Obviously this (along with the original unwritten order a few weeks ago) is causing a stir, but this decision isn't as weird as it sounds. The defendant's assertion was essentially a retroactive application of privilege: he didn't use Claude to draft documents at his attorney's request but instead used Claude effectively in lieu of an attorney and later provided the Claude-drafted materials to his attorney (heavily paraphrasing here). Privilege is not a bandage that closes self-inflicted wounds.

I have some concerns about some of the reasoning, namely the practical implications of referencing Claude's TOS in a world where public AI features are creeping into everything, but I expect some of the reasoning is based on this particular defendant likely being more sophisticated than an average person.
