The AIADMK has amended its bylaws mandating a minimum of five years uninterrupted membership in the party to contest for all posts, including top positions of coordinator and co-coordinator.
The change was made at the party's general council and executive committee meet held on Sunday, 24 November, according to party sources.
The move is perceived as an attempt to foreclose the possibility of VK Sasikala, aide of late Chief Minister J Jayalalithaa, or her relatives from trying to assume party posts.
