GP:

I do not know where to look for the transcript. Maybe Todd can help. As I understand it the original suit was brought by a consortium of environment groups and tribes. They won, which essentially forced the BPA and Corps of Engineers to abandon their plan to reduce spill by 39%

Then the BPA and Corps appealed the decision and lost the appeal.

I would guess that in the original case the defendants were BPA and the Corps.

Here is a link to several newspaper articles on the case.
