The document summarizes the case A.K. Kraipak v. Union of India, AIR 1970 SC 150. It discusses that:
1) The case involved the selection of officers to the Indian Forest Service, where one of the selection board members (Naquishbund) was also a candidate for selection.
2) The court held this violated the principle of natural justice that "no one can be a judge in their own case," as Naquishbund's presence on the board created a conflict of interest and likelihood of bias.
3) The Supreme Court decided that principles of natural justice apply not just to judicial functions but also administrative functions like government service selection boards.
