Karnataka RDPR — beejadi gram panchayat given permission to construct a house when ownership of the property with 3 people without my signature

Dear sir/madam,
This is with regard to above mention subject, rtc is in the name of 3 brothers, myself veerabhadra, chandrashekar and subramanya. I have refused to sign and when my brother chandrashekar who is constructing house asked for aadhar card copy i told him once the partition is done you can go ahead and construct the house for doing partition deed they agreed will do it after 2months, and i agreed and since 5 years i am requesting them do the partition giving one or the other answers and postponing the procedure. I gave legal notice and gave 2 months time this period ends on 22nd december 2018. Meanwhile without my consent he started 2nd brother started building a house (3rd brother and contractor took permission) because me and my brother are in bangalore. I was not aware that he started building house it is already 15 days over as soon i came to know i sent objection letter gram panchayat beejadi, along with necessary proof, on 30th november 2018. When i asked when the construction will be stoped they say it will be discussed in meeting, when i asked when the meeting will be held, they are saying date not fixed, another person says you have the right and you can go and stay, instead of stopping the construction.
The concerned authorities please look into this because this requires immediate action, i heard that till roof level the construction work is done they started laying slabs.
I hope action will be taken immediately.
Thanks with regards,
Veerabhadra
