Case Law Research Prompt
Case law research is the backbone of legal argument in common-law systems and increasingly influential in civil-law jurisdictions where courts publish reasoned opinions. This skill produces a structured research note covering the leading authorities on a given topic, formatted for immediate use in a court submission, arbitration brief, or client advice.
When to use this
- Preparing a skeleton argument or statement of case that must cite controlling authorities.
- A client or deal team needs to understand how courts have interpreted a specific clause type, legal doctrine, or statutory provision.
- The lawyer needs to brief junior associates on the leading cases before drafting submissions.
- Building a "state of the law" section for a legal opinion or an expert report.
- Checking whether the law has evolved since the lawyer last researched the point.
Required inputs
| Input |
Why it matters |
Sensible default |
| Legal topic or issue |
Defines the research question |
Ask the user to be as specific as possible |
| Jurisdiction(s) |
Case law is jurisdiction-specific; common-law vs. civil-law output differs fundamentally |
Ask the user — do not default to US or UK |
| Court level or forum |
Supreme courts / cassation courts carry more weight |
Default to appellate and supreme courts unless stated otherwise |
| Intended use |
Submission, opinion, client note, academic — shapes the depth and format |
Ask the user |
| Time period |
Recent cases most relevant; sometimes historical development matters |
Default to last 15 years unless stated otherwise |
Optional inputs
- Specific cases the user already knows about (to confirm they are included and to add authority).
- Opposing authority the user is trying to distinguish.
- Whether secondary sources (legal texts, academic commentary) should be included.
- Target audience (judge, client, arbitral tribunal) — shapes the technical depth.
Research methodology
Step 1 — Frame the legal question precisely
Restate the topic as a focused legal question (e.g., "When will an English court imply a duty of good faith into a commercial contract?"). A sharp question produces better-targeted results.
Step 2 — Identify the governing legal system
- Common law (DIFC, ADGM, UK, US, HK, SG): case law is binding precedent; landmark decisions must be cited.
- Civil law (UAE onshore, KSA, LB, EG, FR, most MENA): codified law is primary; court decisions (particularly cassation courts) have persuasive authority and are increasingly published and cited.
- Mixed / hybrid (Qatar QFC, Bahrain): apply the rules of the system governing the dispute.
Step 3 — Structure the research note per case
For each case, provide:
| Field |
Content |
| Case name |
Full case name as reported |
| Jurisdiction / court |
Court and country |
| Year decided |
Year of the decision |
| Facts |
2–4 sentence summary of the material facts |
| Legal issue |
The precise question the court decided |
| Decision |
The outcome and the court's reasoning |
| Principle established |
The rule of law the case stands for, in one sentence |
| Practical takeaway |
What a practitioner should do or avoid based on this case |
| Current status |
Still good law / overruled / qualified by later cases |
Step 4 — Organize authorities
Present cases in one or more of the following structures depending on the user's need:
- Chronological: Shows evolution of the law.
- By principle: Groups cases under the sub-rules they establish.
- For vs. against: Useful when the law is contested or the research is for adversarial use.
Step 5 — Synthesize
After the per-case analysis, provide a one-paragraph synthesis: what the current state of the law is, where the uncertainty lies, and any notable trends (judicial activism, divergence between jurisdictions, etc.).
Civil-law jurisdiction guidance
In UAE (onshore), KSA, Lebanon, and Egypt, the primary authorities are:
- The relevant Civil Code or Commercial Code (named, well-established provisions).
- Decisions of the Court of Cassation (Mahkamat al-Naqd in LB/EG; Supreme Court in UAE; Supreme Court / Board of Grievances in KSA).
- These decisions are often unpublished in searchable commercial databases; the researcher should acknowledge this limitation and note which decisions have been officially published.
In DIFC / ADGM, decisions are published on the respective court websites and follow common-law citation formats; binding precedent applies.
In international arbitration (ICC, LCIA, DIAC, ICSID), there is no doctrine of binding precedent; tribunals cite prior awards as persuasive authority only. Acknowledge this distinction when citing arbitral awards.
What not to do
- Do not fabricate case names, citations, or holdings. If a case cannot be verified, say so.
- Do not treat the same case as authoritative across different legal systems without noting the jurisdictional distinction.
- Do not omit unfavorable authorities — the lawyer needs to know what they face.
- Do not confuse persuasive and binding authority without flagging the distinction.
Output format
A research note structured as:
- Research question — one sentence.
- Jurisdiction and legal system — one sentence.
- Leading cases — per-case tables as above.
- Synthesis — one paragraph.
- Open questions / limitations — any gaps in the research, sources that could not be verified, or areas where expert local counsel should confirm.

Limits and escalation
- AI-generated case law research must be verified against primary sources before filing in any court or tribunal. Hallucinated citations have led to adverse costs orders.
- In KSA and LB, the availability of published court decisions is limited; escalate to local counsel for authoritative research.
- Where the law is actively evolving (e.g., AI liability, crypto-asset regulation), flag that recent regulatory guidance or unreported decisions may not be captured.
