From the article it sounds like they banned any kind of statistical analysis. I can understand that you might want to put a temporary ban on AI's that directly advise judges, however this seems excessive.
This is not what the law says. In France, judgements are anonymized before being published, however the name of the judges and their teams are kept.
The law says that the names of the judges cannot be used to predict or analyse decisions from a specific judge/court.
Although I can understand why it would be appealing to do so (eg to prove bias...), it could easily be misused to put judges under political pressure, or encourage court shopping by less ethical entities.
Also this seems in line with data privacy laws, where you must get prior consent in order to use personally identifiable data.
It has nothing to do with analysis of legal decisions in general.
