Step 1: Understanding the Question.
The Code of Civil Procedure (C.P.C.), 1908, addresses the rights of aliens to file suits in India. Section 83 specifically deals with the provisions allowing an alien (a foreign national) to sue in Indian courts, subject to reciprocal treatment in their country, ensuring legal parity.
Step 2: Analyzing the Options.
- Option (a) Section 21A deals with objections to jurisdiction based on place of suing, not aliens.
- Option (b) Section 15 pertains to the court of first instance, unrelated to aliens.
- Option (c) Section 21B is not a recognized section in this context.
- Option (d) Section 83 directly addresses the right of an alien to sue, making it relevant.
Step 3: Conclusion.
The provision for aliens filing suits is governed by Section 83, making (d) the correct answer. This section ensures fair access to justice for foreign nationals.
