Experts in state ethics laws said last week that a veiled donation of $1.3 million being used to support J. Michael Wiggins’ candidacy for the Georgia Supreme Court demonstrates the limits of Georgia laws designed to identify whose money is influencing state elections.

The donation came in four October installments from the American Justice Partnership, an affiliate group of the National Association of Manufacturers, to the Safety & Prosperity Coalition. The coalition, an independent group not bound by the $5,000-per-individual-donation limit on candidates, has bought TV time in Georgia to run ads attacking Presiding Justice Carol W. Hunstein and promoting Wiggins, her challenger.
