Short Summary: Several North Carolina residents challenged a proposed, unusually shaped district. They believed that the only purpose of the district was that it would definitely elect African-American representatives.
Constitutional Issue: The constitutional issue here was whether racial gerrymandering took place with this district (it was very narrow) and if the district raised an Equal Protection Clause question.
Holding and Constitutional Principle: The Supreme Court held, in a majority opinion authored by Sandra Day O’Connor, that because the district was shaped in such a clearly odd way, it was enough to prove that there was a very apparent effort to separate voters racially.
Further Impact: A key fact about this case is that majority-minority districts can be constitutionally challenged if race was the sole factor in their creation.
