What things required to get bail ?

The Supreme Court of India enforced this right to due process and the right against arbitrary arrest in Joginder Kumar Vs State of UP in 1994.  This judgment explicitly states that:

“No arrest can be made because it is lawful for the police officer to do so. The existence of the power to arrest is one thing. The justification for the exercise of it is quite another. The police officer must be able to justify the arrest apart from his power to do so. Arrest and detention in police lock-up of a person cause incalculable harm to the reputation and self-esteem of a person. No arrest can be made in a routine manner on a mere allegation of commission of an offence made against a person. It would be prudent for a police officer in the interest of protection of the constitutional rights of a citizen and perhaps in his own interest that no arrest should be made without a reasonable satisfaction reached after some investigation as to the genuineness and bona fides of a complaint and a reasonable belief both as to the person’s complicity and even so as to the need to effect arrest. Denying a person of his liberty is a serious matter.“
