The party that is asking for summary judgement must feel that they have a pretty air-tight case. Generally, summary judgement is requested when the party requesting it can show the judge that there is no merit what-so-ever to the other party's case.
In this one, it would appear that they feel that there is no merit to Paxton/ Worthington's argument. Summary judgement is generally granted when no factual info has been presented so there is really nothing for a judge or jury to decide.
I wonder if Paxton/Worthington will counter with their own request for summary judgement? It wouldn't be an unusual counter move but they should do it quickly if they feel they actually have a case.
Thanks for the digging, the plot continues to thicken, doesn't it.
