The Court adopted the common interest rule as an exception to waiver of the work-product privilege. The common interest rule requires that the “transferor and transferee [must] anticipate litigation against a common adversary on the same issue or issues” and to “have strong common interests in sharing the fruit of the preparation efforts.”
