Michael devotes a significant amount of time to pro bono matters, including participation in the firm’s Capital Litigation Project, in which Sidley lawyers across the country represent prisoners on death row in the State of Alabama. For nearly 10 years, Michael represented inmate William Ziegler in a collateral review proceeding challenging his capital murder conviction and sentence. In November 2012, the Circuit Court for Mobile, Alabama, vacated Mr. Ziegler’s conviction and granted him a new trial, finding numerous constitutional violations in connection with his original capital murder trial. In April 2015, Mr. Ziegler was released from prison following a plea agreement with state prosecutors. This important case was reviewed in several articles in the Mobile Press Register, including: “How the system failed William Ziegler: Perjured testimony, trashed evidence, lying jurors,” and “Former Alabama Death Row inmate cuts deal, free after 15 years in prison.” Mr. Ziegler’s case was also mentioned in an article listing Sidley among Law360’s top Pro Bono Firms of 2014.

Michael has also been involved in other noteworthy pro bono criminal matters. In 2014, Michael helped obtain a significant victory for firm client Robert Medina, when, after a three-week trial, a jury sitting in the Southern District of New York acquitted Mr. Medina of federal murder charges as well as certain related weapons and narcotics conspiracy charges for which he would have received a mandatory minimum 45-year prison sentence if convicted on all counts (United States of America v. Medina, S2 13 Cr. 272 (PGG)). At sentencing the trial judge noted that: “This is one of those cases where I think one can say with some degree of certainty that the work of defense counsel led to a result which may well not have been achieved by different counsel.”

Michael’s pro bono work extends outside of the criminal context. He has represented individuals facing persecution in their home country obtain asylum in the United States, low-income artists in legal matters to protect their creative work, and non-profit organizations in a wide array of legal and business disputes. In one noteworthy case, Michael represented the Turning Point Foundation, a non-profit that operates group homes for individuals recovering from drug and alcohol addiction in disability rights litigation against the City of New Haven after the City attempted to use its zoning enforcement power to exclude the Foundation from residential neighborhoods in alleged violation of the federal Fair Housing Act and the Americans with Disabilities Act. As part of a settlement, the City of New Haven agreed to allow the Foundation’s residents to remain in their homes, to pay $350,000 in damages and lawyers’ fees, and to work with the Connecticut Fair Housing Center to improve the City’s compliance with federal law.
