Back in May I posted a short entry on impleader. Below is a video on impleader that I just uploaded.
In the federal courts impleader is governed by Rule 14 of the Federal Rules of Civil Procedure. States also allow impleader.
Generally speaking, the Federal Rules (and state rules) favor resolving related disputes in a single case to promote efficiency. Impleader allows a defendant to sue a third party based on the principle that if the defendant is liable to the plaintiff, then this third party is liable to the defendant. The defendant is now also called a third party plaintiff. The original plaintiff's lawsuit against the defendant/third party plaintiff and the defendant/third party plaintiff's lawsuit against the third party defendant are resolved in the same case.
Let's say A sues B. B's insurance policy requires C to reimburse B if B owes money to A. B can implead C into the case. B sues C as a third party plaintiff arguing that if B owes any money to A, C must owe money to B.
