The Act provides that a person shall be eligible for election as a member of a Panchayat if he/she is a citizen of India, has completed the age of 21 years on the date of nomination, is not a member of any other local authority, is not an undischarged insolvent, is not a person of unsound mind and is not a person who has been convicted of an offence and sentenced to imprisonment for two years or more.
