EXACTLY! That is within the authority of the Board of Directors and since Scott received shares from the previous board his performance justifies revoking them. It is then up to him to go to the courts and I want to be in that room seeing him defend his performance.
If there is wrong doing on Keevil's part and The Board has PROOF, they can pressure Keevil to voluntarily return some or all of his shares or suffer the consequences of possible criminal action. Further, the Keevil family may be a source of additional pressure on Keevil to "do the right thing", as they will certainly want to avoid a scandal that could besmirch the family name.
