Here is the opinion. The court rejected other challenges to Georgia law as well, but the extension of the time for receipt of ballots is significant given how late Georgia voters can request and receive absentee ballots and given potential delays in having USPS deliver ballots on time. AJC says “The decision will likely result in tens of thousands of ballots being counted after Nov. 3 that would have otherwise been rejected, enough to swing close elections.”

AJC also says the state will immediately appeal, and I think there is a fairly good chance of a reversal of the extension time granted by the district court.
