation but are not themselves rule text. A rule engine may expose a trace and unresolved inputs; it must not declare ethical compliance or authorize conduct.
Competence example
The published North Carolina rule supplies an operative duty with knowledge, skill, thoroughness, and preparation terms. Verbatim source text: “A lawyer shall not handle a legal matter that the lawyer knows or should know he or she is not competent to handle without associating with a lawyer who is competent to handle the matter. Competent representation requires the legal knowledge, skill, thoroughness, and preparation reasonably necessary for the representation.” Source: N.C. R. Prof. Conduct 1.1; https://www.ncbar.gov/for-lawyers/ethics-and-governing-rules/rules-of-professional-conduct/10-119-client-lawyer-relationship/11-competence/; official-source fixture (not neochart).
Confidentiality example
The published state rule illustrates prohibition, authorization, exception, and protective-action structure. Verbatim source text: “(a) A lawyer shall not reveal information acquired during the professional relationship with a client unless the client gives informed consent, the disclosure is impliedly authorized in order to carry out the representation or the disclosure is permitted by paragraph (b). (b) A lawyer may reveal information protected from disclosure by paragraph (a) to the extent the lawyer reasonably believes necessary: (1) to comply with the Rules of Professional Conduct, the law or court order; (2) to prevent the commission of a crime by the client; (3) to prevent reasonably certain death or bodily harm; (4) to prevent, mitigate, or rectify the consequences of a client's criminal or fraudulent act in the commission of which the lawyer's services were used; (5) to secure legal advice about the lawyer's compliance with these Rules; (6) to establish a claim or defense on behalf of the lawyer in a controversy between the lawyer and the client; to establish a defense to a criminal charge or civil claim against the lawyer based upon conduct in which the client was involved; or to respond to allegations in any proceeding concerning the lawyer's representation of the client; (7) to comply with the rules of a lawyers' or judges' assistance program approved by the North Carolina State Bar or the North Carolina Supreme Court; or (8) to detect and resolve conflicts of interest arising from the lawyer's change of employment or from changes in the composition or ownership of a firm, but only if the revealed information would not compromise the attorney-client privilege or otherwise prejudice the client. (c) A lawyer shall make reasonable efforts to prevent the inadvertent or unauthorized disclosure of, or unauthorized access to, information relating to the representation of a client. (d) The duty of confidentiality described in this Rule encompasses information received by a lawyer then acting as an agent of a lawyers' or judges' assistance program approved by the North Carolina State Bar or the North Carolina Supreme Court regarding another lawyer or judge seeking assistance or to whom assistance is being offered. For the purposes of this Rule, "client" refers to lawyers seeking assistance from lawyers' or judges' assistance programs approved by the North Carolina State Bar or the North Carolina Supreme Court.” Source: N.C.

UPL example
The published state rule illustrates jurisdiction and assistance prohibitions. Verbatim source text: “(a) A lawyer shall not practice law in a jurisdiction where doing so violates the regulation of the legal profession in that jurisdiction. (f) A lawyer shall not assist another person in the unauthorized practice of law.” Source: N.C. R. Prof. Conduct 5.5(a), (f); https://www.ncbar.gov/for-lawyers/ethics-and-governing-rules/rules-of-professional-conduct/51-57-law-firms-and-associations/55-unauthorized-practice-of-law/; official-source fixture (not neochart).
Pin the synthetic representation record
A synthetic rule corpus versions three published North Carolina duties and a product scenario involving client information, competence, software delegation, jurisdiction, disclosure, consent, screening, supervision, and escalation. Each node records whether it is operative text, comment, interpretation, or product policy.
Work the ethics application
The parser classifies competence as an affirmative duty, confidentiality and UPL provisions as prohibitions with different exceptions or scope, and comments as interpretive rather than operative. It then selects the actual adopting jurisdiction and effective version. Unknown facts remain unknown; a product policy may be stricter but cannot rewrite the governing rule.
Read the populated ethics record
The rule-system record contains jurisdiction, publisher, adoption, version, effective date, rule, paragraph, actor, operator, object, knowledge standard, circumstance, definition, exception, consent, writing, imputation, screening, supervision, comment, interpretation, product control, result state, uncertainty, and reviewer. The artifact contains 15 populated rows.

Read the complete record
The complete record keeps sources, stated facts, and questions for review separate. Pinned authorities: Verbatim state statute or official-source rule. N.C. R. Prof. Conduct 1.1: Competence example: The published North Carolina rule supplies an operative duty with knowledge, skill, thoroughness, and preparation terms.. N.C. R. Prof. Conduct 1.6: Confidentiality example: The published state rule illustrates prohibition, authorization, exception, and protective-action structure.. N.C. R. Prof. Conduct 5.5(a), (f): UPL example: The published state rule illustrates jurisdiction and assistance prohibitions.. Synthetic representation record: Classroom facts, not conclusions. Rule corpus: State-published rule text, adoption order, effective date, comments, ethics opinions, discipline decisions, statutes, and court rules. Scenario: Lawyer receives client information, delegates software task, encounters cross-border user, and considers disclosure. Question: Which actor, duty, mental state, exception, consent form, scope, and adopted variant control each event. Ethics trace: Constraint, exception, consent, safeguard, escalation, review. Parse: Actor, shall or shall not, may, knows or reasonably should know, object, circumstance, jurisdiction, temporal scope. Qualify: Definition, comment, exception, exception-to-exception, informed consent, confirmed in writing, tribunal, organization, prospective client. Connect: Imputation, screening, supervision, reporting, withdrawal, tribunal order, substantive law, evidence law, regulator process. Version: Model text, adopting jurisdiction, amendment, effective date, local variation, official interpretation and current authority. Evaluate: Satisfied, prohibited, permitted, exception possible, consent required, unknown, conflict, human review; never automated clearance.
Narrow summary
Treat Model Rules as versioned templates, parse the adopted rule's full constraint grammar, and output traceable uncertainty rather than compliance clearance.
