Ok, we've swapped them in the title above. Thanks!
Not to mention which is the defendant that Apple is siding with...
Google is defendant
What do you mean? The US is not a defendant in this case, it's not ambiguous -- defendant just refers to the party/parties accused of a crime. You can have multiple defendants, but only one 'side' of the trial will contain any defendants -- the other side, the US in this case, is the plaintiff.
That's why it's important to list the parties in the correct order.
On appeals, cases are listed based on which is the appellant which is the respondent.
Right, they're saying that the title is misleading/ ambiguous because it confuses the order of defendant and plaintiff, so if you just read Apple's motion you'd be confused about which is which and who Apple is arguing with
Yes, they’re saying it was not clear who was the defendant in the title, it seemed like the US was.
