AB Value Partners LP v. Kreisler Manufacturing Corporation, C.A. 10434-VCP (December 16, 2014) Advance notice bylaws are valid under Delaware law. However, their application may be enjoined in rare circumstances when the Board of Directors has "radically" changed the playing field after the time to give notice of a competing slate. This decision gives examples of when that has occurred and more often, when it has not occurred. The burden to get relief a is high one and is not met by just a change in circumstances not caused by the incumbent Board.
