Yes. WhatsApp group messages can amount to defamation in India if the message contains a defamatory allegation about an identifiable person and the legal requirements for defamation are satisfied.
Under Section 356 of the Bharatiya Nyaya Sanhita (BNS), 2023, a person may commit defamation by making or publishing an imputation concerning another person with the intention, or knowledge/reason to believe, that it will harm that person's reputation. The provision is broad and is not limited to newspapers or public social-media posts.
When a WhatsApp message may be defamatory
For example, if someone posts in a WhatsApp group:
“ABC is a thief and has stolen money from the company.”
and the allegation is false, identifies ABC, and is communicated to other group members in circumstances that harm ABC's reputation, it could potentially constitute defamation.
Factors that may be important include:
The statement concerns an identifiable person.
It is communicated to at least someone other than the person concerned.
The statement is an allegation or imputation capable of lowering that person's reputation.
The person making the statement intended to harm the reputation, or knew or had reason to believe that it could do so.
The statement does not fall within one of the statutory exceptions, such as certain truthful statements made for the public good or good-faith communications made for protection of legitimate interests.
