- Bench
- Justices Arun Mishra, Indira Banerjee, Vineet Saran, M.R. Shah and S. Ravindra Bhat (Constitution Bench)

The reference was answered accordingly, and the petitions were directed to be placed before the appropriate Court for decision on merits in light of the answer (paras 12-14).
Key holdings
- Merely because the informant is the investigator, the investigation does not suffer from unfairness or bias, and the accused is not entitled to acquittal on that sole ground (para 12).
- Mohan Lal v. State of Punjab, (2018) 17 SCC 627, and any decision holding that the informant cannot be the investigator are not good law and are overruled (para 12).
- Bhagwan Singh, Megha Singh and Rajangam are confined to their own facts and lay down no general rule (paras 8, 12).
- Neither the CrPC nor the NDPS Act bars the informant from investigating; Section 53 of the NDPS Act permits it (paras 9.1, 9.5, 11).
- Bias or prejudice has to be established, not inferred; if proved where the case rests only on the informant-investigator, it can be given due weightage (para 11).
