Definition - What does Impleader mean?
An impleader is a type of legal procedure in which a defendant in a civil case brings forth a third party because they believe that the third party may actually be liable for the claims made by the plaintiff.
Impleaders are only allowed to take place if they are approved by a judge.
Justipedia explains Impleader
If an impleader occurs in a civil suit, then it can potentially change the entire course of the lawsuit. This is because it could shift liability from the defendant to the third party.
In some situations, the third party is found to have full liability. In others, the third party is found to have no liability, or partial liability. It all depends on the specific case.
Whichever party is found responsible will have to face the consequences.
