There are "facts" and facts. The undisputed facts are those where both parties "stipulate" - neither party intends to adduce evidence that the claim is false. Juries aren't at liberty to make up their own minds about facts that haven't been disputed.
It's the disputed "facts" that juries weigh - that is, the evidence and testimony.
> Lawyers instruct juries on the law
That's rather slippery; I think that technically, the lawyers are "servants of the court", so they really instruct the court on the law. And "the court" means the judge. The judge then instructs the jury on the law.
But in fact, these lawyers are advocates; their business is to expose those parts of the law and the evidence that are advantageous to their client, and damaging to their adversary. It's not reasonable to assume that the judge is unbiased (any more than the advocates).
