Today in Supreme Court History: September 25

Tennant v. Jefferson County Comm’n, 567 U.S. 758 (decided September 25, 2012):  Full Court, reversing District Court, approves of West Virginia Legislature’s reapportionment of its three Congressional seats, one of eight competing plans.  This short decision goes through how the Court decides whether a redistricting comports with “one person, one vote”: population differential (not dispositive; one of the rejected plans had a differential of only one person between smallest and largest districts); whether incumbents would be forced into same district; whether counties or cities would remain whole, etc.  The approved plan had a differential of only 0.79% between smallest and largest, which Court admitted in these days of computerized algorithms might be “large” deviation, but o.k. here.
