NWBO had to change their behavior in a case that settled many years ago, but the case was dismissed with without prejudice, and I believe it was left available for plaintiffs to refile for a year or two if NWBO didn’t follow through. That case was eventually completely dismissed, because NWBO fulfilled their responsibilities.
This time, with NWBO as the plaintiffs, (and market maker defendants) such a
settlement procedure could leave intense scrutiny over Market Maker behavior after any potential settlement but before complete dismissal. Thus reducing spoofing opportunities — in theory — upon any approval decision or other positive news.
