On 13 April 2023, the Korean Supreme Court issued a decision ordering Google to disclose the list of personal information it has shared with third parties, including United States intelligence services. The Supreme Court stated that in cases where personal information was provided to foreign intelligence agencies for probable cause, the service provider is still required to tell customers when that cause terminates. Under the Korean Personal Information Protection Act (PIPA), online service providers must respond to a customer's request to disclose any record of their personal data being shared. The Supreme Court has sent the case back to the Seoul High Court for a retrial.
