Yeah, “scandalous” is too much. I can see “impertinent”, though. I don’t agree, but courts are notoriously uptight.

impertinent

I don't know if there's a specific legal meaning

legal jargon isn't always plain English

but it might be that the meaning there is the other English meaning of "impertinent":

https://en.wiktionary.org/wiki/impertinent

impertinent (comparative more impertinent, superlative most impertinent)

1. Insolent, ill-mannered or disrespectful; Disregardful.

2. (archaic) Not pertaining or related to (something or someone); Irrelevant or useless.

I mean, the term right before it in the code is "immaterial", which is very close to the second common-language definition. Just because it's archaic in common-language use doesn't mean that it is in the legal world

a lot of legal terms with jargon meanings were in common use at one point.

Yeah, sounds like it:

Definition: Impertinent means something that is not relevant or important to the matter at hand. For example, if someone is talking about their favorite food and you start talking about your favorite color, that would be impertinent because it has nothing to do with the topic being discussed. In legal terms, impertinent evidence or allegations are ones that do not help prove or disprove the case and are not important for the court to consider.
