Pwnsall, previously we discussed the constitutionality of imposing a mental health certification requirement as a pre-condition of firearms licensing.
I just came across an
opinion from the 11th federal circuit which makes it the latest of 6 circuits (and thus a majority, not counting D.C.) to hold that the "prior restraint" doctrine under the 1st amendment does not apply to the 2nd amendment.
The "prior restraint" doctrine basically provides that Congress cannot bar the practice of otherwise protected speech before-the-fact of its occurrence, ie through licensing.
