The initial duties of the procurator-general included checking that the Senate decisions comply with the laws in force, as well as overseeing decency during meetings.
In March 1730, after the abolition of the Supreme Privy Council by Empress Anna Ioannovna, the Senate was restored to its authority, and in October it was deemed necessary to reinstate the position of prosecutor general; however, a year later, after the establishment of a new central authority – the Cabinet (consisting of three cabinet ministers) – the influence of the Senate fell again; no appointment has occurred.
In the interregnum from the death of Anna Ioannovna to the accession of Elizabeth Petrovna, the role of the Senate began to increase; the post of Prosecutor General was reinstated; Prince Nikita Trubetskoy was appointed to it.
In 1762, Catherine the Great significantly reformed the Senate on her accession to the throne; Prince Alexander Vyazemsky was appointed to the post of Prosecutor General.
With the reform of public administration undertaken by Alexander I, since 1802, the position of the head of the Senate was combined with the position of minister of justice and acquired his final terms of reference: the prosecutor general was the head of the prosecutor's office and the office of the Senate and also enjoyed the right to supervise the activities of officials of the entire judicial department.
