How it applies
Common Examples
2
State Prescription Database
Progressive Healthcare pharmacies report names, addresses, and dosages for patients prescribed high-risk medications into a secure state database with access limited to regulators. Patient Philip Powell objects that the collection invades his privacy. The state maintains the system under reasonable safeguards for health oversight, so the administrative recordkeeping proceeds without constitutional violation.
Petition Circulator Identification
A state law requires initiative petition circulators to wear badges disclosing their names and addresses. Pablo Perez, a circulator for a ballot measure, refuses and challenges the rule. Because the requirement burdens core political speech and is not narrowly tailored to a compelling interest, the disclosure mandate is struck down.

Frequently Asked
3
What constitutes personal data under privacy regulations?+
Personal data includes any information relating to an identified or identifiable natural person, such as names, identification numbers, location data, or online identifiers. The definition focuses on whether the person can be identified directly or indirectly from the data.
Supporting sources
Does constitutional privacy bar government collection of personal data?+
No. Administrative collection of personal information such as patient prescription records is permissible when reasonable safeguards protect against improper disclosure. The collection serves legitimate regulatory purposes without invading a protected zone of privacy.
Supporting sources
When are laws requiring disclosure of personal information in political contexts invalid?+
Laws requiring disclosure of personal information in core political speech, such as petition circulation, are subject to strict scrutiny. They are struck down when not narrowly tailored to a compelling interest because restrictions on anonymity in political advocacy are presumptively suspect.
