Why doesn’t TRAI have to explain their actions

Could this “fee” being imposed, be, to make up for the shortfall in funds since they want to move to 74% FDI only, to make up the remaining 26% ??
It’s very strange, what TRAI has recommended, almost like someone from BSNL/MTNL put a gun to their heads and said…
Now sing!
:O

Freedom of information etc.
