On August 21 we granted certification seals 017 and 018, and with them the Mexican line of our legal catalog was completed: five certified specialists covering employment, federal tax, administrative law, corporate and commercial law, and civil and family law. The catalog now holds eighteen seals across seventeen specialists in four jurisdictions (Spain, Mexico, the United States and Italy), each with a public reference number, a date and a score.
The method behind each seal is deliberately old-fashioned. Before an agent is examined, it is rebuilt from primary sources: the statutes are downloaded and read, every hard fact is verified against the official text, and anything that cannot be verified is recorded as a declared gap the agent must acknowledge rather than fill. Then the agent sits a full 13-turn examination designed around the traps of its own field. Each examination is judged by two independent tribunals, and neither may find a single blocking fault. Then the whole examination is repeated, from scratch, and judged again by two tribunals. Only two consecutive clean rounds earn the seal, and the certified version is frozen: it does not change in production without recertification.
Why two tribunals? Because single judges fail in known ways: they hallucinate faults, they retract and forget they retracted, they reward confidence over accuracy. Requiring two independent verdicts per round, with the worse verdict prevailing, converts examination from an opinion into a measurement. Scores in the Mexican cycle ranged from 8.5 to 9.4, and the transcripts behind every number are kept.
The examinations caught exactly the kind of error that makes legal AI dangerous when it goes unchecked. A corporate-law draft carried a company-income threshold that had been superseded by an official update months earlier. A mandatory corporate organ was missing from a knowledge base altogether. An absolute rule ("this procedure always requires a judge") turned out to be conditional under Mexico's new national procedure code, and was reformulated as the condition it really is. And one examination failed because a statutory quotation was truncated mid-sentence: the fix was not editing one answer but adding a permanent guardrail that strips quotation marks from any legal citation that is not an exact, byte-for-byte match of the source. Quotes, in our house, are contracts.
We publish the outcome, not just the claim: the certification cards on our legal pages carry the reference, the date, the score and the scope of every seal, and the specialists that have not yet earned one are labeled as pilots. The next examination is already underway: the Mexican consumer-law specialist entered the certification chain this week.
None of this makes an AI agent a lawyer, and it is not meant to. Every deliverable that leaves this house is validated and signed by a licensed professional. What the seals prove is narrower and, we think, more useful: that the preparation work handed to that professional has been examined, twice, by judges with no stake in passing it.
