United States v. Leon

Section summaryLeon held that the exclusionary rule does not apply when officers act in objectively reasonable reliance on a warrant later found defective. The deterrence rationale of exclusion does not apply when officers acted in good faith.

The Leon framework:

  • Officer reliance on warrant must be objectively reasonable.
  • Reliance is unreasonable where the affidavit is bare bones or knowingly false.
  • Reliance is unreasonable where the warrant is facially defective.
  • Otherwise, evidence is admissible despite warrant defect.

Davis v. United States

Section summaryDavis extended good faith to reliance on appellate precedent later overturned. Police who relied on then-binding precedent are protected from exclusion when the precedent is later changed.

The Davis framework:

  • Reliance on then-binding precedent is objectively reasonable.
  • Subsequent overruling does not trigger exclusion.
  • Limited to specifically-controlling precedent.
  • Does not apply to novel constitutional issues.

Texas Article 38.23(b)

Section summaryTexas Article 38.23(b) provides a narrower good-faith exception. The exception applies only to officers acting in objective good faith on a warrant issued by a neutral magistrate based on probable cause.

The Texas provision:

  • Limited to warrant-based searches.
  • Requires objective good faith.
  • Magistrate must be neutral.
  • Affidavit must establish probable cause.
  • Does not extend to other categories of error.

McClellan v. State

Section summaryMcClellan v. State, PD-0654-22, refined Texas application of the good-faith exception. The Court of Criminal Appeals addressed the specific scope and limits of the Texas provision.

McClellan considerations:

  • Reaffirmed the narrower Texas scope.
  • Addressed specific factual patterns.
  • Refined the analysis for officers relying on warrants.
  • Counsel should review the specific facts of any case against McClellan and current Texas application.

Federal vs Texas

Section summaryFederal good-faith exception is significantly broader than Texas. Where federal good faith applies, federal evidence is admissible; Texas Article 38.23 still excludes under independent state grounds.

Practical Application

Section summaryIn Texas state cases, Article 38.23 controls. In Texas federal cases, federal exclusionary rules apply. Many state cases are governed by Texas's broader exclusion.

Practical considerations:

  • State cases: Texas Article 38.23 controls; narrower good-faith exception.
  • Federal cases in Texas: federal rules apply; broader good-faith.
  • Choice of forum can matter for suppression outcomes.
  • Counsel should plead both federal and Texas grounds.

Hearing Strategy

The suppression hearing is the moment where good faith under article 38.23 vs. leon cases are won or lost. The judge hears live testimony, reviews documents, examines video, and makes credibility determinations that the appellate court will not lightly disturb. Counsel preparing for a warrant the State will defend with the good-faith exception should treat the hearing as if it were the trial — because in many cases it is.

Preparation centers on the officer. The officer's body-camera and dash-camera video, the offense report, the search-warrant affidavit if one exists, dispatch logs, and any pre-existing investigative documentation create the testable record. Inconsistencies between the officer's later report and the contemporaneous video are the single most productive cross-examination ground. The officer's training history, prior testimony in similar cases, and prior disciplinary record may be available through public-information requests and informal discovery.

The defense should also prepare its own witnesses where the facts permit. Civilians who observed the encounter, technical experts on any disputed technology (cell-site data, forensic imaging, video analysis), and the defendant if a strategic decision is made to testify can each shift the record. Texas defendants who testify at a suppression hearing do not waive Fifth Amendment protections for the trial itself under the standard rule, but the strategic implications must be considered carefully with counsel.

Article 38.23 Considerations

Texas Code of Criminal Procedure Article 38.23(a) provides a state-law exclusionary rule broader than the federal Fourth Amendment remedy. The Texas rule requires suppression of evidence obtained in violation of any law — not just the Constitution. The Texas rule also does not include a general good-faith exception; Article 38.23(b) creates only a narrow good-faith exception for warrants, not for warrantless conduct.

For cases involving a warrant the State will defend with the good-faith exception in Texas state court, the Article 38.23 analysis often produces a stronger suppression motion than the parallel federal analysis. Counsel should brief both standards and identify the specific statutory or constitutional provision the State conduct violated. Where the violation is purely statutory (a peace officer exceeded statutory arrest authority, an inventory search violated the agency's written policy, a search was conducted by a person without authority under the Code of Criminal Procedure), Article 38.23 may exclude what the federal rule would admit.

The most successful Article 38.23 motions identify the specific statute or rule violated, quote the violated provision, link the violation to the evidence the State will use at trial, and develop the factual record at hearing to support the suppression finding. Generic Fourth Amendment briefing often misses the Article 38.23 leverage that Texas practice provides.

The Leon Good-Faith Exception

United States v. Leon, 468 U.S. 897 (1984), established the good-faith exception to the Fourth Amendment exclusionary rule. Evidence obtained pursuant to a warrant later determined to be unsupported by probable cause is admissible if the officers acted in objectively reasonable reliance on the warrant. The exception's premise is that the exclusionary rule is designed to deter police misconduct, not to punish honest mistakes by magistrates.

Leon identifies four situations where the good-faith exception does not apply: (1) the affidavit contained materially false statements or recklessly inaccurate information (overlapping with Franks v. Delaware); (2) the magistrate wholly abandoned the neutral and detached role; (3) the affidavit was so lacking in indicia of probable cause that no reasonable officer could believe it established probable cause; or (4) the warrant was so facially deficient (in particularity or scope) that no reasonable officer could believe it valid.

Federal courts have applied Leon broadly. The defense's best path through Leon challenges typically focuses on the third and fourth categories — bare-bones affidavits or facially defective warrants — rather than disputing magistrate neutrality, which is rarely successful.

Texas Article 38.23 — No Across-the-Board Good Faith

The Texas exclusionary rule at Code of Criminal Procedure Article 38.23 differs from the federal rule in a critical respect. Article 38.23(b) provides a good-faith exception only for officers who acted in objective good faith reliance upon a warrant issued by a neutral magistrate based on probable cause. Texas does not recognize a general good-faith exception for warrantless conduct or for non-warrant procedural violations.

The practical implication is that evidence obtained in violation of Texas statutory law — even if obtained in good faith — remains subject to suppression under Article 38.23(a). Federal good-faith doctrine does not save the evidence in Texas state court. Counsel should brief both Article 38.23(a) (which excludes evidence obtained in violation of any law) and Article 38.23(b) (which carves out a narrow good-faith exception for warrants only).

Common Texas statutory violations not covered by good-faith include: unauthorized peace-officer activity outside jurisdiction; statutory violations of inventory-search procedures; failure to comply with statutory chain-of-custody requirements; and procedural violations in administrative-search programs. Each provides a state-law exclusionary remedy that the federal good-faith doctrine cannot defeat.

Briefing Around the Good-Faith Exception

Defense briefing on suppression motions should anticipate the State's invocation of good-faith and address each prong directly. For federal cases, the defense should argue that one of the four Leon categories applies. For Texas cases, the defense should identify whether the violation is a warrant violation (potentially good-faith-protected under 38.23(b)) or a non-warrant statutory violation (not protected).

The "bare bones" attack on the affidavit is most effective when the affidavit relies on conclusory recitations rather than specific facts. An affidavit stating that the affiant "knows from training and experience that drug dealers store evidence in their homes" without specific facts tying this defendant to that pattern provides a strong target for the "no reasonable officer could believe it established probable cause" standard.

Facial-deficiency arguments under Leon's fourth prong work best when the warrant fails the particularity requirement of the Fourth Amendment. General warrants authorizing searches of "all premises" or "all records relating to" a specific person, without limits, are vulnerable. Counsel should compare the warrant against the particularity standard set out in Stanford v. Texas, 379 U.S. 476 (1965), and progeny.

The Narrow Article 38.23(b) Good-Faith Exception

Article 38.23(b) of the Texas Code of Criminal Procedure creates a narrow good-faith exception that applies only to warrant-based searches. The exception covers a peace officer who acts in objective good faith reliance upon a warrant issued by a neutral magistrate based on probable cause. The exception is substantially narrower than the federal Leon good-faith doctrine.

The Article 38.23(b) exception requires three elements: (1) a peace officer must have executed the warrant; (2) the officer must have acted in objective good faith reliance; and (3) the warrant must have been issued by a neutral magistrate based on probable cause. All three elements must be satisfied; the absence of any one defeats the exception.

The "objective good faith" prong has been interpreted to require that no reasonable officer in the executing officer's position would have known the warrant was invalid. This is similar to the federal Leon objective-reasonableness standard but with the additional Texas requirement that the magistrate's probable-cause determination be supportable on the affidavit's face.

The exception does not extend to: warrantless searches (no warrant means no good-faith exception); searches under warrants supported by Franks-deficient affidavits (which fail the "based on probable cause" element); searches under warrants so facially deficient that no reasonable officer could have believed them valid; or searches that exceeded the warrant's scope. Defense counsel should examine each potential defect and brief why the narrow Article 38.23(b) exception does not apply.

The McClellan v. State framework and the Texas-specific analysis

The McClellan v. State, 701 S.W.2d 671 (Tex. App.—Dallas 1985), framework continues to inform the Texas good faith exception analysis under Article 38.23. The Texas exclusionary rule provides broader protection than the federal framework in some respects but includes its own limitations. The defense should develop the specific Texas-law analysis rather than relying solely on federal Fourth Amendment doctrine. The cumulative Texas framework can produce different results than the federal analysis in specific cases.

Frequently Asked Questions

Does the federal good faith exception apply in Texas state court?
Texas state courts apply Texas Article 38.23, which has a narrower good-faith exception than federal Leon/Davis. The federal exception applies to federal prosecutions; state cases follow Texas law.
Can the State invoke good faith on a search without a warrant?
Generally no. Texas Article 38.23(b) good-faith applies to warrant-based searches. Warrantless searches typically do not qualify for the Texas good-faith exception.
What if the officer relied on later-overturned Texas case law?
Texas does not generally adopt the federal Davis rule. Texas Article 38.23 typically requires exclusion even where officers acted on then-binding precedent, with limited specific exceptions.
Are there other good-faith categories in Texas?
Limited. Texas Article 38.23(b) is the principal good-faith provision and is narrower than federal law. Other categories of state-law-based exceptions are rare and case-specific.
