The Georgia Supreme Court will hold its first oral arguments in the new $131 million, 215,000-square-foot Nathan Deal Judicial Center Tuesday—hearing murder appeals and a civil challenge from consultants who help mothers establish breastfeeding.

Chief Justice Harold Melton will take notice of the occasion with remarks before the lawyers start their arguments for the 10 a.m. session, the court's public information officer said Friday. The building is at 330 Capitol Ave. S.E. at Memorial Drive, on the site once occupied by the state archives building.

The high court will hold forth on the top floor of the six-story building. Workers were still putting the finishing touches on the courtroom last week, even as visitors popped in and out escorted by justices and staff members.

The Georgia Court of Appeals held its first oral arguments Tuesday in the intermediate court's new second-floor courtroom.

Both courtrooms have entrances from the balconylike hallway circling a six-story atrium. Opposite both courtrooms are arching windows facing the Capitol's gold dome.

Both courtrooms feature blue carpet with gold stars, a dark wood bench accented with columns, backlit decorative ceiling recesses, the latest technology and much-improved acoustics.

In the morning session, the high court will hear two murder appeals and a challenge to a state law filed by lactation consultants.

In the latter case, Mary Nicholson Jackson, founder of a nonprofit called Reaching Our Sisters Everywhere (ROSE) is appealing from the dismissal of her lawsuit alleging that the 2015 Georgia Lactation Consultants Practice Act puts many of her colleagues out of business, preventing them from helping new mothers get started breastfeeding their babies.

In a 2 p.m. session, the high court will hear arguments in three appeals of murder cases.

Construction on the new building started in August 2017. The two appellate courts moved in during December. A formal dedication ceremony is set for 10:30 a.m. on Feb. 11. Former Gov. Nathan Deal is expected to speak, along with other state officials.
