Philippe Dauman, president and chief executive officer Viacom Inc., arrives to a morning session during the Allen & Co. Media and Technology Conference in Sun Valley, Idaho on Thursday, July 10, 2014. 

The decision to remove nearly half of the Viacom board directors would still be valid even if Sumner Redstone lacks capacity or is being unduly influenced by his daughter, according to a letter sent Tuesday on behalf of the media mogul's trust.

"Based upon statements made by or on behalf of the Viacom Board in recent weeks, there is a clear lack of understanding regarding the authority under which National removed and replaced five of Viacom's eleven directors, and an apparent belief that attacks on Sumner Redstone's capacity or alleged ‘undue influence' would somehow undercut that authority," states the letter from National Amusements. "To help you understand why that is not the case, we offer a brief primer on National's governance."

Philippe Dauman Files Lawsuit Challenging Removal From Sumner Redstone Trust

Shortly after ousting Philippe Dauman and George Abrams from the trust, the directors voted to shake up Viacom's leadership. Redstone’s eight-page letter lays out how and why those board members would have been replaced, even if Dauman and Abrams hadn't been removed as trustees first. In a nutshell: They would have been outvoted. 

Fred Salerno's lawsuit alleging Shari Redstone is breaching her fiduciary duty also is addressed in the letter.

"Needless to say, these highly personal and vicious attacks on Sumner's capacity and Shari's honesty and integrity are offensive and unacceptable," states the letter. "More importantly, however, those allegations, even if they could somehow be proven, would have no impact on the legitimacy of National's actions with respect to Viacom."

Philippe Dauman Argues Trustees' Ratification of His Removal Isn't Significant

Two scenarios are spelled out for the readers, one in which Sumner has capacity and the other in which he does not, and both have the same end result. 

"In short, however the attacks on Sumner's capacity or alleged undue influence might be resolved, National's removal and replacement of five of Viacom's eleven directors will not be disturbed," ends the letter.

A Viacom spokeswoman responded with a statement Tuesday afternoon: "In today's letter, the supposed directors of National Amusements have claimed that Sumner Redstone's incapacity or undue influence does not matter. It matters a great deal to Viacom's shareholders and Viacom's board if Sumner Redstone lacked capacity or was unduly influenced in the making of recent and dramatic governance changes. Under the law, the implications would be grave if a Court were to rule that recent changes were infected by Shari Redstone's undue influence and any improper acts allegedly in Sumner Redstone's name. Any ‘vote' made under these circumstances would be meaningless. Individuals who have taken part in such a scheme could and should be ruled unfit to serve as trustees or board members."

Embattled Viacom CEO Philippe Dauman Takes His Case to the Company's Employees

Earlier this week, Dauman filed papers in a Massachusetts court where on Thursday a probate judge will be asked to allow him and Abrams to legally challenge the way they were removed from the trust. Dauman and Abrams argue that issues related to the trust, including the question of undue influence on Redstone by his daughter, must be adjudicated in Massachusetts because that is where the trust was set up, that's where it is administered, and that's where the records are kept.
