The Hall County Board of Tax Assessors is appealing a Superior Court ruling regarding five companies’ shoreline properties and their tax assessments, arguing a 2016 law strips the court’s power. The board’s case will be argued at 2 p.m. Tuesday at the Supreme Court of Georgia in Atlanta. The case involves Westrec Properties, PS Recreational Properties, Chattahoochee Parks, March First and AMP III-Lazy Days, all companies leasing marina property on Lake Lanier.
