Common questions
Why does the same kind of violation lead to different outcomes across jurisdictions?+
The US treats exclusion as a near-automatic deterrent against unlawful searches, while England and Wales leaves it to judicial discretion weighing fairness, and India generally admits improperly obtained evidence unless a specific statutory bar applies, reflecting different constitutional priorities.
Can improperly seized digital evidence still be used in a discretionary jurisdiction?+
Often yes. Under a discretionary approach like PACE s.78, a court can admit the evidence if excluding it would be more unfair to the proceedings than the manner of its collection, unlike the near-automatic exclusion applied in the US.
