I don't think the law exists to arrive at the truth. If it did, we wouldn't have exclusionary rules, we wouldn't have presumptions of innocence, we wouldn't have proof beyond reasonable doubt.

Every lawsuit results from somebody doing something wrong. If everybody did right, we wouldn't need laws.

The law is agnostic about truth. It's very skeptical of ultimate truth. That's why freedom of speech permits lies to be told.
