Comcast Corp. v. Tillage; AT&T Mobility LLC v. McArdle
1. Whether the McGill rule falls outside the FAA’s saving clause because it is not a ground that “exist[s] at law or in equity” for the “revocation” of any contract?
2. Whether, even if the McGill rule falls within the FAA’s saving clause, it is otherwise preempted by the FAA because it interferes with fundamental attributes of arbitration by negating the parties’ agreement to resolve their dispute bilaterally?
