The Emperor Charles V established this dignity in 1536, when he was informed about the miserable condition of the Sicilian business on the subjects of Justice and Patrimony, and established to send a Minister who had to help the Viceroy in governing the Kingdom and who regulated the provisions with his advice.

He had to be foreign, because he could be impartial, as all the other ministers, members in the Holy Council were nationalist and country people for an old privilege of the Kingdom of Sicily.

However, in spite of the law, Doctor Nicolosi was nominated Consulter for his extraordinary legal merits and for his impartiality. He was born in 1726 and died on 3 August 1815.

(1) The King sent a Minister every 25 years to look after the condition of the public affairs; he exercised the power to recognise the Royal Purposes, he checked the administration of justice in the Royal Councils, he heard the charges, he determined the proceedings, and convicted the guilty persons. At the end of his visits he left the determinations done and they had to be strictly observed by the judges.
