San Francisco 49ers season ticket holder Amir Kazemzadeh, backed by the Fan Freedom Project, is suing the National Football League team for violating federal antitrust laws with a new ticket resale policy that took effect this season. The policy requires anyone selling tickets over three days before the game to sell them via Ticketmaster, incurring significant fees. Kazemzadeh says the new policy represents "anticompetitive practices to dominate and restrict ticket sales." Ticket resales for a team as popular as the 49ers can be highly profitable, but the new policy will force buyers and sellers to pay a 15 percent fee to the NFL Ticket Exchange run by Ticketmaster. The policy also prevents ticketholders from gifting or donating tickets. The suit was filed as a proposed class action on behalf of all season ticket holders to the upcoming 2015-16 season. The Fan Freedom Project backed a similar suit in March by the ticket reseller StubHub against the Golden State Warriors. The suit seeks a court order barring the new policy as well as unspecified damages; a representative from the 49ers was not immediately available for comment.
