1. What Makes a Search or Seizure Unlawful?
The Fourth Amendment to the United States Constitution and Article I, Section 12 of the New York Constitution protect individuals and corporate entities against unreasonable searches and seizures. Law enforcement officials must obtain a valid warrant issued upon probable cause, supported by oath or affirmation, and describing the specific locations to search and items to seize. When officers execute a search without meeting these legal standards, the search may be declared unlawful upon judicial review.
Exceptions to the Warrant Requirement
Police officers generally need a warrant before searching business premises or seizing company property. However, specific exceptions to the warrant requirement exist under established case law:
- Voluntary consent provided by an individual with authority over the property.
- Exigent circumstances, such as risks to safety or the imminent destruction of evidence.
- Plain view, where officers lawfully present observe evidence of illegal activity.
- Searches conducted incident to a lawful arrest.
When Officers Exceed the Scope of a Warrant
The lawful scope of a search depends on the specific language of the warrant, the particularity of the described items, and the execution methods used by officers. A warrant authorizing the inspection of paper records does not automatically grant unrestricted access to corporate servers, mobile devices, or cloud accounts. Determining whether law enforcement exceeded its authorized mandate requires a careful examination of the warrant and the physical or digital evidence taken during the search.
2. What to Do Immediately after Property or Evidence Is Seized
The immediate response following a search warrant execution sets the foundation for subsequent court challenges. Company management must keep complete copies of the warrant, inventory sheets, and property receipts provided by law enforcement. Employees must not alter or delete physical or electronic records, as such conduct can result in independent criminal charges.
Document What Officers Searched and Seized
Designating staff to record which offices officers entered, which devices were seized, and which accounts were accessed creates an accurate record for later court proceedings.
| Asset Category | Target Items | Strategic Legal Considerations |
|---|---|---|
| Digital Hardware | Servers, laptops, mobile phones | Record serial numbers and request complete inventory receipts. |
| Financial Records | General ledgers, banking files | Seek access or copies to maintain essential corporate operations. |
| Cloud Accounts | Email accounts, remote storage | Determine if extractions exceeded the warrant's scope. |

Protect Attorney-Client Privileged Materials
When seized materials contain attorney-client privileged communications, law enforcement does not automatically create privilege logs. Defense counsel may need to promptly seek appropriate privilege-review procedures or judicial intervention to prevent protected communications from being disclosed to the prosecution team.
3. Can Illegally Seized Evidence Be Suppressed?

In state criminal prosecutions, defendants challenge illegally obtained evidence by filing a motion to suppress under Criminal Procedure Law (CPL) Article 710. CPL § 710.20 permits a defendant to move for the suppression of physical property or digital data gathered through unlawful searches.
Grounds for a Motion to Suppress
A motion to suppress may challenge the warrant on several grounds:
- Lack of probable cause within the supporting affidavit.
- False statements made intentionally or recklessly by the affiant officer.
- Unconstitutional vagueness or overbreadth in the warrant's terms.
- Unlawful execution or warrantless searches conducted without a recognized exception.
When Derivative Evidence May Be Excluded
Suppression claims often involve the fruit of the poisonous tree doctrine, which may extend the exclusionary rule to evidence derived from an initial constitutional violation. Suppression is not automatic, however, because courts consider exceptions such as attenuation, independent source, and inevitable discovery.
Filing Deadlines and Suppression Hearings
Under CPL § 710.40, a motion to suppress must generally be filed within the forty-five-day time frame set by CPL § 255.20(1). Late filings may be permitted if the defense discovers new material facts that could not have been raised earlier with reasonable diligence. Courts may resolve factual disputes concerning suppression through a pretrial evidentiary hearing.
4. How to Seek the Return of Seized Property
Suppression of evidence prevents prosecutors from using items at trial, but it does not automatically force law enforcement to return seized property. Obtaining the physical return of corporate equipment, records, or funds requires separate statutory mechanisms depending on whether the matter proceeds in state or federal court.
Return of Property in New York State Cases
In state matters, property management and disposal are governed by CPL §§ 690.50 and 690.55. If a court grants a motion to suppress, CPL § 710.70(1) authorizes the court to order the return of the property to the defendant, provided the items are not otherwise subject to lawful detention or forfeiture.
Return of Property in Federal Cases
In federal matters, an aggrieved party may move for the return of property under Rule 41(g) of the Federal Rules of Criminal Procedure. A Rule 41(g) motion is typically filed in the district where the property was seized.
When Asset Forfeiture Applies
When government authorities hold property under civil or criminal asset forfeiture statutes, a separate legal process applies. Property owners may need to file a formal claim asserting an interest in the property and challenging the government's basis for forfeiture.
5. Frequently Asked Questions
What should employees do if law enforcement agents arrive with a search warrant?
Employees should request copies of the warrant and the lead agent's credentials while notifying corporate management and legal counsel. Staff must not physically interfere with officers, but they are not required to answer substantive investigative questions or consent to searches beyond the terms of the warrant.
