About Gram Nyayalayas

• Article 39A of the Indian Constitution ensures that the legal system promotes justice and provides free legal aid to ensure equal opportunities for all citizens, regardless of economic or other disabilities.

• This vision was realised with the passage of the Gram Nyayalayas Bill in 2008, and the subsequent implementation of the Gram Nyayalayas Act, in 2009.

• Gram Nyayalayas are deemed to be a Court of Judicial Magistrate of First Class with both civil and criminal jurisdiction to settle petty disputes at the village level.

• The Act extends to the whole of India, excluding Nagaland, Arunachal Pradesh, Sikkim, and certain tribal areas in Assam, Meghalaya, Tripura, and Mizoram. 

• While not bound by the rules of evidence in the Indian Evidence Act, 1872 (replaced by Bharatiya Sakshya Adhiniyam), Gram Nyayalayas follow principles of natural justice as guided by the High Court rules. 

Hence option 3rd is correct.
