CAC to pick the head coach but the selection committee's say matters in hiring supporting staff.
Sachin filed a 14-point written response to a notice.
Earlier, Ganguly was also served a similar notice to explain his position and association with the DC team.
“No one sacked Kumble." - VVS Laxman.
Shastri was appointed coach in July 2017 after Anil Kumble resigned from the top job.
The new selection committee will now pick the U19 squad for a quadrangular tournament in Kolkata which will begin on September 9 and for U19 Asia Cup as well.
Normally, the national team selectors are given a one-year contract until the next Annual General Body meeting.
Ganguly hopes to settle the issue with his former teammate when Sehwag travels to Kolkata for commentating in the second ODI between India and Australia.
Sehwag mentioned that Ganguly didn't need to provide any justification to anyone, as he knows what's true.
Sehwag said he had even asked Shastri why he hadn’t applied for the role during Champions Trophy in England.
