Neither the Act nor section 36 provides for appearance of the parties themselves when they are individu- als or companies or corporations. The Tribunals and the Labour Courts being quasi-judicial authorities dealing with rights affecting the parties cannot adjudicate their disputes in absence of the parties. It is, therefore, incumbent upon the Tribunals and Labour Courts to afford reasonable opportunity to the parties to appear before them and hear them while adjudicating industrial disputes.

Section 36, therefore, is not exhaustive in the sense that besides the persons specified therein there cannot be any other lawful mode of appearance of the parties as such. As indicated earlier section 36 does not appear to take count of companies and corporations as employers. It is, however, common knowledge that industrial disputes are raised in a predominantly large number of cases where companies or corporations are involved.
