A quasi-judicial proceeding is a trial that adopts the form of a judicial process without a formal basis in law.
[1] The term also implies that these authorities are not routinely responsible for holding such proceedings and often may have other duties.
In short, an administrative function is called ‘quasi-judicial’ when there is an obligation to assume a judicial approach and to comply with the basic requirements of natural justice.
Thus, the fundamental purpose of a quasi-judicial hearing is to provide the affected parties due process.
[2] Due process requires notice of the proceedings and an opportunity to be heard.
