A constitution bench of Apex Court held as follows:

From Para 59,

59. Reading of the aforesaid judicial precedents, in our opinion, would indicate that personal records, including name, address, physical, mental and psychological status, marks obtained, grades and answer sheets, are all treated as personal information. Similarly, professional records, including qualification, performance, evaluation reports, ACRs, disciplinary proceedings, etc. are all personal information. Medical records, treatment, choice of
medicine, list of hospitals and doctors visited, findings recorded, including that of the family members, information relating to assets, liabilities, income tax returns, details of investments, lending and borrowing, etc. are personal information. Such personal information is entitled to protection from unwarranted invasion of privacy and conditional access is available when stipulation of larger public interest is satisfied. This list is indicative and not exhaustive.
