IGAS is the Inspectorate-General for Health Activities (Inspeção-Geral das Atividades em Saúde or IGAS), the government body that inspects and audits public and private health services, investigates complaints and can recommend sanctions or changes. After reported failures in emergency care, IGAS can open inquiries, publish findings and advise the Ministry or the SNS on corrective measures; residents and patients can also file complaints that IGAS may investigate.

The PJ (Polícia Judiciária) is Portugal's national criminal investigation police agency, founded in 1945. Operating under the Ministry of Justice and supervised by the Public Ministry (prosecutors), the PJ is a "higher criminal police body" specializing in serious and complex crimes. ​ Mission: The PJ assists judicial and prosecuting authorities by investigating terrorism, organized crime, homicide, kidnapping, drug trafficking, corruption, cybercrime, financial crime, and money laundering. It conducts forensic examinations, operates Portugal's Interpol and Europol liaison offices, and maintains specialized units including the National Counterterrorism Unit and National Anti-Corruption Unit. ​ Difference from PSP/GNR: While PSP (civilian urban police) and GNR (military rural police) focus on preventive policing, public order, and investigating minor crimes, the PJ exclusively handles serious crime investigation requiring specialized technical and scientific expertise. PSP and GNR report to the Ministry of Internal Affairs; PJ reports to the Ministry of Justice. PJ officers receive higher pay and prestige but face greater operational risk.

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.

Qualified fraud (burla qualificada) is a more serious form of fraud under Portuguese law that involves aggravating factors like organized schemes, use of false documents or causing large financial losses. It carries heavier criminal penalties than simple fraud and is usually investigated by the Polícia Judiciária; victims can pursue criminal charges and civil compensation.
