What a One-Case Summary Can’t Tell You

A one-case summary tells you what a court held. It cannot tell you what changed.

That gap is where a lot of careful work quietly goes wrong. You find a decision on point, you read the summary, you cite it — and you never learn that a later case narrowed the rule, or distinguished it, or set it aside. The summary was accurate. It was just not the whole picture.

A summary freezes a moment

A case summary captures one holding, at one point in time. It is useful, but it is a snapshot: it answers "what did this court decide here?" and stops. Doctrine, though, is not a snapshot. A rule stated in one case gets tested, qualified, and sometimes replaced in the cases that come after it. The summary you are reading may be describing the law as it stood then, not as it stands now.

Drift is where the mistakes live

The dangerous citation is rarely the invented one — that gets caught. It is the real case, correctly summarized, cited for a rule a later decision has already moved. It reads as solid because it is solid, as far as it goes. Catching that means asking a question a single summary can't answer on its own: has anything happened to this rule since?

Reading down a dimension

Answering it means putting cases next to each other rather than reading them one at a time. Line the decisions up and read across the same dimension — the facts against the facts, the issue against the issue, the reasoning against the reasoning. Read that way, the differences surface: where one court drew a line the next court moved, where a later case added a condition, where the rule quietly shifted. A stack of separate summaries hides exactly what a side-by-side comparison shows.

Verify before you cite

None of this replaces reading the decisions — it points you at which ones to read. Confirm the holding you are relying on still holds, and that the case still says what your source says it says, by opening the source itself. That habit is cheap when the tool keeps the real decision one click away, and expensive when it doesn't.

How Intellegal helps

Case Contrast is built for exactly this. It lines cases up side by side and lets you read down a dimension rather than through separate summaries — Basic across four dimensions (Focus of Dispute, Legal Facts, Judgment & Reasoning, Evidence), Advanced across seven, and it can compare more than two cases at once with a similar-and-difference analysis. Case-Law Analytics and Deep Synthesis surround it — search the case law, then research and synthesize with citations. Every case traces back to its source, so you can verify before you cite.

It supports the lawyer; it does not replace the lawyer. The judgment stays yours — the tool just makes the comparison, and the verification, fast.
