Landmark Cases
Soon after taking office, Greg was approached by the adult children of a murder victim, whose case had been rejected for prosecution by Greg's predecessor. Rather than take the easy path and leave it closed, Greg reopened the case, worked with detectives to conduct more investigation, and ultimately secured a jury verdict of guilty against Linda Miley.
State v. Miley
In 2015, county commissioners sidestep the elected prosecutor and hired expensive private lawyers. Greg challenged the move all the way to the Washington Supreme Court. In a unanimous 9–0 decision, the Court issued a landmark decision agreeing with Greg. The Drummond case has been relied on by many courts since it was handed down, showing its importance in strengthening checks and balances, and preserving the people’s right to choose their county prosecutor.
State ex rel. Banks v. Drummond
After the Washington Supreme Court’s Andress decision reversed over 300 murder convictions going back 25 years, Greg was chosen by prosecutors in King, Pierce and Clark County to argue five consolidated murder cases. In State v. Gamble, he helped convince the Supreme Court to allow many of those hundreds of murderers to be retried, restoring justice for victims’ families.
State v. Gamble
Greg prosecuted a man who unlawfully entered a ballot counting room in violation of the Auditor's rules protecting election workers and fair elections. Despite an intense social media campaign, and personal threats against Greg and his family, he stayed focused on the rule of law and the importance of orderly, secure elections. Greg fought back multiple challenges by the defendant's three lawyers, and convinced 12 jurors to unanimously find the election disrupter guilty.
Election Integrity
In 2017, Greg was selected by the National District Attorneys Association to attend proceedings at Camp Justice in Guantanamo Bay, Cuba, as a prosecutor-observer in the case against Abd al-Rahim al-Nashiri, who is charged with planning and executing the bombing of the U.S.S. Cole in 2000.
