Thats an interesting and challenging question, at least for us as bystanders and/or customers of Bitcoinica, possibly bearing the losses :-/
Business is often comprised of "acting to the rules" while at the same time a lot is going on "in between the lines".
Often, some view, which, legally and by the rules is not 100% correc, is announced and repreated with great vehemence, thus putting the oposing side under pressure. It is difficult to judge the actual balance of powers from the outside. Also the personalities of the people involved do play some role (and we, as bystanders, don't know anyone of those actors in person).
Who is in the stronger position? Who was at the end of May, which seems to be the period where the further route of events basically was determined? Personally, from his insiting on the legal situation and also his urging to proceed with the payouts, it looks that Tihan was in the slightly weaker position (but not much weaker).
Tihan was technically right. I checked the other day on whether NZ law is the same as Australian law on this and it is. From the time the partnership agreement was signed (or the starting date specified in the agreement) Amir, Patrick and Donald were liable as general partners whether or not the paperwork had been completed for the formation of Bitcoinica Consultancy Ltd. This is because 1) there is a filing period for the paperwork, and 2) because even if someone is not named as a director of a company on the paperwork if they have been performing the duties of a director they are liable in the same way as a named director (I'll bet Chris Heaslip is super-pissed that this all went down while he was the only named director).
Tihan's argument was that if they didn't follow through with the formation of the company and take responsibility for the payout process, they would have abandoned their legal responsibility. The implicit threat in that it that they could then be
personally sued by just about everyone but especially the limited partner (who already had shares in Intersango, remember) - completing the formation of the company would limit their liability.
It was a carrot and a stick approach. If I had to guess, I suspect that the threats weren't idle. While VCs are obviously prepared for businesses to fail, this one fell at the starting gate. I'm quite sure that the limited partner would have negotiated a harsh agreement in order to remove litigation from the table. We'll never know for certain because even more calamity intervened.
This allows Bitcoinica LP to take over and hand the payouts process to us. Technically Bitcoinica LP owns the assets.
You guys are the general partner of Bitcoinica LP - whatever you do binds the partnership. If the limited partner wishes to prevent you from continuing the payout process, they can file an injunction to stop it happening. What is important is that you, Donald and Patrick hold a formal meeting (effectively a director's meeting) and record your decision. Please, PLEASE talk to you lawyer about this. There are things the limited partner could do to interfere with this but your lawyer is the best person to assess the possibilities.
