In a late Friday filing in the Austin, Texas federal court, Musk rejected the claim the giveaway was an illegal “lottery” that violated a Texas law against deceptive trade practices.

Arizona resident Jacqueline McAferty claimed that Musk and his political action committee America PAC falsely induced voters in seven battleground states to sign the petition by promising that winners would be chosen randomly.

According to Musk, however, voters were told they would be reviewed for an opportunity to earn the $1 million by becoming America PAC spokespeople.

This, Musk said, defeated any notion that the money was a “prize” to be won.
