Fsi approval by gram panchayat

Hello Experts,

I wanted to know who is the sanction authority for FSI approval and building plan approval for Gram Panchyat in Maharashtra. I found their is no fixed rule for this as its not coming under town planning. Few Gram Panchayats are approving 1.5 FSI and few are approving 1 .... that to in same city.

How much is the FSI we can get for the land under Gram Panchayat?

Can anyone pls let me know how the process and sanctions work??

Regards;
