This book on practice and procedure of courts at the Apex level of Hierarchy, is generally conceived to be a practitioners guide, a ready reckoner, a condensed digest of case law, hand and useful for examinations, or a text book or as a quick glance for locating precedents. When this book was initially thought about, the idea was to produce a book closely fitting in with the above. However, as the book progressed, it occurred that some fundamental jurisprudential elements of the functioning of the Supreme Court need to be drawn and elucidated.
