Definition - What does Proper Party mean?
A proper party is a person or entity, such as a business, that has an interest in a case that is being heard in court in terms of bearing a beneficial or negative outcome on the judgment in the case. In those instances, a proper party can be joined as a plaintiff in a lawsuit. In the same way, another party can also be brought in as a defendant to the action. Each party would be judged together, but their sentences would be varied depending on their level of interaction or culpability in the crux of the case.
Justipedia explains Proper Party
A proper party can give rise to a class action suit where several plaintiffs sue the same person or entity for damages relating to the same thing, such as a detrimental effect from a pharmaceutical medicine or negligence in a consumer product that gave rise to multiple instances of injury.
