The Public Prosecution Service (Procuradoria-Geral da República or PGR) has prohibited magistrates from using artificial intelligence to predict the probability of conviction or the risk of recidivism among defendants. The new rule mandates that AI tools may only serve as auxiliary instruments and cannot be used to generate automated profiles for suggesting coercive measures.

Context & Explainers
The Ministério Público (Public Prosecution Service) is Portugal's independent state prosecution body, responsible for leading criminal investigations, bringing charges, and representing the public interest in court.
The MP operates autonomously from the government and the police, though it directs criminal investigations carried out by the Polícia Judiciária, PSP, and GNR. It is led by the Procurador-Geral da República (Attorney General), who is appointed by the President on the government's proposal.
The MP gets involved in high-profile cases including corruption, financial crime, and incidents of potential institutional negligence. It also defends the legality of government actions and protects citizens' fundamental rights through the courts.
