Hmmmm? I don't think it's that easy to "withdraw" from a major lawsuit like that. Isn't there ususally some penalty if you withdraw ..??
I don't think you can file papers, take up the court's time, and then just say .. oh forget it, I've changed my mind and I don't want to do this?
You make an excellent point, Cyberant. In the federal courts, the "safe harbor" provision of Rule 11 leaves too much room for withdrawal of a frivolous suit without sanction. In state jurisdictions, the rules for this vary. Often, to avoid court sanction after the defendant has responded, the parties to the suit have to agree on terms of withdrawal.
