Howlin' Wolf has brought a lawsuit against StubHub. The music venue in New Orleans is pursuing a case. It focuses on speculative ticket sales. Tickets were listed on StubHub before the venue verified them. StubHub functions as an online ticket resale marketplace. Speculative sales happen when sellers post tickets they don't own yet. Howlin' Wolf says this occurred without approval. No more details have been given. The lawsuit targets this kind of advance listing. StubHub allows resales, but this case challenges the timing of listings.
