Types of Law Enforcement Requests
Law enforcement uses different legal mechanisms to request data. Each has different requirements.
Subpoena
A subpoena compels you to produce documents or data. It can be issued by law enforcement, prosecutors, or courts.
Authority: Court or prosecutor, often without judicial review Standard: Much lower than search warrant Examples: "Produce all messages between User A and User B from January 1 to June 30" Your obligation: Generally must comply, but you can challenge if unreasonable
Subpoenas are common and often overly broad. You should evaluate whether they're reasonable before complying.
Search Warrant
A search warrant authorizes law enforcement to search for and seize evidence of a crime.
Authority: Court (judge must review and approve) Standard: Probable cause that a crime has been committed Examples: "Search the account of John Smith for evidence of child exploitation" Your obligation: Must comply immediately; challenging requires going to court
Search warrants are powerful and require judicial review, so they're used for serious crimes.
Administrative Subpoena
Less common, but law enforcement can sometimes issue subpoenas without court involvement using administrative authority.
Authority: Law enforcement agency itself (no judicial review) Standard: Varies; often requires "reasonable belief" of crime involvement Examples: Used by IRS, FBI's Financial Crimes Division, etc. Your obligation: Generally lower requirement to comply than court subpoenas
These are common in financial crimes and terrorism cases.
Wiretap / Interception Orders
Court orders authorizing law enforcement to monitor communications in real time.
Authority: Court (judge approves) Standard: Very high; requires showing less intrusive means aren't available Examples: "Monitor messages between User A and all contacts for 30 days" Your obligation: Must comply; provide access to real-time messages
These are rare because they're labor-intensive and high-standard to approve.
Emergency Requests
Law enforcement claims immediate danger (person in danger, imminent crime).
Authority: Law enforcement only, no court order Standard: Very fact-specific; varies by jurisdiction Examples: "Provide current location of User X, they have kidnapped a child" Your obligation: You can voluntarily provide limited emergency assistance, but you're not required to
Emergency requests are most commonly for child safety or imminent violence.
Legal Standards and Requirements
Different request types require different standards of proof and judicial review. Understanding this protects you from overly broad requests.
Fourth Amendment Protection (US)
The Fourth Amendment protects against "unreasonable searches and seizures." This applies to law enforcement access to user data.
Key cases:
- Riley v. California (2014): Cell phones require search warrant, not just subpoena
- Carpenter v. United States (2018): Historical location data (cell site records) requires search warrant, showing higher burden than subpoena
Implication for dating platforms: Law enforcement generally needs a search warrant (not just subpoena) for contents of messages. But they might only need a subpoena for account metadata (IP address, signup date, payment info).
Stored Communications Act (SCA)
The SCA governs law enforcement access to stored electronic communications.
18 USC 2704 requires:
- Search warrant: Full contents of communications (highest standard)
- Court order: Some communications data (medium standard, requires "specific and articulable facts")
- Subpoena: Subscriber information only (lowest standard, no judicial review)
Example: Law enforcement can subpoena your name, email, IP address. But they need a warrant to read your messages.
Differing Standards by Jurisdiction
- US: Fourth Amendment protects broadly; law enforcement needs warrants for content
- UK: Different legal standards; warrants still required but defined differently
- EU: Stronger privacy protections; warrants have higher standard
- Australia: Metadata laws allow broader access without warrants
Verification Procedures
Before responding to any law enforcement request, verify it's legitimate.
Red Flags
- Request is vague or overbroad ("all accounts from Seattle")
- Requestor claims to be law enforcement but won't provide credentials
- Request lacks case number, court docket, or other identifier
- Request lacks judicial authorization (when required)
- Request is from foreign law enforcement without proper channels
- Request contains language like "no need for a warrant" or "keep this confidential from user"
Verification Steps
Step 1: Confirm identity Ask the requestor for:
- Badge number or employee ID
- Agency contact information
- Direct phone number (call back to main agency switchboard, not number provided)
- Email from official agency domain
Verify this information independently. Don't call a number provided in the request; look up the agency and call them.
Step 2: Confirm authority Does the request include:
- Case or file number? (Should be present for any serious request)
- Court order or warrant? (Reproduce it; courts should be able to confirm)
- Grand jury subpoena indication? (Certain requests don't require court order)
Step 3: Confirm scope Is the request:
- Specific (not broadly fishing)?
- Relevant to a stated crime?
- Proportionate (asking for one year of data, not five years)?
Step 4: Document Keep records of:
- Who made the request
- Date received
- Exact scope and what was requested
- Whether it included court order/warrant
- Your verification steps
- Your response
What to Do If You Reject a Request
If you believe a request is overbroad, invalid, or lacks proper authority:
- Notify the requestor in writing that you need clarification or additional legal justification
- Provide a reasonable deadline (10 business days typical)
- If they provide additional justification, reassess
- If they don't, you can decline to respond
You're not required to comply with invalid requests. Declining won't result in contempt of court (you're not violating a court order if there is none).
When to Involve Lawyers
You should have an external lawyer review any request:
- From foreign law enforcement
- That's unusual or novel
- That you believe is overbroad
- Before declining a request
Cost: $1,000-$5,000 for law firm review, worth it to avoid missteps.
Scope and Limitations
Even if a request is valid, you can and should limit what you provide.
Scope Limitation
If law enforcement asks for "all messages from User A," but they only have a warrant for messages between User A and User B, provide only the requested messages.
If they ask for "all metadata on User A," but they have a warrant for "account information," provide only account information, not behavioral data.
Temporal Limitation
Requests should specify dates ("January 1 to March 31, 2025"). If they don't, provide only a reasonable timeframe (last 12 months typical).
If they ask for "all messages ever," you can push back and ask them to specify dates.
What Not to Provide
Even if requested, consider not providing:
Derivative data: If they ask for messages, don't provide a machine learning analysis of sentiment or behavioral patterns. Provide the raw data.
Other users' data: If they ask for messages between User A and User B, don't include messages from User A with other people.
Data you don't have: Don't infer or create data to comply with a request. If you don't track something, say so.
Sensitive data beyond scope: Even if law enforcement asks, decline to provide data outside the scope of the request.
Data Preservation and Retention
Once you receive a request or believe a crime is being investigated, you should preserve relevant data.
Preservation Obligations
If you receive a request, you should:
- Preserve all data the request covers
- Hold it for at least 6-12 months (check your local law)
- Don't delete or modify it
- Don't share it with the subject (if preservation is secret)
Failure to preserve can result in sanctions or contempt.
Preservation Periods
- Received request: Hold data for 6-12 months
- Legal hold: If law enforcement indicates ongoing investigation but hasn't formalized, preserve for 12+ months
- Criminal case: Hold through trial and appeals (2-5+ years)
Practical Implementation
You should have policies:
- When data preservation is triggered (request received, subpoena received, etc.)
- How to mark data as under preservation (database flag, separate storage)
- Who manages preservation (compliance officer, legal)
- How long to hold before deletion
- Audit trail of what was preserved
User Notification
This is complicated. Generally, you must notify users unless law enforcement requests secrecy.
Default: Notify Users
When you receive a law enforcement request, you should notify the user whose data you're about to produce.
Why notify?
- Users have Fourth Amendment rights (their data is their property)
- Users should know government is accessing their data
- Users can challenge the request in court
- Transparency builds trust
How to notify: Send notice within a reasonable time:
- "We received a law enforcement request for your data"
- "We will comply within X days unless you file an objection"
- Provide enough detail about the request so they can understand scope
Timeline: Typically 10 days advance notice, but varies. Some jurisdictions require immediate notice, others allow delayed notice.
Exception: Secrecy Orders
Law enforcement can request you keep the request confidential ("Notify the user and I'll get a court order to prevent them from fleeing").
Courts can issue "non-disclosure orders" preventing you from notifying users.
If you receive such an order:
- You must comply (it's a court order)
- Hold the request confidential as specified
- Keep records of the confidentiality order
- Notify the user after the order expires
Best Practice
- Notify users by default
- Comply with explicit non-disclosure orders only
- Keep records of what you disclosed and when
- Consider pushing back on overly long confidentiality periods
Building Your Process
You need a documented procedure before the first request arrives.

Written Policy
Document:
- How requests are received (email, mail, in-person)
- Who receives them (compliance officer, legal team)
- Verification procedures
- Scope limitations
- Data preservation requirements
- User notification procedures
- Documentation and archival
- Escalation (when to involve external counsel)
- Approval (who signs off on compliance)
Responsible Roles
Assign clear responsibility:
- Compliance officer: Receives and triages requests
- General counsel or external counsel: Reviews for legality and scope
- Data/engineering: Retrieves and formats data
- Finance/records: Archives request and response
Training
Ensure team understands:
- What types of requests exist
- Why verification matters
- When to push back
- How to preserve data
- When to escalate
- Confidentiality of requests (don't gossip about them)
Audit Trail
Every request should generate:
- Written log entry (date received, requestor, scope, deadline)
- Copy of request
- Verification documentation
- Decision and reasoning
- What was provided
- User notification (if sent)
- Counsel review (if obtained)
Keep for 7+ years.
Transparency Reports
Publish a transparency report showing law enforcement requests received.
Why Publish?
- Shows you take user rights seriously
- Demonstrates you're not a government partner
- Builds user trust
- Holds you accountable
What to Include
- Number of requests received (by country)
- Breakdown by type (subpoena, warrant, administrative)
- Number of users affected
- Number of requests you declined or challenged
- Percentage compliance rate
Example:
- Received: 47 requests (37 US, 8 EU, 2 UK)
- Complied: 39 (83%)
- Declined: 5 (overly broad)
- Pending judicial review: 3
- Users affected: 52
Caveats
You don't need to publish classified or sensitive information. If a request involves national security, you can:
- Publish aggregate numbers ("requests from US intelligence agencies: 5")
- Decline to publish if doing so reveals investigation details
Reporting Frequency
Publish annually. Multiple platforms publish semi-annually or quarterly.
Example: Google's Transparency Report, Microsoft's Legal Requests Report, Apple's Global Government Data Requests Info.
International Requests
Foreign law enforcement making requests is more complicated.
Types of International Requests
Mutual Legal Assistance Treaty (MLAT): Official channel between US and another country's government. Formal, slow (6-12 months).
Rogatory letter: Court in one country requesting court in another to issue order.
Direct request: Foreign law enforcement contacting you directly.
Standards
International requests generally require:
- Higher showing of need (similar to warrant standard)
- Compliance with both US and foreign law
- Verification that requestor is legitimate
When to Decline
Decline international requests if:
- Requestor hasn't used MLAT or official channels
- Request conflicts with US law (e.g., asking you to violate GDPR)
- Request is from a government without rule of law protections
- Verification is impossible
Best Practice
- Require MLAT or official channels for international requests
- Involve external counsel (costs justified by complexity)
- Verify through US State Department or similar official channels
- Document everything
Key Takeaways
- Law enforcement will request user data. Have a process before the first request.
- Verify every request is legitimate (identity, legal authority, scope).
- Different request types have different legal standards. Don't treat a subpoena the same as a warrant.
- You can and should push back on overbroad requests.
- Preserve data when requests come in; don't delete.
- Notify users by default (unless court orders otherwise).
- Keep detailed records of every request and your response.
- Involve external counsel for complex or novel requests.
- Publish a transparency report showing how many requests you receive and how you handle them.
- Your goal is to comply with valid legal processes while protecting user rights and privacy.
A good process protects users, protects you, and actually helps legitimate law enforcement investigations.
