I am Joel Brand, and I defend DUI cases across California. One of the most unsettling calls I get is from someone who just received an arraignment date and is sitting there wondering: I have not seen a single police report, I have no lab results, and I do not even know what evidence the prosecution actually has against me. How am I supposed to decide what to do? This post explains what is happening, why it is completely normal, and what concrete steps protect your rights when the evidence has not arrived yet.
Why You Almost Never Have Discovery Before Your Arraignment
The arraignment is the first formal court appearance, and its only required purpose is to read you the charges and take your plea. It is not a trial, and it is not an evidence review session. The prosecution files a complaint, the court schedules you to appear, and both happen quickly, often within days of your arrest. Police reports, breath machine calibration records, blood lab results, and body camera footage all take far longer to compile, test, and organize. So it is perfectly routine to walk into an arraignment with essentially no paperwork in your hand. What matters is that you understand this gap and do not make a permanent decision based on incomplete information.
What Discovery Actually Includes in a California DUI Case
Discovery is the set of materials the prosecution must share with your defense. In a DUI case that typically means the arresting officer's report, the DS 367 administrative document, the breath test printout or blood test results, calibration and maintenance logs for the testing device, dispatch records, any body camera or dashcam footage, and witness statements. The blood results alone can take four to eight weeks from the date of the draw. Until those records arrive and are reviewed, no one, not you, not a public defender, and not a private attorney, can give you a fully informed opinion on the strength of the case against you. If you want to understand why the blood results take so long, I cover that in detail on the blog.
The Plea You Enter at Arraignment Does Not Have to Be Final
At your arraignment you will almost certainly enter a not guilty plea. That is the standard, correct move at this stage. It does not mean you are claiming innocence forever. It simply preserves your right to review the evidence, negotiate, or take the case to trial. A not guilty plea keeps every option open. What happens at a DUI arraignment is something I explain in depth in the library, but the short version is: do not agree to anything substantive, do not waive important rights, and do not plead guilty just to get the hearing over with.
What the Prosecution Can and Cannot Do Without Complete Evidence
The prosecution can charge you and demand a plea before lab results are back. That is legal in California. What they cannot ethically do is withhold evidence once it exists and a defense request has been made. Under California Penal Code 1054.1 the prosecution must disclose relevant materials in their possession before trial. Once your attorney sends a formal discovery demand, a clock starts. The prosecution also has ongoing Brady obligations, meaning they must turn over any evidence that is favorable to you even if you did not specifically ask for it. Knowing these rules exist is one reason you want an attorney making demands on your behalf as early as possible.
How Missing Evidence Can Actually Help Your Defense
This may surprise you, but evidence that has not yet arrived is not neutral. It is an opportunity. If the blood sample was mishandled between the draw and the lab, the chain of custody may be broken. If the breath machine has not been properly maintained, a calibration defense may be available. If the officer's report is filled in after the fact and contradicts the dashcam, that inconsistency matters. None of that becomes visible until the records are actually in hand. Filing a timely motion to suppress evidence depends on knowing what evidence exists and how it was obtained. Rushing to plead guilty before any of that is reviewed means you may be waiving defenses you never knew you had.
What Happens at the Pretrial Conferences While You Wait
After the arraignment, the case typically moves into a series of pretrial conferences. These are scheduling and negotiation hearings. Your attorney appears, requests discovery, reviews what comes in, and evaluates whether to file motions, negotiate a reduction, or set the case for trial. Continuances are frequently used at this stage to give both sides enough time to receive and review everything. This is not delay for its own sake. It is the part of the process designed specifically to close the gap between your arrest and a fully informed decision. A case that seems strong for the prosecution at arraignment sometimes looks very different once calibration logs, body camera footage, and a proper review of the DS 367 are complete.
Why Waiving Time Strategically Can Work in Your Favor
California gives you the right to a speedy trial under Penal Code 1382. You also have the right to waive that right strategically. In a DUI case where critical lab results or footage have not arrived, waiving time so the defense can fully review discovery is often the smarter move. An attorney who rushes you to trial before the blood results come back cannot challenge those results effectively. Patience in the pretrial phase is not weakness. It is preparation.
The DMV Side of This Equation
While the criminal case is waiting for discovery, your DMV administrative hearing has its own tight deadline. You had ten days from your arrest to request a hearing or your license suspension became automatic. The DMV hearing and the criminal court case are separate proceedings and they run on separate tracks. But the discovery your attorney obtains from the criminal side, including the police report and the DS 367, often overlaps with what matters at the DMV. The DMV discovery packet is its own document set, and knowing what is in it early can shape your hearing strategy. If you have not yet made sense of your pink slip and what it triggers, the DS 367 overview is a good place to start.
Should You Try to Negotiate Before Discovery Arrives
Sometimes a prosecutor will float an early offer at the arraignment, often before anyone has read the file carefully. These early offers are sometimes reasonable and sometimes not. Without seeing the evidence, you have no way to evaluate whether the offer is better or worse than what you would likely get after a full review. The factors that influence whether a wet reckless offer is extended depend heavily on the specifics of the evidence, your record, and the jurisdiction. Accepting a plea before discovery arrives is almost always premature. In most cases the right answer is to enter not guilty, request discovery formally, and revisit negotiations once you actually know what the prosecution has.
What You Should Do Right Now
If you have an arraignment date and no evidence in hand, the most important thing you can do is get an attorney before that date, not after. An attorney who appears at arraignment with you can enter the not guilty plea, formally demand discovery on the record, begin requesting footage and records before they disappear, and make sure you do not accidentally waive anything important. The role of a DUI attorney is most valuable in the early stages when decisions about pleas and waivers are being made under time pressure and with incomplete information. Waiting until after the arraignment to find counsel means some of those early strategic choices are already made for you, and not necessarily in your favor.
This Is General Information, Not a Guarantee
Every DUI case in California turns on its own facts, the county, the officer, the testing method, and a dozen other variables. Nothing in this post is legal advice for your specific situation, and nothing here guarantees any particular outcome. What I can tell you is that understanding this phase of the process keeps you from making a rushed, uninformed decision that you cannot undo.
