If it was recorded in Georgia, it was legal. If it was recorded in Florida, it was illegal. But even then, one would need to do research into Georgia law to see if it would be excluded. Bartnicki v. Vopper, 532 U.S. 514 (2001) might also come into play. (That case involved a third party who intercepted a cell call illegally and provided it to a reporter).
Georgia law doesn’t require that the recording be made in Georgia, just that one party consented. Interesting legal issue that may not have yet been addressed.
Ransom v. Ransom 253 Ga 656 (1985) does give a broad reading to the statute (but see the dissent) but is not clearly on point.
If you have any good legal authority for the assertions made in the thread, I’d be interested in seeing them and am happy to revise my views based on any controlling legal authority, and at least re-visit them based on persuasive legal authority.
The law gets very interesting when the call is across state lines.
Your comment that the law in the state where it was recorded prevails is not necessarily true. See the case I posted sbove.
