Both the plaintiff and the respondent has to provide each other with an evidence list that will be used to prosecute and defend against. As I understand it, this has been done in this particular matter. Then there are pre-trial motions. Everthing for stating arguement against allowing certain evidence in to arguing why the case should move forward to the limiting of the number of questions that can be asked on a specific piece of evidence to arguing against the way certain questions can be asked. This is a long, arduous process.
Motions can also be rather wordy.
And at the end of the day each side should have a transcript of the record so that they can tighten up their arguements. You must purchase the trial transcripts by the page. Now that might not sound like a lot, but understand that each line is double spaced, and it is numbered usually 1-30, so there are 30 lines indented to approximately two inches on each page. The daily trial transcript can add up to hundreds of dollars. The CIA and Department of Justice use tax dollars to supply them with trial transcripts.
