That may be true but the OP is at the point where no summary judgment has been filed (or if it did, it passed that hurdle); motions to strike have been gone thru and the case survived.
It is the client who decides to accept a settlement or not; its outrageous that an attny would behave in such a manner. And why wouldn't the attny allow the client to decide if the settlement amount is enough to settle -- this is not a decision for the lawyer -- he is in charge of litigation strategy, not of the decider on settlement.
I would tell the lawyer that you will file an objection to his motion to withdraw and that he can continue with settlement talks but that YOU have the right to accept any offer or not.
