Can it be judicial misconduct to not rebut arguments of losing party?

Question

Bob sues Rob in a civil court (adversarial system).

Bob contends:

I am right and Rob is wrong because of A.

Rob defends:

No, A does not apply because of X.

Bob replies:

No way. X does not stand because of B. Therefore, A still applies.

The judge says:

I accept Rob's contention that A does not apply because of X. Bob has no case.

That said, the judge does not rebut or even talk about Bob's B (which negates Rob's X in Bob's view). It is known that Bob's reply was admitted and the judge definitely has seen it — it is not the case that it was dismissed for procedural reasons like late filing or whatever.

Where rights of appeal are not available for whatever reason (procedure-specific statutory prohibition, or the court already being the top court), are there any other remedies for Bob e.g. a claim of judicial misconduct?

Answer 1

A judge does not have to address every argument raised in their judgement

Otherwise every judgement would be absurdly long.

All the judgement needs to demonstrate is that the judge turned their mind to the arguments. The judge accepted X - implicit in this is the rejection of B. The judge has considered A and X and stated their reasons why they like X over A - it’s an appeal proof judgement on that point.
