Stories, watch the law move

real histories from the Luxembourg corpus and the ten EU acts, computed live

Point-in-time retrieval sounds abstract until you watch a law move. These are real histories held by Lex, every number below is computed from the signed indexes as this page renders, and every link lands on the evidence.

The law that could not sit still

Luxembourg's Covid-19 measures act. Rules on gatherings, masks and closures were rewritten again and again, which is exactly when "what did the rule say that week?" stops being an academic question.

Banking rules in waves

The Capital Requirements Regulation, the rulebook a Luxembourg bank must apply. Its own Article 92 (the capital ratios) has more than one lifetime.

The criminal code is a moving target

The honest half. A demo that only shows wins is a brochure. Ask for a law in 1900 and Lex refuses, with a reason code, instead of inventing a plausible text , here is exactly what it holds and what it lacks.
