Too bad dvt deleted their comment calling your comment a low effort and negative, because your point is valid.

Unless OP is using hosted models, especially those with always-on training, that's quite clear cut breaking at least privacy laws, likely more, especially if the court documents are additionally protected.

So that's basically showing the HN how egregiously a number of lawyers, accountants and paralegals "conspire" to break the law in order to process more cases in parallel and earn more money.

I think that's pretty accurate?

If OPs father doesn't want to do it manually they must at least run it locally, or obtain the court permission to share the privileged information with a number of third parties, possibly shoving it into the future corpus of information.
