| Court: | US Supreme Court |
| Facts: | Euclid wants to zone: lands between two railroad lines are zoned for industrial use. This devalues a major portion of the plaintiff's land. |
| Posture: | Suit alleging 14A violations (due process and equal protection). Lower court agreed, and blocked enforcement of the zoning. |
| Issue: | Does the power exist to zone? |
| Holding: | Yes. |
| Rule: | In order to call this unconstitutional, you'd have to show that it was clearly arbitrary and unreasonable, having no relation to the public health, safety, morals, or general welfare. |
| Reasoning: | Zoning is a modern invention. The legislature's judgement must control, if the position is debatable. |
