Question

I filmed a wedding video for a client. They were unhappy with the quality of the video and have threatened to give me bad reviews everywhere they can think of unless I give them a full refund. Is demanding money in order not to give me a bad review illegal on their part? If so, can I sue them? The wedding took place in Illinois. They live in California. I live in Illinois

Answer

Their conduct is not likely illegal, and a lawsuit is not recommended.
