Rule 18. Joinder of Claims and Remedies

(a) Joinder of Claims. A party asserting a claim to relief as an original claim, counterclaim, or third-party claim, may join, either as independent or as alternate claims, as many claims as the party has against an opposing party.

(b) Joinder of Remedies. Whenever a claim is one heretofore cognizable only after another claim has been prosecuted to a conclusion, the two claims may be joined in a single action; but the court shall grant relief in that action only in accordance with the relative substantive rights of the parties.
