Just claiming to be a public servant, even as a joke, is a crime under this section.

Courts have clarified that the offence requires not just the false claim but also doing or attempting some act using that fake official position.

This section is the same as cheating (Section 419 IPC).

Section 170 specifically targets impersonating a public servant's official character, while cheating under Section 419 requires proof of deception causing wrongful loss or gain — the two overlap but are legally distinct.

Indian Penal Code, 1860

Section 170

repealed

Personating a public servant

Whoever pretends to hold any particular office as public servant, knowing that he does not hold such office or falsely personates any other person holding such office, and in such assumed character does or attempts to do any act under colour of such office, shall be punished with imprisonment of either description for a term which may extend to two years, or with fine, or with both.§

Why this exists

The provision was part of the original Indian Penal Code of 1860, drafted to protect the integrity of public offices and public trust in government functionaries. Colonial administrators were concerned that impostors claiming official positions (like tax collectors, police officers, or magistrates) could deceive citizens, extract money, or misuse authority. By criminalizing not just the false claim but the act done under that false claim, the law targets real harm caused by impersonation, not mere boasting.

How courts read it

Indian courts have generally held that mere false claim of holding an office is not enough; the offence is complete only when the person also does or attempts some act 'under colour of' that office. Courts have distinguished this section from Section 419 (cheating by personation) by noting that Section 170 focuses specifically on impersonating a public servant's official character and using that assumed authority, whereas cheating requires proof of deception causing wrongful loss or gain. Judgments have also clarified that the impersonator need not actually gain anything personally; attempting the act is enough.
