FAQs on Section 327 BNS

What is a decked vessel under Section 327(1) BNS?▼

A decked vessel is a boat or ship that has a deck, usually used for transport or navigation on water. Section 327(1) BNS protects decked vessels, vessels of twenty tons burden or upwards, rails, and aircraft from deliberate damage that can destroy them or make them unsafe.

Under Section 327(1) BNS, does the rail, aircraft, or vessel have to be completely destroyed?▼

No. The law also covers acts that render the rail, aircraft, or vessel unsafe. Even partial damage is enough if the required intent or knowledge and resulting danger are shown.

Is the offence under Section 327(1) BNS bailable?▼

No, it is generally treated as a non-bailable offence. Because the punishment is serious, the police and court deal with it more strictly than minor property offences.

How is Section 327(1) BNS different from ordinary mischief?▼

Ordinary mischief covers damage to property in general. Section 327(1) BNS is a much more serious form because it deals specifically with any rail, aircraft, decked vessel, or vessel of twenty tons burden or upwards, where damage poses a grave risk to human life and safe transport.

What does Section 327(2) BNS punish?▼

Section 327(2) BNS punishes committing, or attempting to commit, by fire or any explosive substance, the aggravated mischief described in Section 327(1) BNS against any rail, aircraft, decked vessel, or vessel of twenty tons burden or upwards.

Is intention necessary for the offence under Section 327(2) BNS?▼

Yes. The prosecution must show that the act or attempt was done intending to destroy or render unsafe the rail, aircraft, or qualifying vessel, or with knowledge that such a result was likely. Mere accident is not enough.

What is the maximum punishment under Section 327(2) BNS?▼

The punishment under Section 327(2) BNS is imprisonment for life, or imprisonment of either description for a term which may extend to 10 years, and the offender is also liable to fine.

Is an attempt also punishable under Section 327(2) BNS?▼

Yes. Section 327(2) BNS expressly punishes both committing and attempting to commit such mischief by fire or any explosive substance with the same punishment.

Section 327(1) BNS: Mischief with intent to destroy or make unsafe a decked vessel or one of twenty tons burden

▶

Bare Act Text

Whoever commits mischief to any rail, aircraft, or a decked vessel or any vessel of a burden of twenty tons or upwards, intending to destroy or render unsafe, or knowing it to be likely that he will thereby destroy or render unsafe, that rail, aircraft or vessel, shall be punished with imprisonment of either description for a term which may extend to ten years, and shall also be liable to fine.

Explained in Simple Words

Section 327(1) of the Bharatiya Nyaya Sanhita (BNS) deals with mischief committed to any rail, aircraft, decked vessel, or vessel of a burden of twenty tons or upwards, with the intent to destroy it or render it unsafe, or knowing that this is likely. This provision is aimed at protecting railways, aircraft, and larger or decked vessels from deliberate damage that can put lives and property at severe risk. The law is not limited to total destruction.

Even conduct that renders the rail, aircraft, or vessel unsafe can attract liability if the required intent or knowledge is proved. In practical terms, this section matters in cases involving sabotage, revenge, or deliberate tampering at railways, airports, ports, harbours, rivers, and ferry routes. It is a serious offence because damage to a rail, aircraft, or vessel can endanger passengers, crew, cargo, and public safety.

Key Ingredients

  • Commission of mischief to any rail, aircraft, or a decked vessel or any vessel of a burden of twenty tons or upwards
  • Intending to destroy or render unsafe, or knowing it to be likely that he will thereby destroy or render unsafe, that rail, aircraft or vessel
  • Punishment under Section 327(1) BNS of imprisonment of either description for up to ten years, and liability to fine

Mischief to any rail, aircraft, decked vessel, or vessel of twenty tons burden or upwards with intent to destroy or render it unsafe carries imprisonment of either description up to ten years, and liability to fine.

Real-World Example

At Surat docks, Prakash opened the sea-valves of an anchored decked cargo vessel of forty tons burden while the crew was ashore, intending to flood the engine room and render the ship unseaworthy. The watchman discovered the flooding and closed the valves before the vessel sank. Prakash knew that opening the sea-valves was likely to render the vessel unsafe. Prakash is punishable under Section 327(1) BNS.

When This Does Not Apply

  • The act did not amount to mischief under Section 324(1) BNS because the accused acted without intention or knowledge of causing wrongful loss or damage
  • The property affected was not a rail or aircraft, and was an undecked vessel of a burden of less than twenty tons
  • The accused neither intended nor knew it to be likely that his act would destroy or render unsafe that rail, aircraft, or vessel

Previous Law

IPC 437 → Section 327(1) BNS

Section 437 IPC corresponds to Section 327(1) BNS. Section 327(1) BNS expands statutory protection beyond decked or heavy maritime vessels to include any rail or aircraft alongside any decked vessel or any vessel of a burden of twenty tons or upwards, punishing anyone who intends to destroy or render unsafe that rail, aircraft or vessel or knows such result to be likely. The punishment of imprisonment of either description for up to ten years and liability to fine remains unchanged.

Section 327(2) BNS: Punishment for the mischief described in section 437 committed by fire or explosive substance

▶

Bare Act Text

Whoever commits, or attempts to commit, by fire or any explosive substance, such mischief as is described in sub-section (1), shall be punished with imprisonment for life or with imprisonment of either description for a term which may extend to ten years, and shall also be liable to fine.

Explained in Simple Words

Section 327(2) of the Bharatiya Nyaya Sanhita (BNS) deals with committing, or attempting to commit, by fire or any explosive substance, the mischief described in Section 327(1) BNS. In simple terms, it applies where a person uses fire or explosives to commit or attempt mischief against any rail, aircraft, decked vessel, or vessel of twenty tons burden or upwards, intending or knowing it to be likely to destroy it or render it unsafe. The law is aimed at conduct that creates an extreme risk to life, transport, and public safety.

This section applies both to the completed act and to an attempt to commit such mischief by fire or explosive substance. In practice, police, prosecutors, and courts look at whether fire or an explosive was used, whether the target was a qualifying rail, aircraft, or vessel under Section 327(1) BNS, and whether the accused intended or knew it was likely to destroy or render it unsafe.

Key Ingredients

  • Committing or attempting to commit mischief by fire or any explosive substance
  • The mischief is of the kind described in Section 327(1) BNS, directed against any rail, aircraft, decked vessel or vessel of twenty tons burden or upwards with intent or knowledge of destroying or rendering it unsafe
  • Punishment under Section 327(2) BNS of imprisonment for life, or imprisonment of either description for up to ten years, and liability to fine

Punishment

Non-Bailable ⓘCognizable ⓘNon-Compoundable ⓘ🏛️ Court of Session ⓘ

🔒 Imprisonment for life, or imprisonment of either description for a term which may extend to ten years.

💰 The offender is also liable to fine. The statute does not prescribe a mandatory fine or fix a maximum amount.

Mischief or attempted mischief by fire or explosive substance to destroy or make unsafe any rail, aircraft, decked vessel, or vessel of twenty tons burden or upwards carries imprisonment for life, or imprisonment up to ten years, and liability to fine.

Real-World Example

Late at night at a jetty near Machilipatnam, Aditya poured petrol on the deck of a moored fishing trawler of fifty tons burden and ignited it, intending to destroy the vessel. The crew aboard woke up and doused the flames before extensive fire damage occurred. Aditya committed mischief by fire with intent to destroy a qualifying vessel. Aditya is punishable under Section 327(2) BNS, which punishes the attempt equally with the completed act.

When This Does Not Apply

  • The act did not amount to mischief under Section 324(1) BNS because the accused acted without intention or knowledge of causing wrongful loss or damage
  • The mischief or attempt was carried out by means other than fire or an explosive substance
  • The property affected or targeted was not a rail or aircraft, and was an undecked vessel of less than twenty tons burden
  • The accused neither intended nor knew it to be likely that the act would destroy or render unsafe the rail, aircraft, or vessel

Previous Law

IPC 438 → Section 327(2) BNS

Section 438 IPC corresponds to Section 327(2) BNS. Section 327(2) BNS punishes committing or attempting to commit by fire or explosive substance such mischief as is described in Section 327(1) BNS. Because Section 327(1) BNS adds rail and aircraft alongside decked vessels and vessels of twenty tons burden, the aggravated fire and explosive offence now covers rail and aircraft as well as vessels. The punishment of imprisonment for life, or imprisonment of either description for up to ten years, and liability to fine, remains unchanged.
