My guess is that the COS dealt directly with Marty and Monique, and left ALL of the attorneys out of it.
Thats really the ONLY theory we have any supporting evidence for.
Because they said, they had effectively achieved the purpose of the suit WITHOUT the help of their lawyers.
There really isn't anything else than could mean, if the stated purpose was to make the COS stop its harassment.
Without the help of their lawyers means exactly a behind the scenes agreement.
Some people would by necessity for clarity call that a settlement, but not Marty. That would make it too easy too understand.
