Why this matter warrants attention
The Supreme Court of New South Wales dismissed the applicants' summons for leave to appeal and issued a warning regarding the use of AI-generated content in legal submissions. The Court identified that the applicants cited a non-existent High Court authority, which it characterized as a matter of grave concern and contrary to established practice notes.
The Court reasoned that the citation provided by the applicants did not correspond to any High Court authority and instead directed to an unrelated case. It stated that the use of AI in such a manner is contrary to Practice Note SC Gen 23 and constitutes a matter of grave concern.
Australian courts are now warning counsel for unverified citations; document every authority check before filing.
