the issue, and whether the issue was proffered by one and controverted by another. See Gies v. Nissen Corp., 57 Wis.2d 371, 204 N.W.2d 519, 525 (1973). The Wisconsin Supreme Court considers an issue to be “joined” between the parties when one party has served a formal pleading asking for relief against the other party. See id. (first co-defendant who served cross-claim for contribution on second co-defendant had joined the issue of their respective liability to the plaintiff; thus, first co-defendant was bound by judgment in that action, which dismissed second co-defendant). The formal-pleading requirement serves to ensure that the parties joined the issue between them by requesting relief, and that either party can enforce such requested relief.
