Arguably shouldn't judges follow their judgement on the cases they work on ? Throwing out baseless cases happen every day, a company abusing the system having their ridiculous complaints thrown out would be reasonable.
To me that is the basic reason for having humans in the process.
I think the point was the case should not be thrown out because the judge doesn't like the plaintiff but only if the case is baseless. You can't judge the validity of a case just because preconceived notions about the plaintiff.
Wether a case is deemed baseless is not cold and dry facts, there is a judgement of merit and intention of the filing side.
Also taking into account the surroundings of a case, including who’s involved and their history is not preconception (or then everything becomes preconception).
It’s not the same if you’re a CEO filing a suit against a grandma who shouted insanities at you when you fired their son, and if you’re a worker subject to verbal abuse from your boss.
To me that is the basic reason for having humans in the process.
