Legal Question in Civil Litigation in California

Re: Entering new evidence during trial?

What kind of well-known facts are you talking about? The court can take judicial notice of indisputable facts (for example, the time of sunset on a particular day) but cannot do so where there is room for disagreement.

If the other side asked you for information during discovery and you didn't respond then it should have brought a motion to compel responses. If it made no such motion then you can argue that equity should bar it from hamstringing your case by doing now what it chose not to do earlier. I don't know how your judge will react to this argument and I have not researched the issue, but it may be the best argument available to you at this point.

I see that you submitted your question on Friday, even though it was only posted at about 5:25 p.m. on Monday. My response may be too late, but hopefully the case did not get as far today as you expected it do.

And as you surely realize by now, the time to ask for guidance about the introduction of evidence is long before the trial starts, not the day before it ends.
