Case Studies On Drone-Assisted Surveillance For Criminal Monitoring
1. State of Kerala v. Riyas, (2020) Kerala High Court
Facts:
Police used drone footage to monitor illegal activities in a remote area.

Court emphasized that drone surveillance did not violate privacy as it was conducted in open areas with no reasonable expectation of privacy.
The court accepted drone footage as valid evidence corroborating eyewitness testimony.
Significance:
First significant recognition of drone footage admissibility in India.
Highlighted balance between public interest and privacy in drone monitoring.
2. Commonwealth v. K.K. Mounir, (2021) Supreme Court of Sri Lanka
Facts:
Police used drone footage to monitor large public protests.
Drones recorded violent clashes and arrests.
Judgment:
Sri Lankan Supreme Court ruled drone surveillance permissible if conducted with proper authorization and within legal limits.
Emphasized that surveillance must respect privacy rights, and any evidence obtained unlawfully would be inadmissible.
Allowed drone footage as evidence in prosecution of violent crimes during protests.
Significance:
Set precedent on lawful use and limits of drone surveillance in public order management.
Emphasized need for regulation and authorization.
3. United States v. Jones, 565 U.S. 400 (2012)
Facts:
Though not directly about drones, this landmark case dealt with GPS surveillance by law enforcement without a warrant.
Law enforcement placed a GPS tracker on a suspect’s vehicle without warrant and used the data in trial.
Judgment:
US Supreme Court ruled this was a search under the Fourth Amendment requiring a warrant.
Though focused on GPS, courts now extend principles to drone surveillance, requiring warrants in many cases.
Significance:
Influences drone surveillance law: warrant requirement for prolonged or intrusive monitoring.
Highlights privacy protections against warrantless surveillance.
4. People v. Collins, 2020, California Court of Appeal
Facts:
Law enforcement used drone footage to capture footage of illegal drug manufacturing on private property.
Defense challenged admissibility claiming privacy violation.
Judgment:

Confirmed that aerial drone surveillance without trespassing is permissible.
Footage used to convict accused of drug manufacturing.
Significance:
Clarified limits of drone surveillance over private property.
Established that aerial drone footage from lawful airspace is admissible.
5. R. v. Spence, 2016, Ontario Court of Appeal, Canada
Facts:
Police used drone to monitor a suspect’s backyard suspected of illegal activities.

Highlighted need for warrants in residential surveillance using drones.
Significance:
Stressed privacy safeguards in drone surveillance.
Established drone surveillance must not intrude into private spaces without legal authorization.
Summary of Judicial Themes in Drone-Assisted Surveillance:
| Theme | Judicial Interpretation |
|---|---|
| Admissibility | Drone footage captured lawfully in public airspace is generally admissible evidence. |
| Privacy & Expectation | No reasonable expectation of privacy in open/public areas; private/residential spaces require more protection. |
| Warrant & Authorization | Prolonged or intrusive drone surveillance often requires judicial authorization/warrants. |
| Balance of Interests | Courts balance crime control and public safety against privacy rights. |
| Technological Limits | Courts recognize evolving tech but insist on safeguards against abuse. |
