Bob has a point. You have a valid question. On one level, I beleive that TS will have to have his own representation, whether himself (pro se) or his own attorney.
As I see it, 3-ABN has two major forms of defending itself, along with what I would call minor ones:
1) TS did not do it, therefore, we have no liability.
2) If TS did it, we are not responsible, therefore, we have no liability.
As to minor issues, tlhey would include such things as legal issues such as the Stature of Limitations.
If 3-ABN were to plead # 1 above, it would clearly be in its interests as it would release it from liability if successful and it would clear TS.
Litigation is is some sense a "throw of the dice." One can never predict with 100% certainty what the decision will be. Even when a win is claimed to be certain, it may only be a partial win.
E.G. I am knowledgeable of a loan company that won a judgement against an elderly man and the judge ordered the payment to be $5.00 a month. The interest on the loan alone was more than $5.00 a month. Therefore, at the time of the man's death, the debt to the loan company was more than it was at the time of the litigation. And the loan company had the costs of the litigation. NOTE: The judge found that under the law the man owed the debt, but he found bad faith on the part of the loan company and he ruled that due to the income of the man the obligation to pay was limited to $5.00 a month.
I am aquainted with another case where both the plaintiff and the defendent got a partial win. But, the judge ordered the defendent to pay the plaintiff's legal expenses in the amount of $72,000!
Anyway, I believe that TS will have to have someone to officially represent him. How will this unfold? We shall simply have to wait and see.
