And it was presented to the public at large as such by the defendant.

Yes, and even though it's not authenticated, it did support the first plaintiff's argument.

The first plaintiff simply says that since Obama's father was not a US citizen at the time of Obama's birth, he can't be a natural born citizen.

The attorney entered the digital copy of the BC as a evidence from Obama (or at least a representative of Obama) that his father was not a US citizen. He also quoted Obama's book, in which he tells a story about his father that would exclude him from being a US citizen.

This is really little more than introducing testimony from Obama as evidence. It doesn't actually determine whether it's true or not.
