Sections 4 to 10 read as a sequence - from the moment data is asked for to the moment it must be deleted. Accountability never moves: the Data Fiduciary answers for its processors, whatever the contract says.
Nine closed categories where consent is not the basis. Read them narrowly: they are the exception, not a second consent regime.
Section 8(1) makes the Data Fiduciary responsible for compliance irrespective of any agreement to the contrary, and irrespective of any failure by the Data Principal to carry out her own duties. Two consequences follow, and both are easy to miss.
First, a processor contract allocates work and cost, never liability. When a processor loses data, the Board still looks at the Data Fiduciary. Second, a Data Principal who breaches her section 15 duties - say, by supplying false information - does not thereby reduce your obligations towards her data. Her breach is separately penalisable at up to ₹10,000; yours is not offset by it.
Note also the narrower scope of section 8(3). The duty to ensure completeness, accuracy and consistency bites only where the data is likely to be used for a decision affecting the Data Principal, or disclosed to another Data Fiduciary. It is not the general accuracy principle GDPR applies to all processing.
Four of these duties are stated in the Act as principles and filled in by the DPDP Rules, 2025. The Rules are where the engineering work actually lives.
A delivery app collects a customer's mobile number so it can send order updates. Six months later, marketing wants to use the same numbers for promotional messages. Follow the sections in order and the answer is not a judgement call.
The trap is step three. Teams arriving from GDPR reach for legitimate interests to justify the marketing use, find it missing, and then try to read section 7(a) - data voluntarily provided - as a substitute. It is not: 7(a) is tied to the purpose for which the data was volunteered, which brings you back to order updates.
Two audiences and two clocks. Run them in parallel, because the obligation to the individual does not wait on the report to the Board.
Sections 4 to 10 sit in the eighteen-month tranche of the commencement notification, so these duties bite in mid-May 2027. The Rules are already notified, which means what they will require is known rather than speculative - see the commencement timeline and what binds you until then.
