Luis Carrillo was, from November 1567 to about July 1568, royal commissioner with Alonso Muñoz for the inspection of the viceregal government of New Spain for King Philip II.
Upon his arrival, Viceroy Peralta reviewed the cases and suspended the death sentences against the sons of Cortés.
The Council proposed to the king that he send a special commission to the colony to investigate the situation and bring actions against guilty parties, up to and including the removal of the viceroy.
The first decision of the commission was to construct a jail, "in the manner of those of the Santo Officio [Inquisition]", to imprison the principle accused, including Baltasar de Aguilar Cervantes and Luis Cortés.
Muñoz and Carrillo continued to jail innocent people until Spain, acting on petitions from the colonists, ordered their recall.
Muñoz remained in Mexico City in accordance with his instructions from the king, to continue as interim governor of the colony until the arrival of a new viceroy.
When Carrillo arrived in the port of Veracruz, he found the deposed viceroy waiting to embark for Spain.
Both commissioners were ordered to return to Spain immediately and the government of the colony was left in charge of the Audiencia.
Muñoz, the only survivor of the three commissioners, gave the formal report of the mission to the king in late August, 1568.
