Cases checked to exist. Read the judgment before quoting a holding.

Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.

Most IT Act offences carry three years; a few carry much more. Sections 65, 66 and 66B to 66E are punishable with up to three years, which makes them cognizable and bailable under section 77B. The heavy offences are cyber terrorism (section 66F, up to life), protected systems (section 70, ten years), sexually explicit and child sexual abuse material (sections 67A, 67B, five and seven years) and the interception and blocking defaults in sections 69 and 69A (seven years). Section 66A no longer exists.

The entries for sections 67C, 68, 69B, 70B, 72 and 72A reflect the Jan Vishwas (Amendment of Provisions) Act, 2023, in force for the IT Act from 30 November 2023; older books show the earlier prison terms. Sections 84B and 84C add abetment (punishment for the offence abetted) and attempt (up to half the longest term).

2. Sections 65 and 66

Section 65 protects source code (listing of programmes, computer commands, design and layout and programme analysis) that is required to be kept or maintained by law. The act must be knowing or intentional concealment, destruction or alteration. Section 66 criminalises the ten civil wrongs of section 43 when done dishonestly (section 24 IPC: intent to cause wrongful gain or wrongful loss) or fraudulently (section 25 IPC: intent to defraud).

3. Section 66A: struck down and omitted

Section 66A punished sending, by computer or communication device, information that was grossly offensive or menacing, information known to be false sent persistently to cause annoyance, inconvenience, insult or ill will, and e-mails meant to annoy or mislead about their origin. In Shreya Singhal v. Union of India, 2015 INSC 257, the Supreme Court struck it down in its entirety as violating Article 19(1)(a) and not saved by Article 19(2): its terms were vague and overbroad, had no proximate link with public order, and would chill protected speech. It upheld section 69A and read down section 79 (see the note on intermediaries and blocking).

In October 2022 the Supreme Court directed that no citizen be prosecuted under section 66A, that reference to and reliance on it be deleted in all pending cases, and that the police not register complaints under it. The Jan Vishwas Act, 2023 then omitted section 66A from the statute with effect from 30 November 2023. In an MCQ, a false or annoying message is not an offence under section 66A; test it against the surviving sections and the BNS.

4. Sections 66B to 66F

5. Sections 67 to 67C

6. Sections 68 to 74

Sections 69, 69A and 69B (interception, blocking, traffic data) are covered in the note on intermediaries and blocking; only their punishments appear above. Section 70: the appropriate Government may declare a computer resource affecting Critical Information Infrastructure (whose incapacitation would have a debilitating impact on national security, economy, public health or safety) a protected system. Section 70B makes CERT-In the national agency for incident response. Sections 71, 73 and 74 are covered in the note on Certifying Authorities.

7. Procedure: sections 77A to 78 and 85

Cyber offences under the Bharatiya Nyaya Sanhita, 2023 (cheating, extortion, organised crime, defamation and others) are covered in the note on BNS and BNSS cyber offences.

How AIBE asks this

The usual question matches a section to its offence (66C identity theft, 66D personation, 66E privacy, 66F cyber terrorism) or to its maximum punishment (life for 66F, ten years for 70). The 2015 striking down of section 66A in Shreya Singhal is asked almost every cycle. Section 77B (cognizable and bailable) and section 78 (Inspector) are frequent one-liners.
