In Rent-A-Center, West v. Jackson, the justices divided, 5-4, in holding that an arbitrator, not a district court, will decide whether an arbitration agreement as a whole is unconscionable if the agreement explicitly delegates that issue to the arbitrator and the consumer or employee has failed to challenge the specific delegation clause.

“It greatly limits the ability of consumers and employees to challenge the fairness of arbitration agreements,” said Deepak Gupta of Public Citizen Litigation Group, co-counsel to Antonio Jackson, along with Public Justice and Ian Silverberg of Hardy & Associates in Reno, Nev., who argued the case.
