# Advanced: Multi-Case Synthesis

A single case brief is useful. But legal arguments are built on lines of cases — patterns across multiple holdings that establish, extend, or limit a rule. Synthesizing five or ten cases into a coherent argument is one of the most time-consuming tasks in legal practice. It is also one of the areas where AI provides the most leverage.

This lesson teaches you to move from single-case analysis to multi-case synthesis: comparing holdings, identifying trends, finding splits, and building the narrative arc of a legal argument.

Technique: Structured Case Comparison

I am researching the enforceability of forum selection clauses in
consumer contracts under federal law. Below are summaries of five
relevant cases.

For each case, extract:
1. Holding (enforceable or not)
2. Key factor(s) that drove the outcome
3. Standard of review applied
4. Whether the consumer had bargaining power
5. Whether the clause was in a clickwrap, browsewrap, or signed agreement

Then create a comparison table with these columns.

Finally, synthesize: What pattern emerges? What factors predict
enforceability vs. unenforceability?
