Quoting
latigo
Here, in contrast, the very essence of your motion admits of a fundamental disagreement as to a critical issue of fact. That issue being the authenticity and admissibility of the adverse party's proposed documentary evidence; to-wit: the invoice.
In other words your motion was a misfit. What would be fitting here would be a Motion in Limine. Meaning one seeking a preemptive adjudication by the court as to the admissibility of the invoice. If you'd like some information regarding the mechanics and purpose of such a motion from a seasoned trial lawyer, please ask me.
