Constitution of India, 1950 — Article 21 – Liberty of a person under trial – “bail or jail ?”.
“8. It is thus obvious that the nature of the charge is the vital factor and the nature of the evidence also is pertinent. The punishment to which the party may be liable, if convicted or conviction is confirmed, also bears upon the issue.
9. Another relevant factor is as to whether the course of justice would be thwarted by him who seeks the benignant jurisdiction of the Court to be freed for the time being.
10. Thus the legal principles and practice validate the Court considering the likelihood of the applicant interfering with witnesses for the prosecution or otherwise polluting the process of justice. It is not only traditional but rational, in this context, to enquire into the antecedents of a man who is applying for bail to find whether he has a bad record – particularly a record which suggests that he is likely to commit serious offences while on bail. In regard to habituals, it is part of criminological history that a thoughtless bail order has enabled the bailee to exploit the opportunity to inflict further about the criminal record of a defendant, is therefore not an exercise in irrelevance.”
