COLUMBIA, S.C. (AP) A state agency broke the law when it shut out the river commission from negotiations over dredging the Savannah River, the top justice on South Carolina’s highest court argued Tuesday, saying the agency “rubber stamped” an agreement with Georgia officials on the project.

“You disobeyed the law when you did not involve the Savannah River Maritime Commission in the settlement of this matter,” Chief Justice Jean Toal said to John Harleston, an attorney for South Carolina’s Department of Health and Environmental Control, during a hearing.
