Yes. It's hard to say, because sometimes there have been individual lawsuits that were also dropped.
In my former employment as military ombudsman, I was involved in a case in which the Suffield guinea pigs--the ones who were sprayed with mustard gas during World War II--had been fighting the government for 50 years. They launched a class action lawsuit, and when we initiated our investigation and wrapped it up, they dropped the lawsuit, which was a huge lawsuit involving lots of money--millions and millions of dollars--in Federal Court. Again, it demonstrated the value of the intervention of an ombudsman's office.
