A brief summary: lawyers for Twitter were busy obfuscating and dissembling to the judge, pretending that Twitter was completely unable to formulate a SQL query to identify multiple accounts used by the same device and otherwise playing dumb, trying to throw enough technobabble to confuse a judge. The lawyers were also assembling a bunch of nonsense 1st Amendment arguments and hurling those at the wall too, hoping something would stick.
The judge and prosecutors were not fooled. Eventually the judge fined Twitter for all their nonsense.
So, contrary to some of the comments posted here already about dumb judges or whatever, this case shows a judge seeing through a bunch of techno-nonsense that lawyers tried to use to sow confusion.
