Your written arguments are generally more persuasive then your oral arguments.
Written arguments are often more persuasive than oral arguments. While courtroom performance is visible and memorable, lawyers frequently overlook the impact of well-crafted written motions. Some attorneys even avoid putting too much detail in writing to avoid tipping their hand, but that is rarely an effective strategy.
Judges often have a good sense of how they will rule before oral arguments begin. Oral arguments are typically to confirm what is already in the motions or allow attorneys to address specific questions. This is why it is important to Make Your Case Early.
This is not necessarily a bad thing. A prepared judge relies on the law and fact, so by giving it to the judge ahead of time you help prepare the judge for the hearing. This way judges don't have to figure out how to rule on a issue off the cuff while hearing the arguments for the first time.
