Case Theory Simulator
Purpose
Committing to the wrong legal theory late in a case is expensive. This workflow forces a structured multi-theory analysis at the outset (or at a strategy inflection point), surfacing the strengths and vulnerabilities of each theory, modeling opponent responses, and producing a comparative assessment that leads to a recommended primary and fallback theory.

Logic
Step 1 — Theory generation
If fewer than two theories are provided, generate candidates based on the facts and jurisdiction. For example, in a contract dispute:
- Theory A: breach of contract (primary)
- Theory B: unjust enrichment / quantum meruit (fallback if contract unenforceable)
- Theory C: tortious interference (if third party involved)
- Theory D: fraud / misrepresentation (if false statements alleged)
In civil-law jurisdictions (LB, EG, UAE onshore, KSA): also consider delictual liability (civil fault) as an alternative to contractual theories, especially where contractual privity is absent.
Step 2 — Theory-by-theory analysis
For each theory, produce:
Strengths:
- Legal elements that are satisfied by the evidence
- Favorable precedents (jurisdiction-specific)
- Procedural advantages (e.g., lower burden of proof, availability of injunctive relief)
- Jury / judge appeal (for jury trials; bench trial considerations)
Weaknesses:
- Missing elements
- Adverse precedents or statutory bars
- Evidence gaps requiring additional discovery or expert testimony
- Affirmative defenses opponent can raise
- Exposure to counterclaims
Evidence requirements:
- What must be proved and how
- Documents, witnesses, and experts needed per element
Step 3 — Opposing-counsel response model
For each theory, model the three most likely opposing responses:
- Motion to dismiss / strike: which elements of this theory are vulnerable to pre-trial challenge?
- Affirmative defense: what statutory or equitable defenses will be raised?
- Counterclaim / cross-claim: does this theory open the client to a counter-attack?
MENA-specific traps:
- UAE / KSA onshore courts: opposing counsel may file a criminal complaint in parallel to a civil action (filing criminal fraud or embezzlement complaints as a negotiation tactic is common). Flag if the facts could support a criminal referral by either side.
- Lebanon: courts have wide discretion in equity-like relief; the opponent may seek provisional attachment (saisie conservatoire) against assets.
- Egypt: the defendant in commercial arbitration can file a nullity action before Egyptian courts under the Arbitration Law if procedural grounds exist — factor in if the matter involves an arbitration clause.
Step 4 — Settlement value estimate
Produce a structured settlement-value range:
| Scenario |
Probability |
Estimated outcome |
| Best case (client wins all claims) |
20% |
USD X |
| Most likely (mixed result) |
50% |
USD Y |
| Worst case (client loses, counterclaim succeeds) |
15% |
USD -Z |
| Settlement (negotiated resolution) |
15% |
USD W |
Expected value: weighted average of the above scenarios minus litigation cost.
Calibration factors:
- Forum: arbitration (predictable, limited discovery) vs. court (variable, discovery-intensive)
- Judge / arbitrator profile if known
- Jurisdictional enforcement difficulty (e.g., enforcing a DIFC judgment in KSA onshore courts requires separate enforcement proceedings)
- Client's risk appetite and time horizon
Step 5 — Recommended approach
Output a structured recommendation:
- Primary theory: the most viable path to relief
- Fallback theory: to plead in the alternative if primary theory fails
- Theories to drop: explain why (weakens overall credibility, creates estoppel risk, etc.)
- Key next steps: evidence gathering, experts to retain, pre-filing motions, early settlement indicators

**Strengths**: [...]
**Weaknesses**: [...]
**Opponent response**: Motion to dismiss (limitation issue), Counterclaim (offset)
### Theory 2: Unjust Enrichment

### Settlement Value Matrix
| Scenario | Probability | Outcome |
| Best case | 20% | $2.4M |
| Most likely | 55% | $900K |
| Worst case | 15% | -$200K |
| Settlement | 10% | $600K |
**Expected value (before costs):** $820K
---
### Recommendation
**Primary**: Theory 1 — Breach of Contract (strongest documentary support)
**Fallback**: Theory 2 — Unjust Enrichment
**Drop**: Theory 3 — insufficient evidence of fraudulent intent without expert testimony
**Immediate actions**: Preserve all communications; retain financial expert; file protective order.
Jurisdictional Notes
- DIFC / ADGM: English common-law applies. Theories must satisfy common-law elements. Expert evidence on quantum is standard practice in commercial disputes. Settlement discussions are formally without prejudice.
- UAE onshore: Civil law; the court may award damages only for actual (proven) loss and direct causation. Penalty clause enforceability depends on UAE Federal Civil Transactions Law. Courts actively seek to moderate disproportionate penalties.
- KSA: Commercial disputes before specialized commercial courts or the Board of Grievances. Sharia-based contract law applies — interest claims (riba) must be reframed as late-payment compensation. Arbitration is common in commercial contracts.
- Lebanon: Courts apply Lebanese Code of Obligations and Contracts. Civil and commercial proceedings are often slow; interim relief (juge des référés) is a practical tool. Parallel criminal complaints (especially fraud) are a common litigation tactic.
- Egypt: Egyptian civil law follows French civil-law tradition. Litigation is slow in state courts; arbitration via CRCICA is faster. Egyptian courts apply strict evidentiary rules — witness testimony is less relied upon than documents.
