How has the SC strengthened arrest safeguards? | Explained

The story so far:

The Supreme Court recently, in Jaskaran Jeet Singh Deol v. State of Punjab (September 2026), held that the investigating agency would require permission of the magistrate to re-arrest the accused after his previous arrest was held illegal for the non-supply of the grounds of arrest in writing. It also recommended departmental action for the negligent investigating officer (IO) and change of the IO in the case.
