Certainly. Based on the provided legal document, the key legal principles regarding the cancellation of bail are as follows:

1. Supervening Circumstances: Cancellation of bail requires cogent and overwhelming supervening circumstances. A mere registration of a subsequent crime against the accused does not automatically justify bail cancellation unless it significantly affects the conduct of a fair trial or indicates misuse of liberty (!) (!) (!) (!) (!) .

2. Distinction Between Initial Rejection and Cancellation of Bail: The legal standards for rejecting bail at the initial stage differ from those for cancelling an already granted bail. Cancellation must be based on a careful assessment of supervening circumstances and cannot be done mechanically (!) (!) (!) .

3. Assessment of Interference with Trial: The court must evaluate whether the subsequent involvement in a new crime interferes with the fair conduct of the trial of the original case. If the new allegations do not impact the trial proceedings or the administration of justice, bail should not be cancelled solely on that basis (!) (!) (!) .

4. Nature of the Crime and Its Effect: The nature and gravity of the subsequent crime are relevant. The court should consider whether the new offence indicates misuse of liberty, attempts to influence witnesses, or other conduct that hampers justice. However, involvement in subsequent crimes alone is not sufficient unless it affects the trial or indicates a pattern of misconduct (!) (!) .

5. Procedural Due Process: Before cancelling bail, courts are required to conduct a summary enquiry, reviewing records and allegations, and providing an opportunity for the accused to be heard. The decision should be reasoned, and mechanical cancellation without proper scrutiny is not permissible (!) (!) (!) .

6. Bail as a Rule and Jail as an Exception: The fundamental principle is that bail is the rule, and detention is the exception. Therefore, very strong and clear reasons are necessary to deprive an accused of liberty once bail has been granted (!) (!) (!) .

7. Misuse of Liberty and Conditions of Bail: Violation of bail conditions, such as involvement in another crime, may be a ground for cancellation if it demonstrates misuse of liberty or interference with justice. Nonetheless, each case must be scrutinized individually to determine whether the involvement in a subsequent crime constitutes a supervening circumstance warranting cancellation (!) (!) (!) .

8. Time Gap and Pattern of Crime: The time elapsed between the original offence and the subsequent involvement is relevant. A significant gap may suggest that involvement in a subsequent crime does not automatically impact the original trial or justify bail cancellation unless linked to conduct affecting justice (!) (!) .

9. Judicial Discretion and Mechanical Orders: Courts must exercise their discretion judiciously, and bail should not be cancelled in a mechanical manner. Proper reasoning and consideration of all relevant factors, including the nature of the offences and the conduct of the accused, are essential (!) (!) (!) .

10. Preventive Measures: The legal provisions for preventive detention are separate, and the power to cancel bail does not substitute for statutory preventive detention laws. If there is a concern about repeated offences or misuse of liberty, appropriate statutory procedures should be followed (!) (!) .

In summary, the cancellation of bail is a serious judicial act that requires compelling reasons, a thorough assessment of circumstances, and adherence to procedural fairness. It cannot be based solely on the registration of a new crime or the involvement in subsequent offences without demonstrating that such involvement adversely impacts the trial process or indicates misuse of liberty.
