Howlin' Wolf has filed a lawsuit against StubHub. The music venue in New Orleans is pursuing a case. It involves speculative ticket sales. Tickets were sold on StubHub before the venue approved them. StubHub operates as a online ticket resale marketplace. Speculative sales occur when sellers advertise tickets they do not possess. Howlin' Wolf states this took place without authorization. No more details have been given. The lawsuit targets this kind of advance listing. StubHub facilitates resales, but this case scrutinizes the timing of listings.
