Willis Law Firm & the U.S. Supreme Court
A Record No Other Georgia DUI Attorney Has
The United States Supreme Court receives approximately 7,000–8,000 petitions for certiorari each term. It grants fewer than 100. Having a case accepted — or even filed — at the Supreme Court is a distinction that almost no attorney in the country ever achieves. Greg Willis has done it multiple times. In DUI defense.
Unanimous Victory
McElrath v. Georgia (2024)
Greg Willis filed the winning amicus curiae brief in McElrath v. Georgia on behalf of the Georgia Association of Criminal Defense Lawyers (GACDL). The U.S. Supreme Court issued a unanimous decision holding that a verdict of ‘not guilty by reason of insanity’ constitutes an acquittal under the Double Jeopardy Clause of the Fifth Amendment. The ruling has significant implications for defendants in Georgia who face re-prosecution after a mixed verdict. [External link: Supreme Court opinion]
Pending Petition
La Anyane v. Georgia
Greg has filed a petition for certiorari in La Anyane v. Georgia, challenging the constitutionality of Georgia’s implied consent statute. The petition asks the Supreme Court to address whether Georgia’s implied consent framework — which allows prosecution of DUI refusal — violates the Fourth Amendment. This case builds directly on the 2019 Georgia Supreme Court ruling that Greg previously won on implied consent grounds.
Active Petition
Johns v. Georgia (No. 25-689)
This petition, filed as No. 25-689, is currently before the United States Supreme Court. It represents the continuation of Greg Willis’s appellate practice at the highest level of the American legal system.
Additional SCOTUS Filings
Prosecutors throughout Georgia know who Greg Willis is. They know his cases are thoroughly prepared, aggressively litigated, and taken to appeal when necessary — including to the United States Supreme Court. That knowledge changes what prosecutors offer before trial. It changes how judges rule on close questions. It changes the entire posture of a case. This is not theoretical. It is a documented competitive advantage that directly benefits every client Willis Law Firm represents.
