He'll be challenged and he'll lose and he'll cost the state a lot of money in the process," Todd said. University of Alabama School of Law Professor Ronald Krotoszynski agreed. He said that although it is technically true the state Supreme Court never withdrew its March injunction, "the U.S. Supreme Court plainly overruled it and federal courts would rule against judges who refuse licenses." "In light of this reality, ordering the state's probate judges to refuse to issue marriage licenses to all couples who seek them constitutes an exercise in futility," Krotoszynski said. "At best, it sows chaos and confusion; at worst, it forces couples to bring federal court litigation in order to exercise a clearly established federal constitutional right."

LAS VEGAS (AP) -- Chinese drone maker Ehang Inc. on Wednesday unveiled what it calls the world's first drone capable of carrying a human passenger.

The Guangzhou, China-based company pulled the cloth off the Ehang 184 at the Las Vegas Convention Center during the CES gadget show. In a company video showing it flying, it looks like a small helicopter but with four doubled propellers spinning parallel to the ground like other drones.

The electric-powered drone can be fully charged in two hours, carry up to 220 pounds and fly for 23 minutes at sea level, according to Ehang. The cabin fits one person and a small backpack and even has air conditioning and a reading light. With propellers folded up, it's designed to fit in a single parking spot.

After setting a flight plan, passengers only need to give two commands, "take off" and "land," each controlled by a single click on a Microsoft Surface tablet, the company said.

It is designed to fly about 1,000 to 1,650 feet off the ground with a maximum altitude of 11,500 feet and top speed of 63 miles per hour.

U.S. authorities are just starting to lay out guidelines for drone use, and a human-passenger drone seems certain to face strict scrutiny.

Federal Aviation Administration administrator Michael Huerta was at CES but could not immediately be reached for comment through a spokesman.LAS VEGAS (AP) -- Chinese drone maker Ehang Inc. on Wednesday unveiled what it calls the world's first drone capable of carrying a human passenger.
