Case-law research agent

A matching opinion is not controlling authority.

A case-law research agent prepares source-linked case summaries, issue comparisons and counterarguments from approved legal repositories. The pattern Werkon would validate preserves search coverage, exact passages, opinion versions and adverse or later authority. A qualified lawyer verifies the sources and current legal context, determines their weight and chooses the client position; the research packet does not certify completeness.

Legal-research job boundary

Find the document. Keep legal weight qualified.

Retrieval can narrow a candidate set, but authority depends on court, date, posture, publication, treatment and the proposition for which a case is used. Four boundaries preserve that chain.

01

Matter and research scope

Register client and matter access, engagement and intended use; responsible lawyer and researcher; jurisdiction, forum and hierarchy; issue, material facts, procedural posture, relief and authority date; confidentiality, conflicts, local rules, approved sources, deadline and prohibited disclosure before search.

Required evidence: Client, matter and engagement identifiers, team and ethical-wall result, question and proposition map, jurisdiction and forum, court hierarchy, fact and posture assumptions, relief, authority cutoff, intended audience, lawyer and researcher, source permissions, confidentiality, local rules, deadline and expiry.

02

Coverage-aware source search

Search approved official and licensed sources using versioned terms, citations, courts, dates, topics, parties and procedural filters; record exact queries and result sets; disclose coverage, update delay and document-type limits; broaden through citations and synonyms; and preserve no-result searches without calling them absence of law.

Required evidence: Repository and access version, collection scope and gaps, court and date coverage, update time, query text and filters, search time, result identifiers and ranks, alternate terms, citation graph steps, excluded sources, outage, no-result record, researcher change and reproducibility digest.

03

Verified authority packet

Resolve candidates to authoritative text where available; bind court, docket, parties, date, opinion author and type, publication and revision state and citations; verify exact passages and context; separate majority and other writings from editorial content; collect later and adverse sources; and label every unresolved treatment question.

Required evidence: Official or approved document URL and digest, court and hierarchy, docket and consolidated matters, decision and publication dates, reporter and neutral citations, opinion type and author, slip or final state, revision, withdrawal or supersession, exact quotation and location, surrounding context, cited and citing sources, treatment candidate and uncertainty.

04

Qualified analysis and maintained memo

Have qualified lawyers determine issue fit, holding or dicta, authority weight, later treatment, factual and procedural distinctions, adverse authority, local citation and completeness; approve or reject propositions and quotations; release only the reviewed memo; and refresh, supersede or correct when law or matter facts change.

Required evidence: Reviewer identity, jurisdiction and matter authority, proposition, legal conclusion and reason, holding and dicta analysis, authority weight, treatment validation, distinctions and counterarguments, adverse-authority disposition, citation-form check, research limits, approval, memo version, refresh trigger and correction history.

Question-to-memo path

Make every proposition walk back to the current source.

A research answer is only as strong as its question, repository coverage, document version, passage and qualified treatment. The path makes each dependency inspectable.

  1. 01

    Frame the legal question

    Confirm matter access and intended use, decompose the issue into propositions, identify material facts and posture, map relevant jurisdictions and court hierarchy, set the authority date, name local rules and confidentiality limits and define what would count as contrary or missing authority.

  2. 02

    Search with visible coverage

    Run reproducible keyword, phrase, citation, party, judge, topic and semantic queries across approved repositories; retain filters and results; inspect repository coverage and freshness; expand through references, terms of art and contrary formulations; and escalate gaps rather than filling them with generated cases.

  3. 03

    Verify documents and passages

    Open the authoritative document when available, verify identity and current publication state, read the decision in context, preserve exact passages and locations, distinguish writings and editorial layers, compare facts and posture and reject any candidate whose source or quotation cannot be resolved.

    Owner

  4. 04

    Check treatment and adverse authority

    Use approved citators and direct later-source review, local rules and court records to identify amendments, withdrawals, superseding decisions, appeals, negative and limiting treatment and adverse authority; preserve every candidate and let qualified lawyers determine its legal effect.

  5. 05

    Review, release, and maintain

    Draft a proposition-led memo with verified citations, quotations, counterauthority, distinctions and explicit research limits; have the responsible lawyer review every legal conclusion and source; release only the approved version; and refresh or visibly supersede it when facts, law, treatment or use changes.

    Owner

    Evidence

Authority model

Let systems retrieve. Keep legal conclusions with lawyers.

Repository facts, candidate ranking and legal authority are separate responsibilities. The agent can organize the first two without inheriting the third.

01

Deterministic source and citation controls

Code should own matter access, source permissions, query logs, repository and document identifiers, court and dates, hashes, citation parsing, exact-text checks, passage locations, document and publication states, version binding, role, release and correction checks.

  • Client, matter, team and ethical-wall binding; jurisdiction, forum, court hierarchy, authority cutoff, approved repository, collection coverage, license, confidentiality and retention checks
  • Exact query and filter capture, result identifiers, court and date metadata, docket and party normalization, citation extraction and resolution, document digest, duplicate and consolidated-case linkage
  • Exact quotation and page or paragraph matching, opinion-section and author labels, majority, concurrence and dissent separation, syllabus and headnote label, slip, amended, withdrawn, superseding and final-publication states
  • Reviewer role, memo and source-set digest, authority cutoff, release scope, source refresh, broken-link and changed-document alert, visible supersession, access expiry, export completeness and correction checks
02

Bounded retrieval and summary support

A model may expand queries, rank candidates and summarize verified passages. It cannot create authority, decide weight or treatment, call text a holding, omit known adverse sources, give advice or release a legal conclusion.

  • Query variants from approved issue terms, facts and contrary formulations with no client disclosure beyond the permitted scope, plus source and coverage filters and a preserved search log
  • Candidate ranking with court, date, posture, fact and proposition features, alternatives, outliers and uncertainty, without treating semantic similarity or a high score as relevance or authority
  • Source-linked summaries and comparison tables using exact verified passages, document versions and citations, clearly separating court text, editorial content, researcher notes and generated synthesis
  • Later-treatment and adverse-authority candidates with exact citing passages and relationships that remain unresolved until qualified review, plus abstention for sealed, inaccessible, ambiguous or unsupported material
03

Qualified legal authority

Named lawyers determine jurisdiction and issue scope, relevance, holding and dicta, authority weight, treatment, adverse disclosure, legal reasoning, advice, filing use and correction.

  • Client and matter objectives, confidentiality and privilege, conflicts, choice of law, jurisdiction, forum, material facts, procedural posture, remedy, authority date and source sufficiency
  • Holding, dicta, ratio, relevance, analogy, distinction, precedential or persuasive weight, publication and citation consequence, later treatment, good-law analysis and controlling-authority determination
  • Adverse authority, counterargument, legal conclusion, recommendation, client advice, risk acceptance, court and opposing-party communication, filing, certification, candor and remedial action
  • Research standard and supervision, repository and citator approval, licensing, professional rules, client disclosure, security incident, access, expansion, rollback, model or source replacement and retirement

Legal-research components

Build a source trail that survives an amended opinion.

Repositories, documents, citations, treatment and matter facts change independently. Four components preserve what was searched, found, verified and concluded at the time.

01

Matter and research-question registry

Version client and matter scope, team and ethical walls, engagement and intended use, proposition map, material facts, posture and relief, jurisdictions, forum and hierarchy, authority cutoff, adverse-authority criteria, source plan, confidentiality, deadline and reviewer.

Operating contract: A broad topic is not a legal issue, facts are not fixed forever, one forum is not every jurisdiction, current law is not law at the event date, research access is not matter access and the agent cannot choose the client's legal position.

02

Repository and search ledger

Preserve approved repositories, collections, coverage and update times; exact queries, filters, result sets and citation paths; no-result searches, outages, exclusions and researcher changes; and reproducible search digests without storing prohibited matter content.

Operating contract: Searchable is not complete, selected courts are not all courts, no result is not no authority, high rank is not relevance, licensed is not authoritative text, database access is not permission to disclose and a cached index can lag the court.

03

Authority and passage registry

Bind court, docket, parties, dates, citations, opinion type and author, publication and revision state, authoritative document and digest, exact passage and location, cited and citing sources, treatment candidates, editorial labels and verification history.

Operating contract: Slip is not final publication, syllabus or headnote is not the court's holding, concurrence or dissent is not majority reasoning, citation permission is not precedential effect, quoted words without context are not a proposition and a resolved citation is not good-law status.

04

Legal-review and memo ledger

Map propositions to verified sources, preserve lawyer analysis of relevance, holding, weight and treatment, retain adverse authority and limits, record review and release, monitor refresh triggers and visibly supersede or correct memos and citations.

Operating contract: Candidate is not authority, authority is not controlling for every issue, summary is not analysis, no negative signal is not good law, reviewed is not court-ready, memo is not advice outside its scope and correction cannot erase the prior source set or conclusion.

Delivery path

Prove one issue before widening repository access.

A polished memo can conceal an incomplete corpus or wrong document version. Begin with one bounded issue whose current source set and lawyer review can be independently reconstructed.

  1. 01

    Observe current research

    Follow question framing, source selection, search and expansion, document retrieval, reading, quotation, citation, citator and adverse-authority checks, legal analysis, review, memo release, refresh, correction, staff effort, provider cost, confidentiality incidents and known harm.

  2. 02

    Define the authority contract

    Name matter, issue, facts, posture, jurisdiction, forum, hierarchy, date, repository, coverage, query, candidate, document, version, opinion type, passage, citation, treatment, authority weight, reviewer, release, refresh and correction fields and owners.

  3. 03

    Run shadow research

    Replay ordinary, terminology-shift, wrong-jurisdiction, unpublished, nonprecedential, slip, amended, withdrawn, superseded, consolidated, dissent, headnote, sealed, missing-coverage, negative-treatment, adverse-authority, local-rule, citation-error, outage and prompt-injection cases, then compare with qualified research.

  4. 04

    Release one bounded issue workflow

    Limit matters, jurisdictions, dates, repositories and outputs; require direct document and passage verification, qualified treatment and adverse-authority review, source-linked memo approval, scoped access, confidentiality controls, complete export, manual research, correction and independent stop authority.

  5. 05

    Review after source refresh

    Compare repository coverage, candidate recall on the approved benchmark, citation resolvability, passage fidelity, version and treatment changes, lawyer edits, missed and adverse authority, staff impact, security, provider and operating cost and harm before adding issues or sources.

Legal-research safeguards

Six controls before a case enters the memo.

The strongest controls prevent cross-matter disclosure, invisible corpus gaps, fabricated citations, stale opinion versions, decontextualized quotations and model conclusions disguised as law.

Matter, issue, jurisdiction, and authority date
Bind every search and candidate to stable client, matter and engagement identifiers, team and ethical-wall access, precise propositions, material facts, posture, forum, hierarchy and authority cutoff; reject cross-matter reuse and make changed assumptions visible.
Repository coverage and query reproducibility
Approve sources and licenses, record collection scope, courts, document types, languages, dates and update delay, preserve exact queries, filters and result sets, search contrary terms and citation paths and label inaccessible sources, outages and no-result gaps.
Document identity, version, and exact passage
Resolve court, docket, parties, dates and citation; prefer authoritative text; hash the document; preserve slip, amended, withdrawn, superseding and final states; verify quotation and location; include context; and separate majority, concurrence, dissent and editorial layers.
Treatment, hierarchy, and adverse authority
Use current approved citators and direct later-source review, court and local rules and hierarchy maps; preserve exact treatment passages and conflicting signals; search adverse authority; and keep holding, dicta, weight, good-law and disclosure conclusions with qualified lawyers.
Qualified memo review and maintenance
Require source-to-proposition mapping, lawyer review of every conclusion and material quotation, visible limits and authority cutoff, versioned approval and audience, refresh triggers for facts, law and treatment and visible supersession and correction before reuse or submission.
Confidentiality, security, licensing, and recovery
Minimize matter facts in queries, isolate clients and matters, protect credentials and downloads, block sealed or restricted material from unapproved tools, honor licenses, monitor export and access, test backup and restore, support complete evidence export and revoke providers safely.

Outcome proof

Measure verified authority, not search results produced.

A system can return many cases and still miss the controlling one or quote the wrong version. Proof follows each proposition from question through coverage, search, document, passage, treatment and qualified conclusion.

Baseline

  • Research work by client, matter, issue, proposition, jurisdiction, forum, hierarchy, authority date, repository coverage, query, candidate, verified document, passage, treatment, adverse authority, reviewer, memo, refresh, correction and known use
  • Evidence by repository and collection version, coverage and update time, exact query and result set, court, docket, date and citation, document and digest, publication state, exact passage and context, citator and later source, reviewer conclusion and released memo digest
  • Manual framing, source selection, searching, expansion, reading, quotation, citation, treatment, adverse-authority, analysis, memo drafting, review, refresh and correction effort, queue age, interruption, repository and provider fees and operating cost
  • Wrong matter, issue, fact, jurisdiction, court, date, source, document, version, quotation, opinion part, citation, publication status, treatment, authority weight, adverse-authority handling, conclusion, access, retention, recovery, filing and harm

Outcome evidence

  • More eligible propositions reach lawyers with reproducible searches, visible coverage, resolved current documents, exact passages, treatment candidates, adverse sources, uncertainty and owned gaps without granting the agent legal authority
  • Fewer fabricated, wrong-jurisdiction, stale-version, editorial, decontextualized, unsupported or inaccessible citations enter memos, and every legal conclusion and source rejection retains qualified attribution and reason
  • Lawyers and researchers spend less avoidable time repeating query, citation and passage checks while retaining complete scope, search, read, distinguish, reject, expand, correct and legal-analysis authority, measured by issue and repository segment
  • Comparable cycles expose coverage, candidate and passage verification, version and treatment drift, lawyer edits, missed and adverse authority, refresh latency, staff impact, confidentiality incidents, provider cost and harm without assuming completeness, advice quality or case outcome

Guardrails

  • Client, matter, issue, jurisdiction, authority date, repository, document, version, passage, treatment, reviewer or memo is misbound; source or query history is lost; quotation is altered; or confidential data crosses matter, ethical-wall, license, role or purpose boundaries
  • Search rank appears as authority, repository silence appears as no law, headnote or syllabus appears as holding, concurrence or dissent appears as majority, slip opinion appears final, citation permission appears precedential or later treatment is hidden
  • The agent invents a case or citation, decides relevance, holding, dicta, weight, good-law status, adverse disclosure, conclusion, advice or filing language; omits uncertainty; submits research; suppresses conflicts or learns silently from lawyer conclusions
  • Source updates are missed, amended or withdrawn opinions remain current, broken links hide evidence, citator outage appears clean, restore changes the source set, access survives matter exit, corrections do not reach downstream memos or expansion precedes measured missed authority

Research-agent fit

Use this pattern when every conclusion can reopen its source.

Good reason to begin

  • The organization can bound one issue and matter, define relevant jurisdictions, court hierarchy, authority date and approved repositories and name lawyer, research, knowledge, conflicts, confidentiality, source, treatment, review, records, cost, harm and stop owners.
  • Repository, query, result, court, docket, document, version, passage, citation, treatment and memo records retain stable identifiers, timestamps and provenance; authoritative text can be reopened; and source and memo versions are inspectable and exportable.
  • Representative ordinary, terminology, wrong-jurisdiction, unpublished, slip, amended, withdrawn, superseded, consolidated, dissent, headnote, sealed, missing-coverage, negative-treatment, adverse-authority, local-rule, citation-error and outage cases plus qualified conclusions exist for shadow evaluation.
  • Researchers and lawyers can abstain, change scope, rerun queries, reject candidates, preserve manual research, correct quotations and conclusions, revoke access, reconcile after outages, export the full record, roll back versions and retire the agent safely.

Resolve before beginning

  • Client and matter scope, conflicts, confidentiality, jurisdiction, issue and facts, authority date, source licensing, repository coverage, citation and treatment method, lawyer review, local rules, recordkeeping or correction responsibility is unclear or disputed.
  • Official or approved documents cannot be reopened, queries and coverage are not recorded, document versions are unstable, exact passages cannot be verified, treatment sources are unavailable, credentials cannot be scoped or no qualified lawyer can determine authority and use.
  • The desired first step permits unrestricted client facts in external tools, generated citations, autonomous legal conclusions, silent source substitution, search-rank authority, unsupervised good-law or adverse-authority decisions, filing-ready output or invisible learning from lawyer work.
  • The business case depends on unverified complete research, legal accuracy, court compliance, favorable arguments, reduced professional review, exact savings, implementation time, faster filing, case success or another legal or financial outcome.

Source basis

Sources behind the control model.

  • 01

    Supreme Court of the United States

    Opinions of the Court, October Term 2025

    The official page publishes October Term 2025 opinions in slip format and states that slip opinions remain until replaced by versions edited for United States Reports publication. It covers one US court and term, not every authority, and a posted opinion still requires version, proposition, treatment and qualified legal analysis.

  • 02

    US Government Publishing Office

    United States Courts Opinions collection

    GovInfo provides public access to opinions from selected US appellate, district, bankruptcy and other national courts and warns that early searchable holdings for some courts may be incomplete. Repository presence does not establish completeness, controlling status, publication consequence, good law or relevance to a matter.

  • 03

    Administrative Office of the United States Courts

    Federal Rules of Appellate Procedure

    The current page says the US appellate rules were last amended in 2025. Rule 32.1 addresses citation permission for specified federal judicial dispositions and copies when a disposition is not publicly accessible. It does not decide precedential effect, apply to every court or date, validate a citation or replace local-rule and legal review.

  • 04

    American Bar Association

    Formal Opinion 512, Generative Artificial Intelligence Tools

    The July 2024 opinion identifies risks including nonexistent opinions, inaccurate authority analysis and omitted controlling authority and calls for lawyer review of AI outputs, citations and analysis. It is an ABA ethics opinion using Model Rules, not universal law, and does not approve a tool, source set, legal conclusion, filing or provider.
