According to Order 3 Rule 1 of the Civil Procedure Code 1908:-
"Appearances, etc., may be in person, by recognised agent or by pleader
any appearance, application or act in or to any Court, required or authorised by law to be made or done by a party in such Court, may, except where otherwise expressly provided by any law for the time being in force, be made or done by the party in person, or by his recognized agent, or by a pleader appearing, applying or acting, as the case may be, on his behalf:
Provide that any such appearance shall, if the Court so directs, be made by the party in person.”
So, the appearance of a person without a pleader is a complete discretion of court. The layman who want to fight his own case must satisfy the Court first that he has proper knowledge of the procedural law, drafting and other Laws and secondly that the Court do not have to waste time in every step of the way to make him understand the laws as huge cases are pending. There will be no scope of excuse that the layman was ignorant of any law.
