Rule of Law:
The Legal Principle
This section distills the key legal rule established or applied by the court—the one-liner you'll want to remember for exams.
Facts:
- Kenneth W. Colegrove and two other individuals were qualified voters residing in Illinois congressional districts.
- Illinois had not reapportioned its congressional districts since 1901, despite significant population shifts recorded in multiple federal censuses over more than forty years.
- Due to this failure to reapportion, there were gross disparities in the populations of Illinois's congressional districts.
- For example, one congressional district had a population of 914,053, while another had a population of only 112,116.
- Colegrove and the other plaintiffs resided in the most populous districts.
- This population imbalance caused the plaintiffs' votes to have significantly less weight in electing a U.S. Representative compared to votes cast in less populous districts.
