There are two types of Bail; one is anticipatory and another one is regular.

Any person of 18 years and above can become a Surety. However, accepting and rejecting a Surety depends on the Court and the Court has complete privilege. Only the Court under whose Order the Surety is being given has the powers to modify and relax the terms and conditions imposed on it.

Surety is one who stands as Guarantor. In Criminal Laws, the private person who stands as a Guarantor and who appears in the Court, executes a Bond [for certain amount prescribed by the Court for the release of the Accused] and performs the process of suretyship is called Surety.

As far as the Bail and Bonds are concerned the Court that grants Bail has the power to cancel the Bail / Surety for change in circumstances.    

The Bail would sustains on the Accused as long as the Court is convinced that there was no breach of its conditions. Sometimes, change in circumstances compels the Court to cancel the Bail.

Bail is a transfer of temporary custody of Accused from the Court to the Private Person who volunteers himself / herself to take responsibility of producing the Accused when the Court requires him or the Police needs him under the Law.

Those Witnesses arrayed in the Chargesheet and lined-up by the Police for taking Chief Examination of the Court are called Prosecution Witnesses.

The Chief Examination is the first Stage of examination of the Witness and upon every Witnesses were examined in Chief, the Court gives an opportunity to the Accused for crossing them.  Without Chief, Cross cannot be done and without Chief and Cross, Re-examination can never happen.   Chief Examination: The Court record statements of the Witnesses[…..]

Prosecution is part and parcel of the Judiciary. It is an interface between the Police and the Court. Otherwise, the Criminal Laws restricts Police to address directly to the Court [only if required to be, they are allowed to address for limited purpose, just to an extent of clarifications] and it has no legal powers[…..]

Prosecution begins the Case in the Court immediately after the Accused repudiated the crime when questions raised by the Trial Court under Section 313 of Cr.P.C.
