Today, the U.S. Supreme Court granted the objectors' cert. petition in Frank v. Gaos, No. 17-961. The underlying Ninth Circuit opinion is In re Google Referrer Header Privacy Litigation, 869 F.3d 767 (2017), which is discussed in this blog post.
In Google Referrer, Ninth Circuit affirmed the district court's order approving a class action settlement in which all monetary proceeds were distributed to cy pres recipients, reasoning that distributions to individual class members were not economically feasible. 869 F.3d at 741-42.
The cert. petition contended that the case presented an opportunity for the Court to reach the "fundamental concerns surrounding the use of such remedies in class action litigation" identified by Chief Justice Roberts in his 2013 "statement respecting the denial of certiorari" in Marek v. Lane, no. 13-136. (See these blog posts.) It looks like at least four justices agreed.
