"In affirming its denial of class certification, the court recognized that ERISA Section 502(a)(3) does not address which parties may be sued under the statute and 'admits of no limits . . . on the universe of possible defendants.' However, the court recognized that there are limits on a plaintiff's ability to bring a Section 502(a)(3) claim against a nonfiduciary.... The court ultimately found that the appropriate equitable relief requirement doomed the plaintiff's class claims against the third-party administrator." [Duggan v. Towne Properties Group Health Plan, No. 15-623 (S.D. Ohio, Mar. 31, 2019)]
