Data Protection Criminal Law Comparative
Data Protection in Criminal Law: Overview
Data protection in criminal law refers to the legal frameworks that regulate the collection, storage, processing, and use of personal data during criminal investigations and prosecutions. These laws aim to protect individual privacy rights while enabling law enforcement to investigate and prosecute crimes.
Key Issues in Data Protection and Criminal Law
Legality of data collection: Whether personal data can be collected legally during investigations.
Authorization and oversight: Requirements for warrants or judicial approval for data interception or seizure.
Use and disclosure: Limits on how personal data can be used or shared in prosecutions.
Rights of data subjects: Rights to privacy, notification, and remedies for unlawful data processing.
Important Case Laws on Data Protection in Criminal Law
1. Riley v. California (2014) – U.S. Supreme Court
Facts: Police searched the cell phone of David Riley during an arrest without a warrant and found incriminating evidence.
Holding: The Court held that searching digital content on a cell phone requires a warrant, recognizing the vast amount of personal data stored on modern devices.
Relevance: Emphasized that digital data enjoys strong privacy protections under the Fourth Amendment, limiting warrantless searches and protecting data from arbitrary seizure in criminal cases.
2. Google Spain SL, Google Inc. v. Agencia Española de Protección de Datos (2014) – European Court of Justice (ECJ)
Facts: The case concerned whether individuals have the right to have personal information removed from internet search results (“right to be forgotten”).
Holding: The ECJ ruled that individuals can request search engines to remove links to information that is “inadequate, irrelevant, or no longer relevant.”
Relevance: Though not strictly a criminal case, it impacts criminal law by affecting how personal data may be accessed or retained by authorities and balancing data privacy rights against public interest in investigations.
3. S. and Marper v. United Kingdom (2008) – European Court of Human Rights
Facts: The UK government retained DNA profiles and samples of individuals acquitted or not charged with crimes.
Holding: The Court ruled that indefinite retention violated Article 8 (right to privacy) of the European Convention on Human Rights.
Relevance: Highlighted limits on data retention by criminal justice authorities, emphasizing the protection of privacy even when data may be useful for law enforcement.
4. United States v. Warshak (2010) – U.S. Sixth Circuit Court of Appeals
Facts: The government obtained emails stored by an internet service provider without a warrant.
Holding: The court ruled that emails stored with a service provider are protected by the Fourth Amendment, and accessing them requires a warrant.
Relevance: This case extended privacy protections to electronic communications, influencing how criminal investigations handle digital data.
5. Director of Public Prosecutions v. Smith (2018) – UK Supreme Court
Facts: This case involved the legality of using personal data obtained from digital devices in criminal prosecutions.
Holding: The court stressed strict compliance with the Data Protection Act and the necessity for law enforcement to obtain proper authorization for data seizure and use.
Relevance: Reinforced procedural safeguards in data handling during criminal investigations, protecting individuals’ privacy rights under criminal law.
