Whether a plaintiff suing one alleged joint tortfeasor must join other potential joint tortfeasors as required parties under Federal Rule of Civil Procedure 19(a).
Holding
No. Potential joint tortfeasors subject to ordinary joint-and-several liability are permissive parties, not parties who must be joined under Rule 19(a).
Reasoning
The Court began with the established rule that a plaintiff need not sue all joint tortfeasors in one action. A claimant may proceed against one alleged wrongdoer without naming every other person who may share responsibility for the same injury.
The 1966 revision of Rule 19 did not alter that traditional rule. The Rule 19(a) Advisory Committee Notes expressly state that a tortfeasor with usual joint-and-several liability is merely a permissive party in an action against another tortfeasor with like liability.
Synthes, the surgeon, and the hospital were potential joint tortfeasors. Louisiana law did not supply a contrary rule requiring Temple to sue them together. Thus, the surgeon and hospital did not meet Rule 19(a)'s threshold for required joinder.
