The above power of the President & the Governor is not subject to the approval of Union or state Cabinet. It is the constitutional power of the said posts. As it is a democratic country, President & Governor shared the power with their cabinet.

Can President/Governer bye pass the Union/State Cabinet to decide a mercy petition ?

this is slightly off topic answer..

In a recent decision titled Narayan Dutt Vs St. of Punjab the Hon'ble Apex court has given some pointers/guidelins in dealing with pardon by Guv/Pres.. may be of interest to you [2011(4) SCC 353 dt 24/2/2011]

By the way this is executive power and cannot be subject to cabinet (legislature)

No Mercy Petitions are not subject to the approval of Uno\ion Cabinet, on the executive head of the state or the country has the power to deal with it.  

agreed with mr democratic union.

president not bound to follow it but if she desires to follow nothing can restrict her.

normally it is a healthy situation for a democratic country.

mr rajkumar raised a good point.

like to know the guideline of sc  - if possible.

today president rejects two perdon petition.

Rather it is a real unhealthy situation for a democracy because usually the people who are greatest yesmen and greatest chamchas of the ruling party are appointed in "rewarding" posts of President or Governors. Hence rarely these people have any personality of their own, therefore in 99.99% of the cases they blindly follow the desires of the cabinet/ruling party. This is the most unfortunate fact of our glorious democracy.

yes mr democratic union, you are right.

the people has also mind.

they apply their mind also.

therefore everything known to them.

but in want of perfect alternative, they can't do any drastic or appropriate action.

" This is the most unfortunate fact of our glorious democracy. "

------      yes, right.

but we can not go out from this society. whatever we think right for our society, we have to obtain it through this system. our brain exercise for this purpose only.
