Summary

BAILII has deployed an anti-bot system named Anubis using Proof-of-Work (Hashcash-style) to block AI company scraping of its European Court of Justice case database. The system adds computational load for mass scrapers while remaining negligible for individual legitimate users. Access requires modern JavaScript; plugins like JShelter must be disabled.

What changed

The access page is a technical anti-bot barrier, not a regulatory document. Legal researchers and automated compliance monitoring systems attempting to retrieve EU European Court of Justice case C44023 will encounter a Proof-of-Work verification challenge requiring JavaScript execution. Organizations using browser security extensions may need to configure domain-specific exceptions.

Compliance teams relying on automated case monitoring or legal database APIs should note that standard headless browser approaches will trigger the Proof-of-Work challenge. Alternative access methods or legitimate-user browser sessions will be required to retrieve the underlying case content.

You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites. This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.

Anubis is a compromise. Anubis uses a Proof-of-Work scheme in the vein of Hashcash, a proposed proof-of-work scheme for reducing email spam. The idea is that at individual scales the additional load is ignorable, but at mass scraper levels it adds up and makes scraping much more expensive.

Ultimately, this is a placeholder solution so that more time can be spent on fingerprinting and identifying headless browsers (EG: via how they do font rendering) so that the challenge proof of work page doesn't need to be presented to users that are much more likely to be legitimate.

Please note that Anubis requires the use of modern JavaScript features that plugins like JShelter will disable. Please disable JShelter or other such plugins for this domain.
