"World Bank Fraud"

I am intrigued by this part of a response by pafalafa-ga to an earlier question:

"The protection isn't absolute, however, and there have been a few
cases against the Bank -- mostly employee-related -- that have been
recognized as legitimate by the US courts."
...
"But if you wanted information about the relatively small number of
suits that have gone forward against the World Bank, I can certainly
provide that as an answer to your question."

As a former - and very disgruntled - World Bank employee, I would have
an action for Breach of Contract and related actions. I might also be
considered considered a whistleblower. I would like to know of the
cases referred to above.
