From Rochester Democrat and Chronicle:

The decision Monday by the U.S. Court of Appeals for the Second Circuit found that the SAFE Act in New York and laws in Connecticut following the Sandy Hook Elementary School shooting in 2012 do not infringe on the Second Amendment, as gun-rights groups contended in their lawsuits.

“We hold that the core provisions of the New York and Connecticut laws prohibiting possession of semiautomatic assault weapons and large-capacity magazines do not violate the Second Amendment, and that the challenged individual provisions are not void for vagueness,” the court ruling states.

From American Thinker:

The SAFE (“Secure Ammunition and Firearms Enforcement”) Act was presented to the New York State Senate and passed into law in 15 minutes.  No debate was allowed, and senators did not have time to read the bill before voting it into law.

The SAFE Act is a complete ban on the sale or transfer of all military-style semi-automatic rifles manufactured within the past several decades.  It is a total ban on the AR-15, AK-47, M-14/M-1a, HK G3, Steyr AUG, and many other civilian copies of military firearms.  Prior to the passage of the law, Gov. Cuomo publicly stated that he was considering “confiscation” of existing rifles, but the final version of the law allowed existing owners to keep their rifles as long as they registered them with the State.  Upon the death of the owner, the rifle will be confiscated; it cannot be transferred to an heir within New York State.
