If you’re charged with manufacture or delivery of a controlled substance in Collin County — “MAN/DEL” around the courthouse — there’s a good chance the State’s case runs through a confidential informant who made the buy.
When it does, one motion I like to file early is a motion under Texas Rule of Evidence 508 to make the State say who that informant is. If the court finds the informant’s testimony is necessary and the State still won’t name them, the rule says the court must dismiss the charge on the defendant’s motion.
How These Cases Usually Get Built
A lot of MAN/DEL cases start with a controlled buy. An officer meets with an informant, searches them, hands them recorded buy money, and sends them to make a purchase. The informant comes back with the drugs and gets debriefed. Sometimes there’s a recording. Often it’s partial, from a distance, or audio only.
Informants usually aren’t volunteers. Many are working off their own pending charges, getting paid per buy, or both. In the State’s file, they’re a number, not a name.
That’s what makes this motion work. In a controlled buy, the informant is often the only civilian who was actually there. The officer saw the informant walk in and walk out. The informant is the one who saw what happened — which is why the informant’s identity comes up again and again in drug charge defense in Collin County.
The Text of Rule 508
The government has a privilege to keep its informants secret. Rule 508(a) lets the State refuse to disclose the identity of a person who furnished information to law enforcement in an investigation. However, the same rule has an exception written for exactly this kind of case.
Rule 508(c)(2)(A) states:
“In a criminal case, this privilege does not apply if the court finds a reasonable probability exists that the informer can give testimony necessary to a fair determination of guilt or innocence. If the court so finds and the public entity elects not to disclose the informer’s identity: (i) on the defendant’s motion, the court must dismiss the charges to which the testimony would relate; or (ii) on its own motion, the court may dismiss the charges to which the testimony would relate.”
The two words I care about are must dismiss. Once the court makes that finding, and the State still won’t give up the name, dismissal on the defendant’s motion isn’t up to the judge’s discretion.
The State gets protection along the way. After the defense makes its showing, the court lets the State respond privately, in camera, with no counsel or party present. Nothing is revealed unless the court finds the exception applies.
Why This Motion Fits So Many Collin County Cases
Collin County frequently indicts delivery cases built around controlled buys where the informant is the only civilian witness.
Under Rule 508, the defense needs a plausible showing that the informant could provide testimony necessary to a fair determination of guilt or innocence. Speculation alone isn’t enough. Bodin v. State, 807 S.W.2d 313 (Tex. Crim. App. 1991).
An informant who personally made the buy is an eyewitness, which provides a strong basis for disclosure. In Anderson v. State, 817 S.W.2d 69, 72 (Tex. Crim. App. 1991), the court held that disclosure was required even though an undercover officer witnessed the transaction, because the informant could corroborate or contradict the officer’s account. See also Heard v. State, 995 S.W.2d 317, 321 (Tex. App.—Corpus Christi 1999, pet. ref’d); Coleman v. State, 577 S.W.3d 623, 636 (Tex. App.—Fort Worth 2019, no pet.).
The informant’s testimony doesn’t have to favor the defense. In State v. Lerma (Tex. Crim. App. 2021), the court upheld a Rule 508 dismissal in a capital murder case because testimony supporting guilt can also be necessary to a fair determination.
The showing is the easy part. What happens next is up to the State.
What the State Must Decide
Once the court makes the finding, the State has to decide which it values more: this case, or this informant.
Informants are valuable because police can use them again. One informant may be working several cases at once, and naming them in open court ends that — and can put them at risk. Prosecutors know it. Rule 508 puts the cost of secrecy on the State’s case instead of on the accused’s ability to confront the person who says he sold drugs.
That’s why I file it early. It forces the decision when the State has the least invested in the prosecution and the most invested in keeping its informant working.
The motion has constitutional weight behind it, too. Keeping an eyewitness hidden from the defense implicates the right to confront witnesses, the right to present a defense, and due process and due course of law under the United States and Texas Constitutions. And if a trial court wrongly refuses disclosure, the harm analysis on appeal looks at the effect of the error — not at how strong the rest of the State’s evidence seemed. Anderson, 817 S.W.2d at 73.
When Does Rule 508 Not Require Disclosure?
Rule 508 generally does not require disclosure when the informant only gives police a tip. For example, if an informant told officers that drugs were in a house, and officers then got a warrant and found the drugs themselves, the informant usually isn’t a witness to the charged offense. The case rests on what police found, not on what the informant saw.
Rule 508 handles that situation under a much narrower provision. Where an informant’s information is used to show a search was legal, the court may order disclosure only if it isn’t satisfied that the information came from an informant reasonably believed to be reliable or credible. (Tex. R. Evid. 508(c)(3)). That goes to the warrant, not to guilt, and it’s a much harder showing.
So the first question in any case like this: was the informant a participant — the buyer — or just a source?
How Does a Rule 508 Motion Work With a Discovery Request?
An ordinary discovery request won’t necessarily reveal a confidential informant’s identity. Article 39.14, the Michael Morton Act, gives the defense broad access to the State’s file, including offense reports, witness statements, and other material evidence. Watkins v. State, 619 S.W.3d 265, 291 (Tex. Crim. App. 2021).
Once a request is made, the State must search for and produce those materials as soon as practicable. State v. Heath, 642 S.W.3d 591, 597 (Tex. App.—Waco 2022), aff’d, 696 S.W.3d 677 (Tex. Crim. App. 2024). However, Article 39.14 applies to materials “not otherwise privileged.” An informant’s identity is protected under Rule 508 unless an exception applies.
The two procedures work together. Discovery can provide an offense report establishing that an informant participated in a controlled buy. That information can support the showing needed for a Rule 508 motion seeking disclosure of the informant’s identity.
What Other Motions Can Help in a MAN/DEL Case?
A Rule 508 motion is only one part of defending a manufacture or delivery charge. Depending on the investigation and evidence involved, the following may also be applicable to your case:
- Motion to suppress the search warrant: The affidavit has to establish probable cause on its own terms. If it contains statements the affiant knew were false or made with reckless disregard for the truth, the defense can challenge them under Franks v. Delaware, 438 U.S. 154 (1978). Informant-based affidavits are often thin on reliability or stale on timing. Evidence obtained in violation of the law is excluded under Tex. Code Crim. Proc. art. 38.23.
- Motion to suppress the traffic stop: The stop needs reasonable suspicion, and officers can’t prolong it past its purpose — to wait for a dog, for example — without independent reasonable suspicion. Rodriguez v. United States, 575 U.S. 348 (2015). Whether any consent to search was voluntary is a separate question.
- Motion to quash the indictment: Delivery can be by actual transfer, constructive transfer, or offer to sell. Tex. Health & Safety Code § 481.002(8). On a timely motion to quash, the State has to say which one it’s relying on. Ferguson v. State, 622 S.W.2d 846, 850–51 (Tex. Crim. App. 1980). Indictment defects have to be raised before trial, or they’re waived. Tex. Code Crim. Proc. art. 1.14(b).
- Motion to suppress statements: Anything said in custody has to meet the requirements of Article 38.22 and Miranda.
- Lab and weight: The penalty range turns on the weight and penalty group. Objecting to the lab’s certificate of analysis under Article 38.41 requires the State to bring the analyst to testify, consistent with Melendez-Diaz v. Massachusetts, 557 U.S. 305 (2009).
- Entrapment: If the informant pushed the sale, entrapment under Tex. Penal Code § 8.06 may be available, and Texas allows it to be raised at a pretrial hearing. Tex. Code Crim. Proc. art. 28.01, § 1(9).
Not every motion applies to every drug case. The investigation, charging documents, and available evidence help determine which challenges are worth pursuing.
What Should You Do if Your Drug Case Involves a Confidential Informant?
If your drug charge involves a controlled buy or confidential informant, what you do after the arrest can affect your case. There are a few important precautions to take:
- Don’t try to identify or contact the informant. Contacting someone you suspect could lead to additional allegations, including witness tampering.
- Don’t discuss the case on jail phones or with people who may have been involved in the alleged transaction.
- Ask your lawyer whether the informant participated in the offense. The distinction between a participant and someone who merely provided information can affect whether disclosure is available under Rule 508.
An attorney can examine the circumstances of the alleged transaction and determine whether a Rule 508 motion or another legal challenge is appropriate.
