On April 14, 2025, ClassPass, a web-based company offering subscription services to third-party fitness classes, petitioned for rehearing en banc of the Ninth Circuit’s Chabolla v. ClassPass decision, which held that ClassPass’ users were not bound by the terms of ClassPass’ “sign-in wrap” agreement. The ruling has significant consequences for online companies using sign-in wrap agreements and for online contract formation and enforcement more generally. A sign-in wrap is a type of online agreement in which the agreement is hyperlinked on the website, but the user is not required to access, review, confirm an understanding, or otherwise affirmatively “assent” to be bound. If the Ninth Circuit does not grant ClassPass’ request and issue a new ruling in Chabolla, this case may signal the death knell for sign-in wraps, resulting in significant disruption, friction, and ultimately lower conversion for online companies who will be forced to redesign their sign-up flows to be click-wrap agreements (online agreements that require the user to affirmatively accept a company’s terms of use by clicking an assent box or button). Short of that, this decision increases business risk given that there are now conflicting opinions both within the Ninth Circuit and between the various Circuits. Click here to continue reading.
