Explanation:

- Section 503 of the Indian Penal Code defines criminal intimidation.

- It discusses causing alarm by threats to another person, their reputation, or property.

- Importantly, “injury” in this section includes both legal and illegal harm.

- Legal harm means even lawful acts—if threatened maliciously—can be intimidation.

- So, the section covers threats of both legal and illegal injury.
