Legal guide | Updated 19 October 2026

Section 100: Statutory text

The heading of Section 100 of the Delhi Police Act, 1978 is Wilful trespass. The text reproduced in the original article reads:

Whoever without satisfactory excuse wilfully enters or remains in or upon any dwelling-house or premises or land or ground attached thereto, or on any ground, building, monument or structure belonging to Government or used for public purposes, or on any vehicle, shall, on conviction, whether he causes any actual damage or not, be punished with imprisonment which may extend to seven days or with fine which may extend to one hundred rupees, or with both.

The provision addresses deliberate unauthorised presence in the places it specifies. It expressly states that actual damage is not necessary for the punishment provision to apply.

Essential ingredients of wilful trespass under Section 100

1. Entry or continued presence

The person must enter or remain in or upon a place or vehicle covered by the provision. Remaining after permission is withdrawn may be relevant, depending on the circumstances.

2. Wilful conduct

The word "wilfully" indicates deliberate conduct. Accidental entry or a genuine mistake should not automatically be equated with a wilful act; evidence of knowledge, permission and surrounding events matters.

3. Absence of satisfactory excuse

The statutory wording includes "without satisfactory excuse". An asserted lawful authority, permission, emergency or other explanation must be evaluated on the evidence and applicable law. The phrase does not mean that every explanation must be accepted.

4. Specified location

The entry or presence must concern a type of property or vehicle described in Section 100. Whether the location falls within the statutory description is a factual and legal question.

Which premises and places are covered?

  • Dwelling-house: A residence or house used as a dwelling.
  • Premises, land or ground attached to a dwelling: Areas connected with the residence, subject to the provision's wording and facts.
  • Government property: Grounds, buildings, monuments or structures belonging to Government.
  • Places used for public purposes: Grounds, buildings, monuments or structures used for public purposes, even where the ownership and usage questions need separate examination.
  • Vehicles: The section expressly includes wilful entry or remaining on a vehicle without satisfactory excuse.

Public ownership or public use does not necessarily mean unrestricted access to every part of a property. Equally, ordinary authorised access to a place open to visitors should not automatically be characterised as trespass.

Punishment under Section 100 of the Delhi Police Act

According to the statutory wording reproduced above, conviction may result in imprisonment for up to seven days, or a fine of up to Rs. 100, or both. These are the amounts and duration in the supplied statutory text; any subsequent legislative amendment or applicable special provision should be checked against an up-to-date official version before legal reliance.

Section 100 contains its own penalty. It should not be confused with Section 97, which addresses contraventions of Sections 80 through 96.

Is proof of damage necessary?

No. The express words "whether he causes any actual damage or not" mean that the absence of physical damage does not, by itself, exclude Section 100. The other statutory ingredients must still be established.

Section 100 and criminal trespass under the Bharatiya Nyaya Sanhita, 2023

The Bharatiya Nyaya Sanhita, 2023 (BNS) came into force on 1 July 2024, subject to applicable transitional and saving provisions. Section 329 of the BNS addresses criminal trespass and house-trespass. It uses different ingredients, including specified intent for criminal trespass, and provides a separate penalty framework. A violation of Delhi Police Act Section 100 must therefore not be assumed to prove BNS Section 329 automatically.

The Delhi Police Act provision focuses on wilful entry or remaining without satisfactory excuse in listed places. A BNS allegation requires independent proof of its own statutory elements. Depending on the facts, property damage, intimidation or other conduct may implicate additional provisions, but liability cannot be inferred from presence alone.

For procedure, the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) generally replaced the Code of Criminal Procedure, 1973 for new proceedings from 1 July 2024, subject to savings. The classification and procedure for any particular charge should be checked in the applicable legislation.

Illustrative situations

  • Possible contravention: A person deliberately enters a fenced government compound despite clear restrictions and has no satisfactory excuse.
  • Possible contravention: A person intentionally remains inside another person's dwelling after consent to stay has clearly ended, without satisfactory explanation.
  • Not automatically a contravention: A visitor enters a government office during visiting hours with lawful permission.
  • Fact-dependent: A person enters a restricted area during an emergency to obtain urgent help. The asserted excuse, actual circumstances and relevant rules require assessment.

These are examples for understanding the provision, not conclusions about any individual case.
