In the North Texas area, it is not uncommon for a driver to receive a citation in one city only to find that the case is being prosecuted in the municipal court of a different city. This often happens due to Interlocal Agreements—contracts between neighboring municipalities (like Plano and Frisco) that allow one city to handle judicial functions for another.
However, a frequent question arises at trial: If your case is in a “foreign” court, does the State have to formally introduce that Interlocal Agreement into evidence to prove the court has the right to hear your case?
At Beltz Law Group, we stay at the forefront of these procedural nuances. Here is the breakdown of how Texas law treats these agreements in the courtroom.
The Evidentiary Gap: Rule 204

Criminal Defense Lawyer
The first thing to understand is that an Interlocal Agreement is not an ordinance. This distinction is critical for evidence purposes.
Under Texas Rule of Evidence 204, a judge can take “judicial notice” of municipal ordinances. This means the State doesn’t necessarily have to “prove” the ordinance exists with a paper copy; the judge is allowed to acknowledge it as law.
Interlocal agreements fall outside of Rule 204. Because they are contracts between government entities rather than laws or ordinances, a judge cannot simply take judicial notice of them. If the terms of the agreement are disputed, they must be treated like any other factual matter—requiring proof through general evidentiary rules.
Is the Agreement a Prerequisite for Trial?
Surprisingly, there is no published Texas court decision that explicitly states the State must formally introduce an interlocal agreement into evidence just to start a trial.
-
The Status Quo: Currently, it is an unsettled area of law. Many municipal courts operate under the assumption of jurisdiction based on these agreements without the prosecutor ever marking the contract as “Exhibit 1.”
-
The Risk for the State: Just because there isn’t a direct law requiring it doesn’t mean the State is safe. In cases like State v. Kurtz (2003), Texas courts have shown they will scrutinize the text of these agreements if they are challenged. If a defendant contests jurisdiction, the State is in a precarious position if they don’t have the document ready.
The Importance of the “Jurisdictional Challenge”

Criminal Defense North Texas
If you are a defendant in a municipal court and you believe the court lacks the authority to hear your case because it happened in another city, the burden of asserting that defense often falls on you.
-
If You Don’t Challenge It: If the existence or scope of the interlocal agreement is not disputed, the court will likely proceed without the document being admitted.
-
If You DO Challenge It: Once you contest jurisdiction on the grounds that no valid agreement exists (or that it doesn’t cover your specific offense), the State should be prepared to produce it. Without Rule 204 judicial notice to fall back on, the State has no legal basis to claim the agreement exists unless they show it to the court via formal admission or stipulation.
Legal Insight: The logic in Martin v. State (1987) suggests that when the State’s authority depends on a specific document, they should be prepared to prove it. Failure to do so could lead to a successful challenge on appeal.
Practical Implications for North Texas Drivers
If you were cited in City A but summoned to court in City B, the State is essentially relying on a “hidden” contract to prosecute you.
-
De Novo Appeals: The failure to introduce an interlocal agreement becomes even more significant if the case is appealed to a County Court at Law for a de novo trial. In that higher court, the State’s omission of the agreement could lead to a successful sufficiency-of-the-evidence challenge.
-
Forfeiture: If a defendant fails to timely object to the court’s jurisdiction, they may forfeit the right to complain about it later.
