What were the two environment campaigners claims against McDonald’s?

M: Do you like McDonald’s, Amy?
F:  Just so -so. Why ask this?
M: Well, do you know that some environment campaigners sued the world’s largest fast-food chain? They claimed that the food carries health risks and McDonald’s workers suffer poor pay and conditions. They say that eating the company’s hamburgers can cause heart disease.
F:  Hm, I think if one eats enough McDonald’s food, one’s diet may well become high in fat with the very risk of heart disease, so the claim is justified. Who are these environmental campaigners?
M: They were Helen Steel, aged 34, and Dave Morris, 44. In 1997,the High Court in London found them guilty of distributing a pamphlet containing allegations against McDonald’s and their fast food and its preparation.
F: What was the result of the trial?
M: The trial lasted three years. Finally the High Court in London awarded McDonald’s damages of 60,000 pounds against the two penniless campaigners.
F:  You mean McDonald’s hasn’t yet recovered a penny from the campaigners.
M: No, they refuse to hand over any money even after in 1999, three Appeal Court Judges in London decide that the two would have the damages they have to pay to McDonald’s reduced to 40,000 pounds.
