You know the fact “the content of the halachah is _” (I don’t know what the halachah says). However, you do not know “the content of the halachah is true”, because that is a falsehood. If it were costless, I would choose to know the former, but not the latter.
But you CAN’T know the latter, not on the standard theory of knowledge as “justified true belief”. You’d have belief, but probably not justified and surely not true.

That hasn’t been ‘standard’ since Gettier, I think.
Sadly, people have been trying to prop up that rotting corpse ever since. Goldman is a decent example.
