I mean, not really. This is weird shit to put in a legal document and is pretty pointless. It’s also just hard to read due to contrast issues (which can be particularly relevant depending on any disabilities of interested parties, etc.). Like I’m pretty sure there is text on there that does not meet WCAG guidelines.

It’s definitely not appropriate for a court document. I’d go farther and say putting anything to dramatically draw attention to oneself in a court document is inappropriate. That’s simply not what court documents are for. They should strive to be as mundane, uninteresting, an impartial as possible.
