This is a trick developed by Stefan Lanka, who is a close associate of Samuel Eckert. He has already created an identical reward for isolation of the measles virus. Under German law, they do not actually have to pay the reward.
The vaccination opponent was right, for formal reasons. The sponsor wanted a single piece of work with the evidence, but the plaintiff had delivered several publications that only provided evidence in total. Hence: "The appeal is essentially granted."
They demand only a single experiment to prove everything, but obviously, even if you show them the entire structure of the virus, they would want further proof that it's the same virus that makes people sick. Science relies on collaboration and independent verification and a single experiment would never suffice as proof that the virus is the same one circulating in the general population. Therefore, they will never have to pay.
