Client Testimonials

Kind words from former clients.

Mr. Maze was great! I had a racially sensitive case involving a hit and run and William was able to locate overlooked evidence, he called out multiple injustices and did everything in his power to win a case that was set up to lose. I am very satisfied with the outcome of my case.

A lawyers lawyer!
This is a new one for me as I have reviewed William professionally as him and I both practice criminal defense and conduct far more jury trials than the average criminal defense attorney. Part of knowing William is that I know he handles freedom of information act cases. So when I needed to sue the city of Dearborn for failing to provide me discovery in a case I was handling after I had foia'd it, I knew there was only one person to call. William took my case and immediately filed a complaint against Dearborn. After about two weeks of denials, William forced their hand and was able to obtain all of the secret documents unlawfully kept from me. In essence, he uncovered a major coverup by the City of Dearborn. These records included videos of the incident as well as a lengthy secret police report. The circuit court judge eventually ruled that because Dearborn had given me what they represented was 'everything,' the case was dismissed over William's very forceful written and oral objections. Rather than stop there, William filed what can only be described as the nuclear bomb of appellate briefs on the City. The Court of Appeals in a split decision, denied our relief. Undeterred, William kept up my confidence and filed a killer brief in the Michigan Supreme Court. And then a funny thing happened.....In one of the more rare things that can take place in the Supreme Court, the court in a unanimous memorandum opinion, reversed the circuit court and court of appeals and rules completely in my favor. A memorandum opinion is rare because it only takes place when the court judges are so convinced that one party is correct, that they rule on the case without having oral arguments! Now if you type in James Amberg v City of Dearborn in google, you can read the end product of William's fearless work and dedication to his clients and his job as a lawyer. He singlehandedly changed the law for foia in Michigan much to the benefit of us, the citizens. As a lawyer who wins a lot of cases and tries hard to win every case I take, I can honestly say that if you need a lawyer who will fight for you when the chips are down and is not afraid to stand up to the unfairness of the legal system, you only need to make the call to William Maze.

When dealing with the legal system you need a lawyer to ensure the best outcome for your situation. In my case, that was a complete dismissal. Working with William, I felt confident that I was being represented by the best, beginning from the first time we talked. Thanks a lot William.

Mr. Maze was extremely helpful with guiding me through the process, and also got the charges lowered. You can tell from his interactions with his peers that he is highly respected and knows the system well

Should You Take a PBT?

A roadside breath test is a civil infraction. My advice is to refuse it, but others disagree with me. Learn why.

Should You Submit to Field Sobriety Tests?

No. You always fail field sobriety tests, no matter how well you perform the tasks. Worse still — you always look guilty trying to perform FSTs.

Drugged driving is the newest buzz word in Michigan drunk driving enforcement. It is a money grab designed to criminalize drivers taking prescription medications.
