Please. I have obtained dozens of temporary restraining orders and preliminary injunctions.
Think about what you wrote. The injunction is not granted unless the movant is likely to succeed at trial on the merits. Meaning that the “substantive” part of the case is not close. Its an easy call for the judge. Like I said.
As for the Christian Legal Society v. Walker case, I do not see the Supreme Court reversal your claim.
Citations to your “dozens” of injunctions?
