What is Plaintiff and defendant sides (polo ativo e passivo)?

The plaintiff side is the side that claims; the defendant side is the side that answers. The claimant is on the plaintiff side; the respondent, on the defendant side. Each side may bring together more than one party — several plaintiffs or several defendants — a case of joinder, common where the claim reaches an economic group.

Knowing who stands on each side is what allows deadlines, responsibilities and the meaning of each filing to be correctly assigned along the case timeline.

How LABORIS AI uses it

LABORIS AI classifies each act and document by its side of origin, distinguishing what comes from the worker, the company or the court — which makes the timeline reading precise and the relevance of each deadline correct.
