AT&T's mandatory-arbitration clause is unenforceable in a class-action case over AT&T's throttling of unlimited data, a panel of US appeals court judges ruled this week.

The nearly five-year-old case has gone through twists and turns, with AT&T's forced-arbitration clause initially being upheld in March 2016. If that decision had stood, the customers would have been forced to have any complaints heard individually in arbitration.
