Philosophy of BAIL was discussed by this Court in Vaman Narain Ghiya v. State of Rajasthan, (2009) 2 SCC 281, thus:
“BAIL” remains an undefined term in Code of Criminal Procedure. Nowhere else has the term been statutorily defined. Conceptually, it continues to be understood as a right for assertion of freedom against the State imposing restraints. Since the UN Declaration of Human Rights of 1948, to which India is a signatory, the concept of BAIL has found a place within the scope of human rights. The dictionary meaning of the expression “BAIL” denotes a security for appearance of a prisoner for his release. Etymologically, the word is derived from an old French verb “Bailer” which means to “give” or “to deliver”, although another view is that its derivation is from the Latin term “baiulare”, meaning “to bear a burden”. BAIL is a conditional liberty. Stroud’s Judicial Dictionary (4th Edn., 1971) spells out certain other details. It states:
…when a man is taken or arrested for felony, suspicion of felony, indicted of felony, or any such case, so that he is restrained of his liberty. And, being by law Bailable, offereth surety to those which have authority to BAIL him, which sureties are bound for him to the King’s use in a certain sums of money, or body for body, that he shall appear before the justices of goal delivery at the next sessions, etc. Then upon the bonds of these sureties, as is aforesaid, he is BAILed-that is to say, set at liberty until the day appointed for his appearance.
BAIL may thus be regarded as a mechanism whereby the State devolutes upon the community the function of securing the presence of the prisoners, and at the same time involves participation of the community in administration of justice.
Personal liberty is fundamental and can be circumscribed only by some process sanctioned by law. Liberty of a citizen is undoubtedly important but this is to balance with the security of the community. A balance is required to be maintained between the personal liberty of the accused and the investigational right of the police. It must result in minimum interference with the personal liberty of the accused and the right of the police to investigate the case. It has to dovetail two conflicting demands, namely, on the one hand the requirements of the society for being shielded from the hazards of being exposed to the misadventures of a person alleged to have committed a crime; and on the other, the fundamental canon of criminal jurisprudence viz. the presumption of innocence of an accused till he is found guilty. Liberty exists in proportion to wholesome restraint, the more restraint on others to keep off from us, the more liberty we have. (A.K. Gopalan v. State of Madras)
The law of BAIL, like any other branch of law, has its own philosophy, and occupies an important place in the administration of justice and the concept of BAIL emerges from the conflict between the police power to restrict liberty of a man who is alleged to have committed a crime, and presumption of innocence in favour of the alleged criminal. An accused is not detained in custody with the object of punishing him on the assumption of his guilt.
