How to build a case law research matrix for Employment Discrimination Matters

Build the matrix around disputed legal propositions, not a collection of case summaries. For each proposition, record the statute, court, authority weight, procedural posture, precise holding, material facts, distinctions, and subsequent treatment. Connect that analysis to identified matter evidence and the decision counsel must make. The resulting deliverable is a source-linked research matrix that separates controlling from persuasive authority, tests favorable and adverse arguments, and identifies what requires further legal research or factual development before drafting.

When to use this workflow

Use this workflow when litigation counsel or an in-house team must evaluate a discrimination theory, prepare dispositive-motion arguments, assess an opponent’s authorities, or identify legally significant gaps for targeted discovery. It is especially useful when opinions involve similar employment actions but different statutes, decisionmakers, explanations, or procedural stages.

The discussion emphasizes US federal district-court litigation. Identify the governing statute, forum, circuit, local rules, and case-specific orders before adapting the matrix. Federal procedure does not automatically govern state litigation, arbitration, or administrative investigations; the federal rules define their own scope. Federal Rules of Civil Procedure, Rule 1. (uscourts.gov)

This workflow organizes research; it is not a universal discrimination-elements checklist. Keep separate statutory theories distinct unless researched authority supports treating their standards together.

What you need

Begin with a defined research question and a traceable matter record:

• Matter parameters: forum, statutory theories, represented party, procedural stage, research cutoff, and intended work product.
• Issue statements: disputed propositions concerning intent, employer explanations, comparator treatment, evidentiary sufficiency, or another identified issue.
• Core documents: pleadings, motion papers, agency submissions, policies, decision records, and testimony with stable document identifiers.
• Fact outline: alleged protected status, challenged action, relevant actors, decision dates, stated reasons, and contested facts. Separate allegations from supported facts.
• Research materials: full opinions, pinpoint citations, official source links, and a method for checking subsequent history and treatment.

For explanation-based research, collect contemporaneous and later accounts separately. Differences between a termination letter, agency response, and deposition answer may reflect contradiction, added detail, or different speakers’ knowledge. Preserve that question rather than resolving it through shorthand. Record whether the relevant actor’s knowledge is established, disputed, or unknown.

Use the template

Use the Employment Discrimination Matters — Case law research matrix below. You can copy this table into your working document or spreadsheet. Create one row per material proposition; an opinion may require several rows.

Use stable IDs such as R-01 so drafting notes can refer to the same analysis. The authority field should contain the case citation, pinpoint, and full-opinion link. Record the decision date and authority classification separately: a court name alone does not explain the opinion’s relevance to the present forum or issue.

Distinguish holdings from dicta, party arguments, and questions left unanswered. In the facts field, record similarities and distinctions with document IDs, pages, Bates numbers, or deposition page-and-line citations. Use linked working notes when the comparison exceeds a readable cell.

The treatment field records the verification method, date, and result. “Not checked” is acceptable during research, but it blocks reliance until resolved. The action field identifies the proposed use, next task, responsible person, and completion point relative to drafting.

Step by step

1. Define the decision the research must support

Write the intended decision before searching: for example, whether the record supports arguing that an employer’s explanation could be disbelieved on an ADEA summary-judgment motion. Identify the claim, represented party, and procedural stage in that sentence.

Divide broad questions into propositions that may receive different answers. Whether disputed performance records undermine an explanation is not the same question as whether a proposed comparator satisfies the applicable standard. Likewise, retaliation and status-discrimination questions should not share a row merely because they concern the same termination.

Record in the template: a separate ID and question for each proposition, with statute, theory, and posture populated. Assign an owner if the issue’s scope remains unsettled.

2. Establish the authority framework

Identify the court system and each opinion’s relationship to the matter. Separate controlling from persuasive authority, and explain classifications that depend on publication status, the issue decided, or subsequent history. Flag uncertain classifications for counsel rather than assigning weight from a search-result heading.

Start with applicable higher-court authority, then research the governing jurisdiction’s application of the precise proposition. Include limiting and contrary decisions. A shared term such as “pretext” does not establish that cases address the same statutory or procedural question.

Record in the template: court, decision date, authority weight, and any missing controlling-law analysis. Classify the proposition being used, not every statement in the opinion indiscriminately.

3. Extract the holding with its procedural limits

Read the opinion itself, including its account of the record and disposition. Write a narrow paraphrase, add a pinpoint, and state the limitation most likely to affect the matter.

For example, Reeves explains that a prima facie case combined with sufficient evidence that an employer’s justification is false may permit a finding of intentional discrimination. That showing does not invariably establish liability, and independent additional discrimination evidence is not invariably required. The case concerned an ADEA jury verdict reviewed under Rule 50. Reeves, 530 U.S. 133, 147–149. (govinfo.gov)

Record in the template: proposition, pinpoint, posture, and limitation. Do not convert “may permit” into “requires,” or treat an evidentiary holding as a complete statement of claim elements.

4. Compare legally material facts with the matter record

Identify facts the opinion treats as significant, then map them to evidence. For employer explanations, compare speaker, timing, decision authority, knowledge, and supporting records. For comparators, capture role, supervisor, decisionmaker, period, conduct, and outcome as research inputs—not as a substitute for the governing test.

Use source citations rather than narrative confidence. Link an explanation to the actual communication or testimony. Label missing disciplinary information “unknown,” not “no prior discipline.” Distinguish the decision date from the communication and effective dates when timing matters to the proposed analogy.

Record in the template: favorable similarities, adverse distinctions, exact record links, and uncertainties. Identify counsel’s inference separately from the document’s contents.

5. Separate merits research from discovery and evidence questions

Create linked rows when the question concerns obtaining evidence rather than its sufficiency. In federal district court, Rule 26(b)(1) limits discovery to relevant, nonprivileged matter proportional to the case; information need not be admissible to be discoverable. This does not authorize unrestricted personnel-file discovery. Federal Rules of Civil Procedure, Rule 26(b)(1). (uscourts.gov)

A useful HR record also requires separate foundation analysis. Rule 901 addresses authentication; Rule 803(6) states conditions for the regularly conducted activity hearsay exception. Authentication alone does not resolve hearsay, including statements embedded in a record. Federal Rules of Evidence, Rules 901 and 803(6). (uscourts.gov)

Record in the template: a distinct discovery or foundation question linked to the merits row. Label rules as rules, not case holdings, and assign any necessary interpretive case-law research.

6. Verify treatment and test the adverse reading

Check subsequent history and treatment, then read material later decisions rather than relying only on treatment signals. Determine whether later authority narrows the proposition, distinguishes the posture, or addresses another statute. Check opponents’ cases independently as well.

Write the strongest plausible adverse reading of each central opinion. An unfavorable factual distinction may matter more than favorable abstract language. Record a verification date for each authority; do not imply that checking one opinion validates every case it cites. Preserve superseded conclusions in working notes so the team can understand changes.

Record in the template: verification date, method, material treatment, adverse reading, and unresolved research tasks. Hold unverified authorities from drafting reliance.

7. Convert the matrix into a research recommendation

Group completed rows by question and write a short synthesis: supported proposition, boundaries, evidence supporting the analogy, and unresolved issue that could change the recommendation. Explain how adverse authority affects the proposed argument rather than merely listing it.

Classify rows as ready for drafting, requiring authority verification, or requiring factual development. These are internal workflow statuses, not legal conclusions. Avoid numerical confidence scores that conceal missing controlling authority or disputed facts.

Record in the template: proposed use and next action. Assign open questions to a person and specify whether resolution is necessary before the memorandum, motion, or response can rely on the proposition.

Worked example

Fictional scenario: Counsel represents Liora Chen in an ADEA termination dispute against fictional employer Northmere Components. The team is preparing a memorandum for anticipated summary-judgment briefing. All parties, matter documents, and document contents below are fictional; Reeves is actual authority.

F-101, a termination letter at page 1, attributes the decision to recurring inventory-report errors. F-102, an internal audit at pages 3–4, identifies a software import problem affecting two cited reports. F-103, an agency submission at page 6, adds missed deadlines. The available documents do not establish whether the decisionmaker knew about the import problem before termination or whether other reported errors remained unexplained.

A personnel index, F-104 at page 2, identifies a younger analyst who remained employed. It does not establish that analyst’s supervisor, errors, or disciplinary history. The record supplied for this exercise also does not establish every component of Chen’s claim.

The matrix changes the memorandum’s direction. Counsel can investigate an explanation-based argument without asserting that the audit proves discriminatory intent. The deadline explanation needs contextual comparison, not an automatic “shifting reasons” label. The analyst remains a lead, not an established comparator. The two Reeves rows identify different tasks while expressly preventing premature reliance on unfinished research.

Common mistakes

• Collecting cases without propositions. Replace broad summaries with a question and pinpoint-supported answer per row.
• Flattening procedural posture. Preserve the researched opinion’s posture and verify its proposed application to the present task.
• Calling every changed explanation contradictory. Compare speaker, timing, context, and supporting records first.
• Assuming comparator status from title or outcome. Identify missing facts and research the claim-specific standard.
• Recording only favorable authority. Put adverse holdings and material distinctions beside the proposed argument.
• Treating a source link as treatment verification. Record subsequent-history and treatment checks separately from retrieving the opinion.

Final quality check

Before using the matrix, confirm:

• Every row answers an identified legal question.
• Each authority has verified full text and an accurate pinpoint.
• Statute, theory, court, authority weight, and posture are recorded.
• Paraphrases preserve qualifications and distinguish holdings from other statements.
• Material comparisons cite documents or testimony and label unknown facts.
• Subsequent treatment is checked, or reliance is expressly blocked.
• Adverse authority and contrary factual readings are addressed.
• Open issues are resolved or assigned with clear consequences for drafting.

Frequently asked questions

Should each case receive only one row?

No. Separate distinct propositions and limitations. Reuse the citation consistently, but make each row independently useful to the drafting lawyer.

Can Reeves supply the entire research framework?

No. Use its verified evidentiary holding for the proposition it addresses. Research the governing claim requirements, later controlling authority, and proposed procedural application separately; do not expand the holding into a universal discrimination test.

What belongs in a row when comparator information is missing?

Identify the unknown facts precisely, link available evidence, and assign both legal research and factual verification. Similar titles or different outcomes do not complete the analysis.

How should counsel handle an approaching drafting deadline?

Prioritize essential propositions, adverse authority, and unresolved controlling-law questions. Tell the drafting lawyer which rows remain unusable and why. An explicit limitation is preferable to presenting unfinished research as settled.
