Personal liberty is one of the most basic and vital aspects pertaining to human rights. A man by birth have certain inalienable rights, of them, right to life, liberty and property are sacrosanct. This implies that an unreasonable, unjust and unfair procedure cannot be permitted to usurp personal liberty of an individual even if it be sanctified by the legislature in the form of a law. Thus, personal liberty of an individual cannot be taken away unless a validly enacted law authorises it. The procedure adopted by law must be reasonable, just and fair.This book deals with the law of bail, bonds, arrest and custody at length. Bail is a mechanism by which the adverse consequences of delay before trial can be minimised. The attempt in this edition has been to not only arrange the whole law on the subject so as to render perspicuity to it but the labour has been to expound the reasons and to lay before the reader the basis on which the decisions have proceeded. Attention has been devoted to render the work practically useful. It unfolds minutely the nature of the law of bails, the principles on which it is founded, and the practical rules connected with its administration to facilitate the readers understand the basic nuances of the law. Most recent judicial decisions of Supreme Court and High Courts have been added in good measure.The book will be useful for the members of the Bench, the bar, the prosecuting agencies, the investigating agencies and others interested in the subject.
