10 Supreme Court rulings every PIO must know (2026)

The 10 most-cited Supreme Court rulings on RTI — what they hold, when to cite them, and how they shape PIO decisions. RTI Act §3, §6, §7, §8, §10, §22.

RTI Act §3, §6, §7, §8, §10, §22 — section-wise text in the RTI Act 2005 complete guide; Constitution Art 19(1)(a), Art 21; SC decisions 2002-2024.

All ten rulings read the Act's exemptions through Section 8 and its §8(2) public-interest override.

• Puttaswamy (2017) — Privacy is fundamental but not absolute; legality, legitimate aim, proportionality.
• Girish Deshpande (2013) — Section 8(1)(j) protects a public servant's service record; disclosure only on larger public interest.
• R.K. Jain (2013) — Notings integral to an officer's ACR are personal information; §11 third-party notice is mandatory.
• Subhash Chandra Agarwal (2019, reported 2020) — CJI's office is a public authority; public-interest balancing applies.
• Jayantilal Mistry (2016) — RBI inspection reports disclosable; fiduciary exemption read narrow.
• Aditya Bandopadhyay (2011) — Evaluated answer books are “information”; no fiduciary bar; no re-evaluation via RTI.
• Thalappalam (2013) — Cooperatives + scope of “public authority”.
• Electoral Bonds case (2024) — Voter's right to know extends to political funding.
• Khanapuram Gandaiah (2010) — Copies of orders and opinions yes; the reasons “why” no.
• PUCL / ADR election line (2002-2003) — Voters' right to know candidates' antecedents.

1. Identify the question category — Disclosure standard? Exemption scope? Public interest? Procedural?
2. Match to top SC rulings — Each ruling has its own factual context — match analogous facts.
3. Cite ratio (binding portion) not obiter (commentary) — Three-line citation per case is enough; full text only on second appeal.
4. Use as decision support — A PIO order citing the right SC ruling holds up better in first appeal.
5. For FAA: use to overturn unjustified PIO denials — SC rulings bind the FAA too; it can distinguish on facts but not ignore them. More in the PIO-FAA knowledge base.

KEY SC RULINGS PIO + FAA SHOULD CITE:

1. K.S. PUTTASWAMY v UNION OF INDIA — (2017) 10 SCC 1
   Holds: Privacy is a fundamental right, but not absolute. Any invasion must satisfy legality, legitimate aim and proportionality.
   When to cite: personal-data queries where §8(1)(j) and privacy collide.

2. GIRISH RAMCHANDRA DESHPANDE v CENTRAL INFORMATION COMMISSIONER — (2013) 1 SCC 212
   Holds: A public servant's service record — APAR/ACR, GP Fund, disciplinary material, assets beyond mandated disclosure — is third-party "personal information", exempt under §8(1)(j) unless the applicant shows larger public interest under §8(2).
   When to cite: requests for a public servant's service record, APAR, assets or family details.

3. R.K. JAIN v UNION OF INDIA — (2013) 14 SCC 794
   Holds: File notings that form an integral part of an officer's ACR are personal information under §8(1)(j); disclosure was denied absent larger public interest. §11 third-party notice is mandatory.
   When to cite: ACR-linked notings, third-party personal records.

4. CPIO, SUPREME COURT OF INDIA v SUBHASH CHANDRA AGARWAL — (2020) 5 SCC 481 (Constitution Bench, decided 13 November 2019)
   Holds: The CJI's office is a public authority under the RTI Act; judicial independence does not oust the Act. Judges' asset and collegium information goes through §8(1)(j)/§8(2) public-interest balancing.
   When to cite: judicial appointment, judicial conduct, judges' assets queries.

5. RBI v JAYANTILAL N. MISTRY — (2016) 3 SCC 525
   Holds: §8(1)(e) fiduciary relationship is narrow. RBI cannot withhold banks' inspection/annual financial inspection reports; it has a statutory duty to disclose.
   When to cite: regulator inspection, financial-institution queries.

6. CBSE v ADITYA BANDOPADHYAY — (2011) 8 SCC 497
   Holds: Evaluated answer books are "information" under §2(f); the examiner-Board relationship is not fiduciary under §8(1)(e). RTI gives inspection or certified copies — not re-evaluation.
   When to cite: education, examination, scholarship queries.

7. THALAPPALAM SERVICE COOP BANK v STATE OF KERALA — (2013) 16 SCC 82
   Holds: Cooperative societies are NOT "public authorities" under §2(h) unless substantially financed by govt.
   When to cite: queries about cooperatives, NGOs, private bodies.

8. ADR v UNION OF INDIA — ELECTORAL BONDS DECISION, 2024
   Holds: The electoral bonds scheme was struck down as unconstitutional; the voter's right to information about political funding prevails.
   When to cite: political funding, party finance queries.

9. KHANAPURAM GANDAIAH v ADMINISTRATIVE OFFICER — (2010) 2 SCC 1
   Holds: An applicant can obtain copies of opinions, advices, circulars and orders, but cannot demand to know WHY they were passed — especially in judicial and quasi-judicial matters.
   When to cite: queries seeking the reasons or opinion behind a decision.

10. PUCL v UNION OF INDIA — (2003) 4 SCC 399 (building on ADR v Union of India, 2002)
    Holds: Voters have a fundamental right to know the antecedents of candidates — criminal record, assets, education.
    When to cite: ECI, candidate disclosure, MP/MLA election queries.

Cite CBSE v Aditya Bandopadhyay — evaluated answer books are “information” under §2(f); the examiner-Board link is not fiduciary under §8(1)(e). RTI gives inspection or certified copies, not re-evaluation.

Cite Girish Deshpande — service records, APARs and assets beyond mandated disclosure are third-party personal information, exempt under §8(1)(j) unless the applicant shows larger public interest under §8(2).

Cite R.K. Jain — notings that form an integral part of the ACR are exempt personal information; give the third party a §11 notice before deciding.

Cite RBI v Jayantilal Mistry — fiduciary read narrow; banking regulator inspection reports disclosable.

Cite CPIO, Supreme Court of India v Subhash Chandra Agarwal — CJI's office covered; public-interest balancing applies.

• K.S. Puttaswamy v Union of India (SC 2017) — privacy not absolute; the proportionality test now shapes §8(1)(j) analysis.
• Girish Ramchandra Deshpande v Central Information Commissioner (SC 2013) — the most-cited authority for withholding service records absent larger public interest.
• R.K. Jain v Union of India (SC 2013) — ACR-linked notings; §11 third-party procedure mandatory.
• RBI v Jayantilal Mistry (SC 2016) — fiduciary narrow; regulator transparency.
• CPIO, Supreme Court of India v Subhash Chandra Agarwal (SC 2019) — judicial accountability; public-interest balancing.
• The RTI Playbook

• Citing wrong rulings — e.g., citing CBSE v Aditya Bandopadhyay for tenders; it is the exam answer-books case.
• Reversing Girish Deshpande — it supports withholding service records under §8(1)(j) unless larger public interest is shown; it does not order disclosure.
• Citing CIC orders as if SC binding — they bind the parties before them, no more; SC and High Court rulings bind.
• Quoting obiter (commentary) rather than ratio (binding).
• Treating SC rulings as PIO defense — they're neutral; can support either side.
• Citing without dates — e.g., “SC ruling on RTI” without case name.
• Failing to follow updates — DPDP §44(3) (2023) modifies parts of pre-2023 §8(1)(j) interpretation.

• Maintain a personal “ruling library” — top 10 above + 5-7 specific to your subject area.
• Cite the ratio in 1-2 lines; full text saved for IC if needed — see how to cite case law in an RTI reply.
• For each ruling, note the specific SC paragraph that contains the ratio — easier to defend.
• Update annually — SC may issue new rulings that modify previous holdings.
• For complex queries spanning multiple rulings, build a layered citation.
• Train new PIOs on these 10 cases — accelerates their decision-making.

They bind the parties before them but set no precedent — SC and High Court rulings bind. High Court RTI rulings for PIOs covers that layer.

FAA cannot depart from SC ruling. Can only distinguish facts (different from ruling) — must give reasons.

Partially — §44(3) amends §8(1)(j) to protect personal data covered by the DPDP Act 2023. The Girish Deshpande line still governs service-record queries in practice.

Use this list as starting point; the CIC website hosts a searchable database of its decisions.

Mostly statutory — timelines sit in §7 of the Act itself; the CIC decision database covers the rest.
