Section 327 punishes mischief to a rail, an aircraft, a decked vessel, or a vessel of a burden of twenty tons or upwards, when the offender intends to destroy it or make it unsafe, or knows that he is likely to do so. The basic offence carries imprisonment of up to ten years and fine; committing or attempting the same mischief by fire or an explosive substance carries imprisonment for life, or imprisonment of up to ten years, and fine. It replaces IPC Sections 437 and 438 and adds “rail” and “aircraft” to the things protected.
Verified against the National Crime Records Bureau's official BNS–IPC concordance (Sankalan Portal) and cross-checked directly against the bare text of both Acts. Section 327 draws on two sections of the old Indian Penal Code, 1860 (Sections 437 and 438), each surviving as one of its two sub-sections. The concordance does not attach a change marker to Section 327, but comparing the text itself shows that the scope widens: sub-section (1) protects things that IPC Section 437 did not, and sub-section (2), which cross-refers to sub-section (1), reaches them too. Structurally, the two IPC sections are merged into the two sub-sections of this one section; because the widened scope accompanies that merger, both rows are classed Substantively changed:
| BNS 327(x) | Covers | IPC, 1860 equivalent | Category |
|---|---|---|---|
| (1) | Mischief to a rail, aircraft, decked vessel or vessel of twenty tons burden or upwards, with intent to destroy or make unsafe | S.437 “Mischief with intent to destroy or make unsafe a decked vessel or one of twenty tons burden” | Substantively changed |
| (2) | The same mischief committed, or attempted, by fire or explosive substance | S.438 “Punishment for the mischief described in section 437 committed by fire or explosive substance” | Substantively changed |
Structurally, IPC Sections 437 and 438 are merged into this one section, and substantively the scope is widened to a rail and an aircraft. A word-by-word comparison of the bare text of BNS Section 327 against IPC Sections 437 and 438 shows the following. In sub-section (1), IPC Section 437 read “Whoever commits mischief to any 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 vessel”. BNS 327(1) reads “to any rail, aircraft, or a decked vessel or any vessel of a burden of twenty tons or upwards, ... that rail, aircraft or vessel”. The only textual differences are the added words “rail, aircraft, or a” (before “decked vessel”) and “rail, aircraft or” (before “vessel” in the closing words), and the punishment (imprisonment of either description for up to ten years, and liability to fine) is unchanged. In sub-section (2), IPC Section 438 referred to “such mischief as is described in the last preceding section”, whereas BNS 327(2) refers to “such mischief as is described in sub-section (1)”; the punishment (imprisonment for life, or imprisonment of either description for up to ten years, and liability to fine) is unchanged, apart from punctuation, and because sub-section (1) now includes a rail and an aircraft, sub-section (2) reaches them by that cross-reference, so the scope of sub-section (2) widens as well, although its own words are otherwise unchanged.
(1) 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.
(2) 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.

Sub-section (1) has three ingredients. First, the offender “commits mischief” as defined in Section 324(1) — so he must have acted with intent to cause, or knowing that he was likely to cause, wrongful loss or damage to the public or to any person, and must have destroyed property or changed it injuriously. Second, the mischief is done “to any rail, aircraft, or a decked vessel or any vessel of a burden of twenty tons or upwards”. Third, the offender must have a further, specific state of mind: he must be “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”. That third ingredient is a more specific state of mind than the one in Section 324(1): it concerns destroying the rail, aircraft or vessel, or making it unsafe.
“Vessel” is defined in Section 2(32) as anything made for the conveyance by water of human beings or of property. Section 2 does not define “rail”, “aircraft”, “decked vessel” or “burden”; this page uses those words in their everyday sense. The sub-section does not say how a vessel’s burden is to be measured, beyond the words “twenty tons or upwards”. The punishment is imprisonment of either description for up to ten years, “and shall also be liable to fine”. Under the BNSS First Schedule the offence is cognizable, non-bailable and triable by the Court of Session, and it is not compoundable. IPC Section 437 protected decked vessels and vessels of twenty tons burden or upwards only; the addition of “rail” and “aircraft” is the change made by the BNS, as the concordance section above explains.
Sub-section (2) takes everything in sub-section (1) — the mischief, the rail, aircraft or vessel, and the specific intention to destroy it or make it unsafe (or knowledge that this is likely) — and adds the means: “by fire or any explosive substance”. It applies to the person who “commits, or attempts to commit” that kind of mischief by those means. Naming attempt in the sub-section itself means the text expressly reaches an offender whose attempt does not succeed in destroying the rail, aircraft or vessel. Section 2 does not define “fire” or “explosive substance”; this page uses those words in their everyday sense. The sub-section refers to “such mischief as is described in sub-section (1)”, so the rail, aircraft and vessel wording of sub-section (1) applies to it.
The punishment is imprisonment for life, or imprisonment of either description for up to ten years, “and shall also be liable to fine”. Imprisonment for life is one of the punishments listed in Section 4(b), and it is available here but not under sub-section (1). Under the BNSS First Schedule the offence is cognizable, non-bailable and triable by the Court of Session, and it is not compoundable. The wording follows IPC Section 438, with a reference to sub-section (1) in place of “the last preceding section”.
Under sub-section (1), imprisonment of either description for up to ten years, and liability to fine. Under sub-section (2), where the mischief is committed or attempted by fire or an explosive substance, imprisonment for life, or imprisonment of either description for up to ten years, and liability to fine.
Under the First Schedule to the BNSS both sub-sections are cognizable and non-bailable, and are triable by the Court of Session. Neither sub-section appears in the compounding tables of BNSS Section 359, so they are not compoundable.
Sub-section (1) requires that the mischief be done “intending to destroy or render unsafe, or knowing it to be likely that he will thereby destroy or render unsafe” the rail, aircraft or vessel. That is in addition to the intent or knowledge of wrongful loss or damage required for mischief under Section 324(1).
A “decked vessel”, or any vessel of a burden of twenty tons or upwards. Section 2(32) defines “vessel” as anything made for the conveyance by water of human beings or of property. “Decked vessel” and “burden” are not defined in Section 2.
Yes. Sub-section (2) applies to a person who “commits, or attempts to commit, by fire or any explosive substance” the mischief described in sub-section (1), and carries the higher punishment.
Sub-section (1) now protects a rail and an aircraft as well as decked vessels and vessels of twenty tons burden or upwards; IPC Section 437 named only the vessels. Sub-section (2) refers to the mischief described in sub-section (1), where IPC Section 438 referred to the preceding section, so it also reaches a rail and an aircraft. The punishments are unchanged.
