The Centre had declared as "unconstitutional and illegal" the constitution of Commission of Inquiry into the DDCA affairs by the AAP dispensation in Delhi in the continuing battle between the two governments.
The rejection of the Delhi government's decision to probe the affairs of Delhi and District Cricket Association (DDCA) comes on top of a bitter fight between the Arvind Kejriwal-led AAP government and the Centre after the raid on the Delhi Secretariat a month ago.
The raid had led to a confrontation between the two with Kejriwal alleging that it was meant to seize some files purportedly containing details of alleged corruption in DDCA when Jaitley was its president between 1999 and 2013.
Kejriwal followed up his charge by his government's decision to constitute a probe under the Commission of Inquiry Act headed by former Solicitor General Gopal Subramanium, who has contended that Delhi government has the authority to constitute such a probe which he would go ahead with.
