As a lawyer myself, I see this as nothing more than financial dispute. Bringing claims of harassment and retaliation won't survive if she isn't an employee. An employment relationship is a prerequisite, she herself admits she was a 1099 contractor and not an employee. At best, these are breach of contract and copyright claims. The employment/harassment related claims are to attempt to gain leverage and are likely just salacious in nature (and could potentially invoke a reimbursement of attorneys fees in California). I suspect GNR/Lebeis will file a demurrer motion to this complaint rather swiftly.
This case will probably be settled out of court fairly quickly. It's a typical business dispute, these things happen all the time in business and GNR, touring, and music industry is no different. I will add that I read the complaint by Benzova's lawyer, it was pretty sloppy, and he's been licensed for only ONE YEAR. He will be outmatched. Not to say her claims don't have some merit, I wouldn't know that one way or another. But just because she alleges things doesn't make them true. She could take any little off color joke made in the last 7 years of touring, and spin it to look salacious and bad. Curious to know whether she played along and made any jokes or innuendos along the way... Hell hath no fury like a photographer scorned!
