"It's a sorid business, this divving us up by race." Chief Justice John Roberts
LULAC vs. Perry: 2006 case challenging Texas' redistricting.
SCOTUS ruled that only one new district violated the Voting Rights Act. Dist.23 (61% Hispanic), held by Henry Bonilla (Hispanic Republican).
Ruling stated that while it was redrawn to be a 'majority minority', it wasn't Hispanic enough.

Chief Justice Roberts asked LULAC's attorney: "What number of minority voters is just right to make a district qualify as "Hispanic-opportunity", rather than one masquerading as such?" He got no answer.
