Dismissal Motion for Missing Fabricator
Blue Production sued East Industries for defective control boards supplied under contract. East moved before answering to dismiss under Rule 12(b)(7) because Ash Industries had fabricated the boards and assumed warranty duties. The court considered whether Ash's absence prevented complete relief between the named parties.
Diversity Plaintiff Adds Same-State Party
Summit Machines sued Metro Fabrication on a diversity contract claim. Metro joined Apex as a third-party defendant. Summit then asserted direct defect claims against Apex. Apex moved to dismiss those claims because adding a same-state party through Rule 19 joinder would destroy complete diversity.

River Ocean sued in State A court over land in State B. The court applied its own procedural rules to questions of joinder of parties while using the law selected under the most-significant-relationship test for substantive property issues.
Dismissal Without Prejudice for Missing Party
A plaintiff failed to join a required party under Rule 19 after repeated court orders. The defendant moved to dismiss under Rule 41(b). The court dismissed the action without prejudice because the order expressly noted the failure to join a Rule 19 party.
Collateral Estoppel After Joint Trial
Two defendants were tried together for robbing six poker players in one game. After acquittal on charges involving five victims, the state sought to prosecute the sixth robbery separately. The court held that the prior acquittal barred relitigation of the shared identity issue.

Claim Preclusion of Federal Judgment
A diversity action was dismissed on statute-of-limitations grounds. The defendant later argued that the dismissal barred a subsequent state-court suit on the same claim. The court examined whether the federal judgment carried claim-preclusive effect under state law.
