Legal experts say the findings could open the door for appeals and raise serious questions about past convictions. Read More

🏛 Caselaw Brief:
Fruit of the Poisonous Tree vs. Inevitable Discovery

What’s the difference, and why does it matter in your case?

Wong Sun v. United States (1963)

Evidence obtained directly or indirectly from an illegal search, seizure, or arrest is considered "fruit of the poisonous tree" and is generally inadmissible in court.

This includes:

• Physical evidence

• Witness statements

• Anything discovered because of the constitutional violation

Unless the prosecution can show:

• An independent lawful source

• Inevitable discovery

• A break in the causal chain (attenuation)

Nix v. Williams (1984)

This case created the inevitable discovery doctrine.

Even if evidence was found unlawfully, it may still be admitted if law enforcement can prove they would’ve found it anyway through a separate, legal process already underway.

In Nix, officers found a murder victim’s body after an improper interrogation—but the search team was already in the area. The Court ruled the discovery was inevitable.

Other applicable caselaw: United States v. Andrade a 1986 case out of the 9th Circuit.

Quick Recap

✅ Admissible under Nix v. Williams

• A warrant was already in motion

• A K9 or search team was already on scene

• The evidence would have been found through lawful steps regardless

❌ Suppressed under Wong Sun

• The evidence was found only because of illegal police action

• No independent or lawful method was in progress

• No valid exception applies

Scenario answer:

Yes. Courts have held that evidence was admissible because a lawful search warrant was already in progress and the drugs would have been found regardless. Since the process to obtain the warrant was well underway and based on independent probable cause, the doctrine of inevitable discovery applied.

Search Warrant Basics: A Quick & Dirty Guide

📄 What You Need to Get a Warrant

• Probable Cause: Facts that lead a reasonable person to believe evidence of a crime is at the location.

• Particularity: Be specific—what are you searching for and where?

• Fresh Info: Old info = weak warrant. Keep it recent and relevant.

• Affidavit: Clear, fact-based writing. No fluff or copy-paste junk.

• Approval: Judge or MDJ signs off before you hit the door.

Tactical Considerations

For Homes :

• Who lives there? Any firearms or violent history?

• Kids, elderly, or other vulnerable people inside?

• Cameras, fences, dogs?

• Knock vs. No-Knock 🚪: Needs solid justification—safety or risk of evidence being destroyed.

For Vehicles :

• Is it mobile or parked?

• Will you stop it in motion or grab it later?

• Secure it ASAP—cars can move fast, and so can your PC.

Types of Warrants

• Property Warrants: Homes, cars, lockers, garages—physical locations.

• Tech & Digital Warrants:

  • Phones: Texts, pics, call logs, apps.

  • Cloud: iCloud, Google Drive, email accounts.

  • Social Media: Meta, Snapchat, IG (slow process—plan ahead).

• Tracking Warrants: GPS trackers, cell pings.

• Body Warrants: DNA swabs, blood draws, evidence on/in a person.

The cleaner the warrant, the stronger your case—and the less likely your hard work gets thrown out.
