DPIA Deep Dive: DPDPA Rules vs. GDPR Article 35

Data Protection Impact Assessments (DPIAs) have emerged as a cornerstone of proactive privacy compliance, requiring organisations to systematically identify and mitigate data protection risks before processing activities commence. As India’s Digital Personal Data Protection Act, 2023 (DPDPA) and its accompanying Rules are now fully operational, understanding its approach to DPIAs in comparison to established global benchmarks like the EU’s General Data Protection Regulation (GDPR) is crucial for Indian businesses navigating a complex regulatory landscape.

The DPDPA Framework: Mandates and Rules

The DPDPA, 2023, lays the foundational requirement for proactive risk management. Specifically, Section 10(2) empowers the Central Government to prescribe additional obligations for Data Fiduciaries, which crucially includes conducting Data Protection Impact Assessments. By July 2026, the DPDPA Rules have elaborated on these provisions, outlining specific scenarios where a DPIA is mandatory. These Rules typically mandate a DPIA for processing activities that involve a high risk to the rights of Data Principals. This includes, but is not limited to, large-scale processing of personal data, processing of sensitive personal data (as defined under other Indian laws or specified by the Rules), systematic profiling of Data Principals, use of new technologies, or processing that could lead to discrimination or significant economic loss.

Furthermore, the DPDPA Rules place enhanced obligations on “Significant Data Fiduciaries” (SDFs), as designated under Section 10(1). For SDFs, the scope of mandatory DPIAs is often broader and more prescriptive, covering a wider array of processing activities, and may include a requirement to periodically review and update existing DPIAs. The Rules also specify the minimum content of a DPIA, typically requiring a description of the processing operations, an assessment of the necessity and proportionality, an assessment of the risks to Data Principals, and the measures envisaged to address those risks. The Data Protection Board of India (DPBI) is empowered to issue guidance on the conduct and content of DPIAs, and potentially mandate consultation in specific high-risk scenarios.

GDPR Article 35: High Risk and Accountability

In contrast, GDPR Article 35 establishes a principle-based approach to DPIAs. It mandates a DPIA “where a type of processing, in particular using new technologies, and taking into account the nature, scope, context and purposes of the processing, is likely to result in a high risk to the rights and freedoms of natural persons.” Article 35(3) provides non-exhaustive examples of such high-risk processing, including systematic and extensive evaluation of personal aspects based on automated processing, large-scale processing of special categories of data (e.g., health, genetic, biometric data), or systematic monitoring of publicly accessible areas on a large scale.

GDPR Article 35(7) specifies the minimum content of a DPIA, which must include a systematic description of the processing, an assessment of the necessity and proportionality, an assessment of the risks to the rights and freedoms of data subjects, and the measures envisaged to address the risks, including safeguards, security measures and mechanisms to ensure the protection of personal data. A key feature of the GDPR is Article 36, which requires consultation with the supervisory authority if a DPIA indicates that the processing would result in a high risk in the absence of measures taken by the controller to mitigate the risk. This mandatory pre-processing consultation adds a layer of external oversight.

Key Differences: Triggers, Scope, and Oversight

Comparing the two regimes reveals both commonalities and distinct approaches. The DPDPA Rules, particularly for SDFs, tend to be more prescriptive regarding specific processing activities that trigger a DPIA, reflecting India’s legal tradition of detailed regulation. This is often stricter than GDPR’s more principle-based “high risk” threshold, which allows for greater organisational discretion in initial assessment, albeit with the burden of proof. While both regimes focus on identifying and mitigating risks to individuals, the DPDPA Rules might specify certain data types (e.g., biometric data, health data) or processing scales as inherently high-risk, regardless of a preliminary internal assessment.

On content, both frameworks largely align on the essential elements required in a DPIA: description of processing, risk assessment, and mitigation strategies. However, the DPDPA Rules might also explicitly require consideration of India-specific socio-economic contexts or data localisation implications, which are not direct considerations under GDPR.

A significant difference lies in the consultation mechanism. While GDPR Article 36 mandates consultation with the supervisory authority if a DPIA indicates unmitigated high risk, the DPDPA Rules might empower the DPBI to mandate DPIAs for certain sectors or processing types, and potentially require submission or consultation in specific circumstances for SDFs. The DPDPA Rules might be silent on a general mandatory consultation for all high-risk processing, instead relying on the DPBI’s proactive directives or post-facto audit powers under Section 29.

Interplay with Sectoral Regulations

For Indian businesses, the DPDPA’s DPIA requirements do not operate in a vacuum. Existing sectoral regulations, such as those issued by the Reserve Bank of India (RBI) for financial data or the IT (Reasonable Security Practices and Procedures and Sensitive Personal Data or Information) Rules, 2011, already mandate various forms of risk assessments, security audits, and data protection measures. The DPDPA Rules are designed to integrate with these, aiming for a unified approach. For instance, an RBI-mandated risk assessment for a new digital lending product might now need to be expanded or formally structured to meet the DPDPA’s DPIA requirements, covering a broader scope of personal data risks beyond just financial security. This means Indian entities must ensure their existing compliance frameworks are updated to explicitly incorporate DPDPA-mandated DPIA elements, avoiding duplication while ensuring comprehensive coverage.

Practical takeaway: Indian businesses, especially those designated as Significant Data Fiduciaries, must proactively review their data processing activities against the DPDPA Rules’ specific DPIA triggers. This involves establishing robust internal processes for risk assessment, documenting DPIAs thoroughly, and ensuring they are regularly updated. While GDPR provides a useful benchmark, organisations should pay close attention to the prescriptive elements of the DPDPA Rules and any specific guidance issued by the DPBI, particularly regarding mandatory consultation or submission for certain high-risk processing activities. Integrating DPDPA-compliant DPIAs into existing sectoral compliance frameworks (e.g., RBI, SEBI) will be key to achieving efficient and holistic data governance.
