Reversed and remanded in a case involving the enforcement of arbitration clauses in online contracts. Plaintiffs filed suit against defendant alleging violations of Massachusetts consumer-protection statute. Defendant operates a ride-sharing service requiring customers to register using the Uber App. In the app is a page that has a button that will take you to Terms and Conditions, which a user is not required to accept and which contains an agreement to arbitrate any dispute. The district court granted defendant's motion to compel arbitration and dismissed the complaint. In reversing and remanding the First Circuit held that the terms of the agreement were not reasonably communicated to plaintiffs.
