Download Lien means the title of a Government servant to hold substantively, either immediately or on the termination of a period or periods of absence, a permanent post, including a tenure post, to which he has been appointed substantively. A Government servant cannot be appointed substantively to a post on which another Government servant holds a lien. Unless in any case, it be otherwise provided in these rules, a Government servant on substantive appointment to any permanent post acquires a lien on that post and cases to hold any lien previously acquired on any other post.
