Thyra Thomson, Wyoming Secretary of State

Appellant's Claim

Wyoming's reapportionment plan to allocate one seat to Niobrara County in its House of Representatives was unconstitutional and substantially weakened the voting power of the plaintiff because it gave a small number of people "super" voting strength and totally disregarded a fundamental rule: one person, one vote.
