Estoppel, Competency of Witnesses, and Examination of Witnesses notes — Unit 5
Free unit-wise study notes on estoppel, competency of witnesses, and examination of witnesses for Law of Evidence, Semester 4 of Bachelor of Laws (LLB) — key concepts, examples, important questions and a revision checklist for semester exams.
Stopping flip-flops and examining witnesses. This final unit covers the equitable doctrine of Estoppel (Section 115) which prevents a person from denying their previous statements. It then explores who is a Competent Witness (Sections 118-122), protecting privileged communications. Finally, it outlines the art of trial advocacy: Examination-in-Chief, Cross-Examination, Leading Questions, and Impeaching the credit of a witness (Sections 135-167).

1. The Doctrine of Estoppel (Section 115)
Estoppel is an equitable doctrine based on fairness. It stops a person from "blowing hot and cold" or changing their story to suit their changing interests.
⇒The Definition (Section 115)
When one person has, by his declaration, act or omission, intentionally caused or permitted another person to believe a thing to be true and to act upon such belief, neither he nor his representative shall be allowed, in any suit or proceeding between himself and such person, to deny the truth of that thing.

2. Conditions for Estoppel
For estoppel to apply, three conditions must be satisfied:
Representation: There must be a representation (by word, act, or silence/omission) made by one person to another.
Belief: The other person must have believed the representation to be true.
Action: The other person must have acted upon that belief and altered their position to their detriment.
⇒Key Principles
No Estoppel against a Statute: You cannot use estoppel to force someone to do something illegal. (If a minor lies about his age to get a loan, he is NOT estopped from pleading minority later to avoid repaying it, because a contract with a minor is void by statute).
Estoppel is a rule of civil evidence: It generally does not apply in criminal cases.

3. Competency of Witnesses (Sec 118-121)
Who can step into the witness box and testify? The Evidence Act has a very broad approach.
⇒Who may testify? (Section 118)
ALL persons shall be competent to testify unless the Court considers that they are prevented from understanding the questions put to them, or from giving rational answers, by tender years, extreme old age, disease (of body or mind), or any other cause.
Child Witness: A 5-year-old child CAN testify, provided the judge asks them preliminary questions to ensure they understand the duty to speak the truth and can give rational answers.
Lunatic (Sec 118): A lunatic is competent to testify if they are experiencing a lucid interval (a period of sanity) and can understand the questions.
⇒Dumb Witness (Section 119)
A witness who is unable to speak may give evidence in any other manner in which they can make it intelligible, as by writing or by signs, in open court. This is deemed to be oral evidence.

4. Privileged Communications (Sec 122-129)
To protect certain important societal relationships, the law prevents some competent witnesses from being forced to testify about specific private matters.
⇒1. Spousal Privilege (Section 122)
No person who is or has been married shall be compelled to disclose any communication made to them during marriage by any person to whom they are or have been married; nor shall they be permitted to disclose any such communication without the consent of the person who made it.
(Exception: Suits between the married persons themselves).
⇒2. Professional Privilege (Section 126)
No advocate/attorney shall be permitted, without their client's express consent, to disclose any communication made to them in the course of their employment as an advocate.
(Exception: If the communication was made in furtherance of any illegal purpose - e.g., "Help me forge this document").

5. Examination of Witnesses (Section 137)
When a witness takes the stand, their questioning happens in three distinct stages.
1. Examination-in-Chief: The examination of a witness by the party who calls him. (e.g., The prosecutor questioning the victim). The goal is to let the witness tell their story and establish the facts.
2. Cross-Examination: The examination of a witness by the adverse party. (e.g., The defense lawyer questioning the victim). The goal is to test the veracity, memory, and credibility of the witness, and to destroy the case made in chief.
3. Re-Examination: The examination of a witness, subsequent to the cross-examination, by the party who called him. The goal is strictly to explain matters referred to in cross-examination (not to introduce entirely new evidence without the court's permission).
The order must always be: Examination-in-Chief -> Cross-Examination -> Re-Examination (Section 138).

6. Leading Questions (Sections 141-143)
⇒What is a Leading Question?
Any question suggesting the answer which the person putting it wishes or expects to receive. (e.g., Instead of asking "What time did you leave?", asking "You left at 9 PM, didn't you?").
⇒When are they NOT allowed? (Sec 142)
Leading questions must NOT be asked in Examination-in-Chief or Re-Examination, if objected to by the adverse party.
(Why? Because the witness is 'your' witness. You shouldn't be putting words in their mouth).
⇒When are they ALLOWED? (Sec 143)
Leading questions may be asked in Cross-Examination.
(Why? Because the adverse witness is presumed hostile, and the lawyer needs to corner them and test their narrative).

7. Impeaching Credit & Hostile Witness
⇒Impeaching Credit of Witness (Section 155)
The adverse party can impeach (destroy) the credibility of a witness in cross-examination by:
Showing the witness is unworthy of credit (by calling other witnesses to testify to their bad reputation for truth).
Proof that the witness has been bribed.
Proving former statements inconsistent with their current testimony (e.g., "In your police statement you said the car was red, today you say it's blue").
⇒Hostile Witness (Section 154)
What if you call a witness to support your case, and they suddenly flip on the stand and start supporting the opponent? (Often due to bribery or threats).
The Court may permit the party who called the witness to ask them any questions which might be put in cross-examination. Essentially, the court declares the witness 'hostile', allowing you to cross-examine your own witness to expose their lie.

8. Refreshing Memory & Judge's Power
⇒Refreshing Memory (Section 159)
A witness may, while under examination, refresh their memory by referring to any writing made by themselves at the time of the transaction. (e.g., A police officer referring to his case diary while testifying about an investigation that happened 5 years ago).
⇒Judge's Power to Put Questions (Section 165)
The Judge is not just a silent referee. To discover or obtain proper proof of relevant facts, the Judge may ask any question he pleases, in any form, at any time, of any witness or of the parties, about any fact relevant or irrelevant.
Neither party can object to the Judge's questions, nor can they cross-examine the witness upon the answers given to the Judge, without the leave of the Court.

9. Conclusion and Exam Strategy
⇒Summary of Master Concepts
Estoppel (Sec 115): Prevents a person from denying their previous representation if someone acted on it.
Competency (Sec 118): Everyone (including children and lunatics) is competent if they can understand questions and give rational answers.
Privilege: Spousal (Sec 122) and Professional/Lawyer (Sec 126) communications are protected.
Leading Questions: Banned in Chief; Allowed in Cross.
Hostile Witness (Sec 154): When a witness turns against the party who called them, the party can cross-examine them.
⇒University Exam Tips for this Unit (Premium Advice)
Estoppel vs Res Judicata: A classic comparison. Estoppel is a rule of evidence based on equity (stops you from speaking differently). Res Judicata is a rule of civil procedure based on public policy (stops courts from deciding the same case twice).
Hostile Witness: Explain Section 154 clearly. Mention that the evidence of a hostile witness is not entirely washed off the record; the judge can still rely on the truthful parts.
Leading Questions: Always explain why they are allowed in cross-examination (to corner a hostile opponent) but not in chief (to prevent coaching).
