The Hall County Board of Commissioners is not guilty of any “prosecutable” violations of open meetings laws related to how it manages its agenda, the state attorney general’s office said after an investigation last month. However, the attorney general’s office said it will continue to monitor commissioners’ actions in light of questions raised about their meetings. The office initiated an investigation after becoming aware of a story and editorial in The Times questioning the practice of taking action on issues not listed on agendas provided to the public and media.
