ESSENTIALS OF AFFAIR OF STATE
When we talk about practicality of sec. 123 a very logical query arises, when the court finds that the document in question relates to any affair of State, it will then be for the departmental head to decide whether disclosure of its contents would be against public interest and his decision on the point is conducive.
