What is the test for determining whether a plaintiff is entitled to class-wide relief?

A court examining predominance must assess (1) "the elements of the claims and defenses to be litigated," (2) "whether generalized evidence could be offered to prove those elements on a class-wide basis or whether individualized proof will be needed to establish each class member's entitlement to relief," and (3) "whether the common issues can profitably be tried on a class[-] wide basis, or whether they will be overwhelmed by individual issues." Johnson v. Nextel Commc'ns Inc. , 780 F.3d 128, 138 (2d Cir. 2015).
