2003 U.S. Code
Title 28 - JUDICIARY AND JUDICIAL PROCEDURE
TITLE 28 - APPENDIX
General Order No. 41
Rule 18 - Joinder of Claims and Remedies

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

The final sentence added to subdivision (a) was intended to recognize both the right of a third party to assert a claim and the limitations on that right as set forth in 41 U.S.C. §114 and applicable case law.
