AI Won't Fully Replace Human Document Review Anytime Soon, Expert Says
Experts say AI won't fully replace human document review soon due to practical limits.
Why it matters: Legal teams must adjust expectations about AI adoption timelines and plan hybrid human-AI workflows to maintain compliance and efficiency.
- California's Senate Bill 574, effective January 2027, bars lawyers from delegating legal practice to AI.
- The Northern District of California approved AI-assisted document review in Schulte v. LinkedIn (July 2026) but emphasizes proportionality and human oversight.
- Google's Gemini Enterprise for Legal, launched August 2026, is designed to support—not replace—legal professionals.
- Third Circuit ruled in September 2026 that using copyrighted materials to train AI is not fair use, underscoring legal limits on AI autonomy.
The legal industry is integrating artificial intelligence into document review, but fully replacing human review with AI remains unlikely in the near term. California Governor Gavin Newsom signed Senate Bill 574 on September 30, 2026, which goes into effect January 1, 2027. This law prohibits attorneys from delegating the practice of law to AI, allowing AI tools only to assist human lawyers.
Similarly, the U.S. District Court for the Northern District of California approved LinkedIn’s use of the AI-powered tool Relativity aiR for document review in the case Schulte v. LinkedIn Corp. on July 1, 2026. The court ruled this use reasonable and proportional under traditional discovery principles but reinforced the need for human oversight in reviewing electronically stored information.

In the same spirit, Google launched Gemini Enterprise for Legal in August 2026. Google General Counsel Halimah DeLaine Prado emphasized that AI tools are intended to support, not replace the judgment of lawyers and judges, highlighting the ongoing necessity of human expertise.
Furthermore, the September 29, 2026 decision by the Third Circuit Court of Appeals emphasized legal constraints on AI training data usage. The court ruled that the use of Westlaw’s copyrighted headnotes to train AI was commercial and not fair use, affirming Thomson Reuters’ rights in a case against ROSS Intelligence. Read more.
These developments show a legal landscape balancing AI's efficiency benefits with ethical and legal limits. Legal teams should prepare to combine AI efficiency with necessary human judgment rather than expect total automation anytime soon.
By the numbers:
- January 1, 2027 — Effective date of California's AI legal use regulations (SB 574)
- July 1, 2026 — Court approval for AI-assisted document review in Schulte v. LinkedIn
- August 2026 — Launch of Google's Gemini Enterprise for Legal
Yes, but: While AI tools improve efficiency, regulatory and ethical frameworks emphasize ongoing human responsibility, limiting AI's autonomous legal practice.
What's next: Legal teams should monitor evolving state regulations and court rulings shaping AI's role in legal workflows through 2027 and beyond.
