Deposing opposing counsel
I am a plaintiff in pro per. I have discovered that the opposing counsel has knowledge of relevant facts for my case. These facts are crucial to preparation of my case.
Also, I can not obtain the relevant information from other means.
1) Do I need court permission to depose the opposing counsel?
2) If yes, what form do I use for this?
3) Based on my discovery that the opposing counsel tried to negatively influence a contractor to change his report in the favor of the defendant, is this action considered as mal-practice on the part of the opposing counsel?
4) If yes, should I address this in my current lawsuit in the superior court, or this will be a new lawsuit against the opposing counsel?
I greatly appreciate clarification and your time.
