The Prime Minister's Office (PMO) has refused to share details on the quantum of black money brought back from abroad, citing a provision of the RTI Act that bars disclosure of information that may impede investigation and prosecution of offenders. Its response came on an October 16 order passed by the Central Information Commission, asking the PMO to provide details of black money within 15 days. Replying to an RTI query, the PMO said a Special Investigation Team (SIT) has already been formed and its investigation is underway. \u201cAs such, disclosure of all the action\/efforts undertaken by the government at this juncture may impede the whole process of investigation or apprehension or prosecution of offenders and hence would attract the provision of exemption under Section 8 (1) (h) of the RTI Act,\u201d it said in response to the RTI application filed by whistleblower bureaucrat Sanjiv Chaturvedi. Such investigations come under the purview of different government intelligence and security organisations which have been excluded from the ambit of the RTI Act, the PMO said.

In its initial reply to the RTI application, the Prime Minister's Office had in October last year said the query was not covered under Section 2(f) of the transparency law that defines information. Chaturvedi thereafter moved the Central Information Commission which had last month ordered the PMO to provide information within 15 days. There is, at present, no official assessment on the quantum of black money in India and abroad. According to a study by US-based think-tank Global Financial Integrity (GFI), an estimated USD 770 billion in black money entered India during 2005-2014.
