What is coplainant?

A complainant is an individual or entity that presents a complaint, typically in a legal context, asserting that they have suffered harm or injustice due to the actions of another party. The complainant initiates legal proceedings by filing a complaint with a court or relevant authority, seeking redress or resolution for the grievances they have experienced. In various settings, such as consumer protection or workplace disputes, the term can also refer to someone who raises concerns or reports issues related to unfair treatment or violations of rights.
