Judge Gregory E. Mize

Judge Mize is a judicial fellow at the National Center for State Courts.   As part of NCSC’s Center for Jury Studies, he works to help state courts improve their jury trial systems.  He was project director of “Jury Trial Management for the 21st Century” which features a set of judicial education curricula focusing on jury selection and jury deliberations.  

Judge Mize served on a US Justice Department project to help the Republic of Georgia initiate criminal jury trials.  His tasks included running mock jury selection exercises for judges and lawyers in anticipation of the first homicide trials in late 2010.

President George H.W.

Jury Project, resulting in issuance of “Juries for the Year 2000 and Beyond” containing proposals to improve jury practices in the Superior Court and the U.S. District Court for the District of Columbia. 

His writings include: “Tough Cases” (The New Press 2018); “Jury Trial Innovations Across America: How We Are Teaching and Learning from Each Other,” 1 J.

As a member of the ABA American Jury Project, he contributed to the drafting of the ABA Principles for Juries & Jury Trials.

Before joining the trial bench, Judge Mize was a trial lawyer and then General Counsel to the District of Columbia City Council.  He is an adjunct professor at the Georgetown University Law Center.
