Based on the provided legal document, the key points regarding the issue of whether an accused summoned by bailable warrant can be sent to jail or should remain on bail until the conclusion of the trial are as follows:

1. The issuance of a bailable warrant primarily aims to secure the presence and attendance of the accused before the court. Once the accused appears in response to the bailable warrant and continues to attend all subsequent proceedings, the court generally should not send him to jail without a valid supervening reason (!) (!) .

2. The act of summoning an accused by a bailable warrant in a non-bailable offence is a conscious and deliberate decision by the court, indicating an intention to secure his appearance without necessarily implying that bail has been granted or that the accused is in custody (!) (!) .

3. When an accused appears before the court in response to a bailable warrant and has furnished bail bonds and sureties, he is considered to be in symbolic custody and has a right to continue on bail until the trial concludes, unless there are specific reasons such as violation of bail conditions, absconding, or other supervening circumstances that justify sending him to jail (!) (!) .

4. The court must exercise its discretion judiciously and with due application of mind when deciding to send an accused to jail after response to a bailable warrant. Such action should be based on valid reasons, including non-compliance with bail conditions or other conduct that undermines the court's authority or the integrity of the trial process (!) (!) .

5. The legal framework recognizes that once an accused appears and continues to attend court proceedings, the issuance of a bailable warrant does not automatically translate into a grant of bail. The accused has the right to apply for regular bail, and the court should consider such applications on their merits, respecting the principles of fairness and personal liberty (!) (!) .

6. Any decision to send an accused to jail at a later stage, after initial appearance on a bailable warrant, must be made with proper notice, an opportunity to be heard, and based on concrete, justifiable reasons. Arbitrary or mechanical actions are not permissible, and such actions would violate the constitutional guarantee of personal liberty (!) (!) .

7. The procedural provisions and judicial principles emphasize that the liberty of the individual is paramount, and courts should avoid unnecessary detention. The decision to incarcerate an accused summoned by a bailable warrant should be taken only after careful consideration of all relevant circumstances, ensuring adherence to constitutional rights and due process (!) (!) .

In summary, the legal position strongly favors allowing an accused summoned by a bailable warrant to remain on bail until the trial's conclusion, provided he continues to comply with court directions and does not engage in conduct warranting detention. Any deviation from this principle requires clear, valid reasons and adherence to procedural fairness.
