Gov. Andrew Cuomo’s message of necessity that skirts the three-day waiting period so lawmakers can pass his gun control legislation this week outlines what his office says is the immediate need to get the law in place.

“Some weapons are so dangerous, and some ammunition devices so lethal, that New York State must act without delay to prohibit their continue sale and possession in the state in order to protect its children, first responders and citizens as soon as possible. This bill, if enacted, would do so by immediately banning the ownership, purchase and sale of assault weapons and large capacity ammunition feeding devices, and eliminate them from commerce in New York State.”

The measure, which passed the Senate last night 43-18, will be voted on by the Democratic-led Assembly this morning. The bill updates the state’s assault weapons ban, reduces the number of bullets in a magazine from 10 to seven and strengthens criminal penalties for illegal guns.

Cuomo last night speaking to reporters said he usually tries to avoid messages of necessity, but the spate of mass shootings required swift action. Cuomo’s use of messages of necessity has come under criticism, most recently after he issued messages in order to swiftly pass a package of bills including a new, less generous pension tier.

If the Assembly passes the bill today — and it appears that it will at this point — New York would be the first state to enact a new gun control law in the wake of the Connecticut school shooting that killed 20 children.
