Either this is fake, or they had a law firm seriously trying to steamroll them with no regard for the consequences. Motions for summary judgment are supposed to served to the opposing party, usually weeks in advance of any court date to allow for a response time. Upon learning this a judge should just deny the motion on those grounds, maybe do something to the law firm for trying to pull one over on him. A complaint to the state bar for this might result in sanction for the firm.
I would guess this probably happens a lot more than you may realize.
