According to this Roanoke Times article by Kevin Miller and Tonya Moxley: "An anti-war couple from Blacksburg is challenging the constitutionality of a Virginia law that blocks young men from obtaining a driver's license unless parents pre-register their sons for the military draft."
The article notes that the Virginia law passed in 2002 "requires males younger than 18 to have a parent or guardian authorize the DMV to forward their information to Selective Service, which will register the men once they turn 18. A parent's signature is required for a learner's permit, driver's license and photo ID."
Strangely, the suit was filed in state court in Montgomery County, which seems an unlikely venue. The Commonwealth is represented by Jasen Eige, formerly a SW Virginia lawyer himself.
