Congressional Testimony

  Warner as been involved in some of the largest state investigations in Michigan in the past decade. In one case, Warner collected, reviewed and produced millions of documents in response to subpoenas and FOIA requests from the state Attorney General, Department of justice, Congress and nearly every major news organization in the country. The Warner team assisted with witness preparation — including testimony before Congress — and ultimately the defense of criminal charges.

Historical Sexual Abuse

  Warner attorneys have become the go-to source for assisting organizations with the prevention of sexual abuse and resolution of historical cases of sexual abuse. Warner attorneys have helped religious organizations audit files, update policies and procedures, conduct investigations into allegations of current and historic abuse, and defended organizations and its employees against potential criminal charges and civil liability.


  Our attorneys routinely investigate and counsel clients regarding allegations of fraud. From the first allegation to the final step in the appellate process, Warner is by our client’s side to provide you with guidance and, if needed, a rigorous defense at trial. Recently, we represented an organization accused of providing false information to the Government in relation to federal defense contracting. The organization not only escaped criminal indictment but also avoided any bar from government contracting.

Federal Firearms

  Members of the Warner team obtained a not-guilty verdict on all counts following a week-long federal jury trial. The Government had alleged that the individual defendant had violated various provisions of federal firearm law by possessing a certain class of firearm. The Warner team successfully convinced the jury that the Government was incorrect and obtained an acquittal.

Controlled Substances

  Our attorneys have handled dozens of matters involving controlled substances. In recent years, we have been lead trial counsel in one of the largest methamphetamine conspiracies in the history of the Western District of Michigan, have tried Title III wiretap cases involving the distribution of narcotics, and regularly advise clients on the tricky interplay between state and federal marijuana laws.

Appellate Expertise

  In 2020, our attorneys secured a landmark victory from the Michigan Supreme Court in a criminal case that could reshape police procedures. For the first time in history, the Michigan Supreme Court has held that improper police procedure in obtaining an eyewitness identification required the defendant to be granted a new trial. This decision affirms a criminal defendant’s constitutional right to have law enforcement use a proper lineup in the suspect identification process.

What We See On the Horizon

Contact your Warner White Collar Criminal Defense team for insight into these and others issues:

  • Cannabis. Reducing the prevalence of illegal narcotics has long been a priority for both state and federal law enforcement. Although Michigan has legalized the use of cannabis in some circumstances, marijuana remains illegal for all purposes and in all places under federal law. Our attorneys can help you navigate this complicated legal framework to keep you on the right side of the law.
  • Renewed Focus on False Claims Act and Fraud Prosecutions. Whether it is mail fraud, bank fraud, PPP loan fraud or false statements in connection with the receipt of federal money, the federal government continues to focus efforts on criminal prosecutions and civil lawsuits. Warner’s team has extensive experience conducting internal investigations and audits, responding to civil and criminal document requests, preparing witnesses and defending individuals and companies accused of these offenses. And we keep our eye on trends in these prosecutions to help alert our corporate clients to areas of focus for the Department of Justice and state authorities.
  • Easing the Burden of Document Review. As technology evolves and our lives revolve around greater use of that technology, the burden of responding to subpoenas and document requests increases. Our attorneys understand that cost is one of the driving concerns for our clients. Fortunately, we serve you with a constant eye on your legal spend and do all we can to lower the price tag of responding to grand jury subpoenas, civil investigative demands or other governmental document requests.

“As counsel for the Diocese of Grand Rapids, Madelaine Lane has provided us outstanding service with her keen legal acumen and forthright guidance. Her professional character, excellent communication skills, and community engagement clearly merit her for consideration as a most notable attorney in West Michigan.” – Monsignor William H. Duncan, Vicar General, Diocese of Grand Rapids


“As a juror in your recent federal criminal trial, I wanted to express that I very much enjoyed listening and watching your examination of the witnesses. At one point I wanted to cheer for you as you concluded! I thought all the attorneys were great ─ but I just truly enjoyed your work. You are an inspiring trial attorney and a female role model!!” – Juror from a federal criminal trial (in reference to Madelaine Lane)


“As a survivor of human trafficking, I had charges on my record that could not be expunged due to the severity of the crimes. The crimes were committed while I was under a pimp’s control, which meant that whatever I was told to do I did, or else got beaten. Once I was out of that life and free, I founded the very first survivor-led peer mentorship program in the state of Michigan assisting victims of trafficking in reclaiming their lives and working to become productive members of society.

I went to college to become a social worker but was told that I could not get licensed due to my criminal background. I felt devastated and defeated. My criminal record still haunted me at every turn. And, twenty years later, I tried to get an expungement and was denied over and over again. I was then introduced to an attorney by the name of Madelaine Lane who works for Warner Norcross + Judd. Upon speaking with Madelaine concerning my past I was a little embarrassed and untrusting of others. Right away Madelaine put me at ease which allowed me to speak with her about my life and experience being trafficked.

Madelaine did the paperwork to get my record expunged and sent it to the necessary entity. Several weeks later I received a call from Madelaine stating that it was rejected but before I could speak, she said “Let’s go for a pardon.” I said okay, but was not enthused because of all the prior rejections.

Several days before Christmas of 2022, I received a call from the governor’s office stating that the governor had granted me a pardon! All I could do was scream while tears of joy ran down my face!

Without the excellent work of Madelaine Lane, none of this could have been possible. Madelaine I would like to thank you once again for all your hard work and perseverance concerning my case. I can finally say that I am FREE.” – Leslie King
