From that article:
ORLANDO, Fla. -- An attorney for Casey Anthony's parents has filed a motion to prevent them from giving depositions in the Zenaida Gonzalez civil suit.
The lawyer for George and Cindy Anthony said in the motion Tuesday that forcing them to give depositions in the suit is nothing more than an attempt to annoy and embarrass them.

I agree with this. Casey is the defendant in this suit, not the A's. Casey is the one who gave ZG's name to LE. There is nothing the A's can say that will help either side. If they say Casey has mentioned the name in the past, it doesn't prove that she was talking about this particular ZG or that she didn't make the whole thing up. If they say they never met ZG, what does that prove? Certainly not that this is the ZG Casey accused. I believe this is nothing but harassment of the A's and it's totally unnecessary.
