""Información en Derecho"" is the lengthiest piece of writing from Vasco de Quiroga's hand that we have knowledge about; it is dated México July 1535. It was partly a response to the Crown's reversal of a previous prohibition of the enslavement of the native population. It contains a detailed analysis of the legal and ethical issues concerning slavery in the Americas and includes a recommendation of a new policy towards the Indians based on the model laid out in Thomas More's Utopia.
