The case Shaw v. Reno (1993) involved a challenge to a North Carolina congressional district map, alleging racial gerrymandering. The plaintiffs argued that the district was drawn with the intention of creating a majority-minority district, thereby violating the Equal Protection Clause of the Fourteenth Amendment. The Supreme Court agreed, holding that the district was so irregular on its face that it could only be understood as an effort to segregate voters based on race. This ruling established that while states can consider race when drawing districts to comply with the Voting Rights Act, race cannot be the predominant factor.
This Supreme Court decision is significant because it placed limits on the practice of creating majority-minority districts, even if intended to increase minority representation. It affirmed that using race as the primary factor in drawing district lines is unconstitutional, as it reinforces racial stereotypes and undermines the principle of equal representation. The case established a key precedent that continues to shape redistricting practices and litigation surrounding voting rights.
