Opposing counsel doesn't seem to understand summary judgement or material facts

The opposing lawyer in a case filed a summary judgment for dismissal, in my state a requirement for summary judgement is accepting the material facts of the case as presented by my side. Then, in both the written and verbal argument, the opposing counsel invented facts which were completely opposite to the [now undisputed] facts of the case, and based his entire argument on these fake facts. My side stated this both in writing and verbally, but the judge outright dismissed the case without allowing discovery, and declined to provide any legal explanation for the dismissal. The case in now in appeals, but I'm wondering if willful ignorance of the law , or willful misrepresentation of facts by a licensed attorney is worthy of filing a complaint (or sanctions) over. If not, how far does it have to go to be something generally not acceptable? If the opposing attorney claims ignorance of the law in his appeal brief, is that enough? Where would/should be the line be?
