What area of law you an expert and why?

Constitutional Criminal Issues, particularly Fourth Amendment Search and Seizure issues.  The Fourth Amendment to the United States Constitution protects personal privacy, and every citizen’s right to be free from unreasonable government intrusion into their persons, homes, businesses, and property – whether through police stops of individuals on the street, in their vehicles, during an arrest, or searches of their homes or businesses.  The Fourth Amendment provides safeguards to individuals during searches and detentions; and prevents unlawfully seized items from being used as evidence in a criminal case.  I have worked on numerous state and federal felony cases wherein I have successfully written motions and supporting briefs for the suppression of evidence that was obtained in violation of the Fourth Amendment.

United States v Arreola-Alvarado, United states District Court Eastern District of Michigan Southern Division, Case No. 16-20748 – Motion Granted, “Neither the evidence seized from the Melrose Street residence, nor the statements made to the Drug Enforcement Agency (“DEA”) agents, can be used at trial against Mario Arreola-Alvarado.”  Case involved the suppression of 7 kilograms of heroin and 1 kilogram of cocaine.

State of Michigan v Jason Baker, Wayne County Circuit Court, Case No. 18-002123-01 FH, Judge Catherine Heise.  Case involved our client’s right against self-incrimination (Fifth Amendment to the United States Constitution) and a Miranda warning violation, which includes the right to legal counsel. .

State of Michigan v Daniel Marks, Wayne County Circuit Court, Case No. 2017-010691-01, Judge Timothy Kenny.  This case involved the exclusion of all evidence after officers and agents searched our client’s home, who was on felony probation, without reasonable cause.  Items illegally seized included, 4 pounds of marijuana, and $14,000 in US currency.

People of State of Michigan v Aaron Haywood, 76th District Court for the County of Isabella, Case No. 17-251SD, Judge Eric Janes – This case involved an unlawful stop of a vehicle and subsequent illegal search of the vehicle, unlawful arrest, and unlawful blood draw.

I also specialize in criminal defenses under the Michigan Medical Marihuana Act, including immunity under Section 4 of MMMA and asserting an affirmative defense under Section 8 of the MMMA.  Successful cases include the Baker case mentioned above, and People of the State of Michigan v Clyde Richard Lawrence, Wayne County Circuit Court, Case No. 18-001559-01-FH, Judge Qiana Lillard.
