# Comparing Cases

## <mark style="color:blue;">**1. Why Compare Cases?**</mark>

Law isn’t just about knowing one rule — it’s about understanding how rules apply in different situations. Comparing cases helps you:

* See patterns in the law.
* Spot differences that matter (and differences that don’t).
* Build stronger arguments by showing why your case is *like* or *unlike* earlier cases.
* Synthesize rules from multiple sources.

When you compare cases, you’re training your brain to:

1. **Recognize core legal ideas** in each case.
2. **Notice how courts weigh facts** to apply those ideas.

## <mark style="color:blue;">2. How to Compare</mark>

When reading and comparing cases, focus on these three elements:

1. **The Rule**
   * Does the case apply the same rule as your other case?
   * Has the rule been changed, narrowed, or expanded?
2. **The Facts**
   * Which facts made a difference to the court’s decision?
   * Are the important facts in one case also present in the other?
   * If facts differ, do those differences matter under the rule?
3. **The Reasoning**

   * Did the court focus on fairness, efficiency, public policy, or a bright-line test?
   * Did it interpret a statute broadly or narrowly?
   * How does this reasoning compare to other cases?

One of the best ways to see how cases fit together is to break them into the same categories and put them side by side.

<table data-header-hidden data-full-width="false"><thead><tr><th></th><th></th><th></th><th></th><th></th></tr></thead><tbody><tr><td>Case name</td><td><p>Issue/</p><p>questions</p></td><td>Rule</td><td>Facts</td><td>Answer+ Reasoning</td></tr><tr><td><br></td><td><br></td><td><br></td><td><br></td><td><br></td></tr><tr><td><br><br><br><br></td><td><br></td><td><br></td><td><br></td><td><br></td></tr><tr><td><br></td><td><br></td><td><br></td><td><br></td><td><br></td></tr><tr><td><br></td><td><br></td><td><br></td><td><br></td><td><br></td></tr></tbody></table>

Let’s walk through how to fill this chart in for one case.

**Example:** *Smith v. Grocery Mart*

* **Case Name:** *Smith v. Grocery Mart* (Ky. Ct. App. 2017)
* **Issue / Question:** Is a grocery store liable when a customer slips on a spill it knew about but didn’t clean up right away?
* **Rule:** A property owner must take reasonable steps to address hazards they know about or should know about.
* **Key Facts:** Spill in produce section; employees saw it; no cleanup or warning for 20 minutes; customer slipped and broke her wrist.

| **Case Name**            | **Issue / Question**            | **Rule**                         | **Key Facts**                                                                       | **Answer + Reasoning**                        |
| ------------------------ | ------------------------------- | -------------------------------- | ----------------------------------------------------------------------------------- | --------------------------------------------- |
| *Smith v. Grocery Mart*  | Store liability for known spill | Reasonable steps after knowledge | Employees saw spill, no cleanup, 20 min delay                                       | Liable – actual knowledge, no action          |
| *Davis v. Corner Market* | Store liability for spill       | Reasonable steps after knowledge | Spill occurred moments before fall; no one saw it; routine inspections every 30 min | Not liable – no actual/constructive knowledge |
|                          |                                 |                                  |                                                                                     |                                               |

Once you have charts for two cases, you can compare them side-by-side to see patterns.&#x20;
