At Nandan's funeral, Koppulingam receives a phone call announcing the village panchayat's conversion to a reserved constituency, rendering him ineligible to contest.

Concealing this fact, Koppulingam deceitfully announces his willingness to allow an SC candidate, exploiting the situation to maintain control.

Seeking justice, Koozhpaana meets the Block Development Officer (BDO) Marudhudurai, who allocates 10 cents of government land for a cremation ground which appears to be encroached by Koppulingam.

The movie concludes with Koozhpaana aka Ambedkumar making his first signature sitting in the village president's chair which was refused earlier.

[11] Gopinath Rajendran of The Hindu wrote "Despite focusing on a pertinent issue that needs immediate attention and holding up a mirror to society on caste oppression and power dynamics, Sasikumar and Era Saravanan’s Nandhan suffers from shallow writing and amateurish making.

"[13] Roopa Radhakrishnan of The Times of India rated two point five out of five and wrote that "All in all, Nandhan is a film with good intent made on a serious subject that has its moments, especially on the comedy front"[14]
