I would agree, however, any company can declare a "special" dividend to compensate shareholders owning shares on X date. This is not a court issue..the board of directors makes that decision.
If Nader was selected to the Board of Directors, after Cship ends, of course, then he could compensate "long term" shareholders by declaring a special dividend on xx-xx-2010.
IF you owned the stock on x dividend date declared by the board, then you get the divie, like always. Its a board issue and decision, not one that needs to be tried in the court of public opinion.
Board of directors should make their intentions known so that shareholders can vote which board member more closely aligns with their interests. If the board decisions do not reflect a consensus of the majority of shareholders, then the shareholders can install board members consistent with their objectives. This is the way it works. Obviously, each share has one vote, so "big" shareholders have a powerful influence. Sometimes, a shareholder can buy 10% or less of the stock, then convince another 41% of the voting shareholders to side with him, and he can effectively control the company with 51% of the vote.
