The Georgia Court of Appeals has revived a putative class action that, if certified and successful, could mean tens of millions of dollars in refunds to residents of Fulton County and 14 cities within it who bought homes in 2015 and 2016 and were allegedly hit with illegally inflated property tax bills.

The plaintiffs allege that county tax assessors sought out recently sold properties and based their taxes on the sales price while leaving the assessments for comparable, unsold properties undisturbed, a practice known as "sales-chasing."
