Technically, sure, but the warrant is valid for him. Wentzell ruled on it. The Appeals Court refused to grant interlocutory appeal. At this point he's taking a plea deal, or going to trial. He's out of pre-trial fuck-fuck games to play.
Meaning that, yes, it's possible for the unusual situation where the warrant is invalid for Kayla, but valid for Nick. I don't think that'll happen though. I think Wentzell will rule it's valid for Kayla too.
With both sides of the argument now submitted, Wentzell should make a decision soon.
