From what I've read, this challenge will likely fail. For one it doesn't include a TRO (Temporary Restraining Order) to really stop the law from taking effect. It also is only at the lowest level court, and according to other lawyers it's being filed incorrectly.
Sounds like it's going to fail. I hope not but it doesn't look good.
Which challenge? Is the judge not showing some degree of confidence in the case's merits to specify a date by which the state need defend itself lest an injunction apply?
