PHYSIX OBSERVATION

Courts are shifting from asking "was AI used" to "was the content verified," and signing equals accountability has become the consensus. For lawyers, AI is not off-limits, but unverified submissions directly threaten their license to practice. This trend will force legal AI tools to strengthen citation traceability and also expose self-represented litigants to more hidden technical barriers.
