But they don't investigate, so not likely to be bothered by any howls either. IMO

The superior body of the Public Prosecution Service is the Procuradoria-Geral da República (attorney-general's office), presided by the Procurador-Geral da República (PGR).
The PGR is the only magistrate of the Public Prosecution Service that is politically designated, being proposed by the Government and appointed by the President of the Republic for six years in office. The PGR is also the only magistrate of the Public Prosecution Service that can be chosen from among persons that previously were not magistrates, the person chosen not even being mandatory linked to any area of recruitment or having a specific training. However, in practice, most of the persons appointed for the office of PGR came from the career magistracy.
Under the Procuradoria-Geral da Reública there are also four procuradorias-gerais distritais (district attorneys-general's offices) and 23 procuradorias da República (attorney's offices). The first ones represent the Public Prosecution Service in the courts of second instance and the last ones in the courts of first instance.
For the role of directing the criminal investigation, each of the Public Prosecution Service offices includes a department of investigation and prosecution, composed of attorneys specially dedicated to the investigation of the most serious crimes. For the criminal investigation, the Public Prosecution Service also controls the activity of the Judiciary Police.

My interpretation of this is the AG can control, by delegation, what the PJ investigate.
