DUI
The license fight and the criminal case run on separate tracks, and the license side moves first. I handle both.
DuPage County, IllinoisFormer ProsecutorCriminal Defense
For eight years I prosecuted DUI and felony cases for the DuPage County State's Attorney, and I supervised the felony trial division. Then I spent five more as Downers Grove's village prosecutor. Now I defend people charged with DUI, felonies and misdemeanors, and I know how the case against you gets built because I spent 13 years building them.

What I Learned on the Other Side
A prosecutor's file is only as strong as the stop, the search, the testing and the paperwork behind it. I spent a decade reading those files from the inside. Now I read yours.
I made charging and plea decisions for years, so I know which facts move a case toward reduction, diversion or dismissal and which ones a prosecutor won't bend on. We use that early to decide where to push.
I taught at the Suburban Law Enforcement Academy. I know what officers are taught to write in a report, how a stop or search is supposed to be handled, and what it looks like when it is not.
I tried felonies up to first-degree murder and supervised other trial prosecutors. Every case I take is prepared as if it is going in front of a jury, because that preparation is what gives a negotiation its weight.
Case Types
I defend people charged with crimes in DuPage County and the surrounding counties, from a first misdemeanor to the most serious felonies.
The license fight and the criminal case run on separate tracks, and the license side moves first. I handle both.
A felony puts your freedom, your record and your career at stake. I spent six years prosecuting them and now defend them from the first hearing to trial.
A misdemeanor can still mean jail, a permanent record and a lost job, so I prepare it the way I prepare a felony.
After an Arrest
Criminal cases in DuPage County follow a familiar path. Knowing it ahead of time helps you make better decisions at each step.

Illinois no longer uses cash bail. A judge decides whether you are released and on what conditions. Having a lawyer there matters.
The charges are formally filed and you enter a plea of not guilty. Felonies go through a grand jury or a preliminary hearing.
I request the police reports, any body camera and squad video, lab results and witness statements, then look closely at how the case was put together.
Motions can keep improperly gathered evidence out. Negotiation can reduce charges or open the door to supervision or diversion.
Many cases resolve by agreement. When one shouldn't, trial in front of a judge or jury is a real option, and I prepare for it from the start.
A criminal charge can trigger reporting duties and licensing reviews that move on their own schedule. Every case and every licensing board is different, so from the first call I ask what your job requires and plan the criminal case with that in mind.

Reviews
I was in need of some serious legal assistance recently. It really was not looking good for me. Pat Weiland is the best. He personally advocated for me to the state and I got my best possible outcome. I honestly can say Pat is a friend now. He turned a terrible situation around completely.
Pat Weiland is probably one of the nicest most knowledgeable and helpful Lawyers servicing DuPage county…. I have had my fair share of run in with Law Enforcement and just got my case resolved. Thank you sir!
Pat helped my brother, and now he’s helped me with my case at a reasonable price. I highly recommend him.
Where I Practice
My office is in Oakbrook Terrace, off Butterfield Road. DuPage County cases are heard at the DuPage County Courthouse and Administration Building in Wheaton, the same building where I spent my career as a prosecutor.
