After hearing three hours of arguments, Waukesha County Circuit Court Judge Michael Bohren determined state law allows absentee ballots to be returned in person or by mail — but not in a ballot drop box.
"It's all good and nice, but there's no authority to do it," Bohren said of the use of drop boxes.

So the judge is NOT saying there was any voter fraud involved.
He is not saying ballots were not being turned in and counted.
And personally I think the judge is wrong.
If the same security is applied to the drop boxes as is given to ballot boxes at polling places, then these drop boxes are just a convenience for voters, so they do not have to travel as far.
I would only be wrong if the mail in ballot boxes at polling stations had higher security, such as checking ID, that the remote drop box did not have.
