"Maryland Governor Larry Hogan on Tuesday announced that he has directed the Maryland State Police to suspend the "good and substantial reason" standard when reviewing applications for wear and carry gun permits in the state. The order comes after the Supreme Court struck down a similar law in New York.
“Last month, the U.S. Supreme Court struck down a provision in New York law pertaining to handgun permitting that is virtually indistinguishable from Maryland law. In light of the ruling and to ensure compliance with the Constitution, I am directing the Maryland State Police to immediately suspend utilization of the ‘good and substantial reason’ standard when reviewing applications for Wear and Carry Permits. It would be unconstitutional to continue enforcing this provision in state law. There is no impact on other permitting requirements and protocols."
