"just who else could there be? "
An excellent question, and one which serves to broaden the conjectural underlayment of this discussion. Just who else could there be? There are many directions of inquiry that are suggested by such a question.
As a first example, among the more obvious directions such an inquiry would follow, there exists the question of possible individuals who were peripherally involved in the wrongdoing, but who have managed to escape public mention thus far. Possibly, while appearing to be cooperating in the original plot, they were actually engaged in their own agenda running at cross purposes to those of the SLJB scam, and to those of the shareholders as well.
In this regard, one could examine the as yet unfollowed connections to Alberta. Who introduced the SLJB team to the concept of relocation to Alberta, and did they assist in laying some of the original groundwork for the move? And on the same token, did they then function to bring the matter of SLJB in front of the ASC quickly after the move to Alberta to thwart the success of the move?
The exploration of such a question might lead to the doorstep of one or more individuals who are as yet unidentified in the extant accounts of the SLJB saga.
Many other such paths, worthy of exploration, present themselves readily. The ongoing discussions on this board may, over time, provide the basis of further inquiries than those which have as yet been pursued.
