Orleans Parish Criminal District Judge Keva Landrum-Johnson is now the court's chief judge.
Landrum-Johnson took over the two-year position from Judge Laurie White with the New Year. She is the first black woman to assume the court's top post.
The chief judge oversees the court's administrative functions and sits ex-officio on its committees. Landrum-Johnson, 44, is one of 12 district judges at Tulane and Broad.
The chief judge post rotates based on seniority. Landrum Johnson won election to the bench in 2008, taking the Section "E" seat left vacant when former Judge Calvin Johnson retired.
Her lone opponent in that race dropped out early, and Landrum-Johnson retained her seat unopposed in 2014.
She assumed the bench after serving for a decade as an Orleans Parish prosecutor, including a stint as the acting District Attorney after former DA Eddie Jordan resigned under political fire in 2007.
"Orleans Parish Criminal District Court is one of the most significant institutions in the City of New Orleans, and I am honored to have earned the trust and confidence of my colleagues to lead in this capacity," Landrum-Johnson said in a statement.
Landrum-Johnson is a native of New Orleans and a graduate of Ursuline Academy, Washington University in St. Louis and Tulane Law School.
