Howlin' Wolf has brought a lawsuit against StubHub. The music venue in New Orleans is taking action. It involves speculative ticket sales. Tickets were offered on StubHub before the venue confirmed them. StubHub functions as an online ticket resale marketplace. Speculative sales occur when sellers list tickets they have not acquired. Howlin' Wolf says this took place without approval. No more details have been given. The lawsuit aims at this kind of early listing. StubHub permits resales, but this case challenges the schedule.
