The New Laws introduced several significant changes to the way the colonies were governed. They established a new system of government that included the creation of a viceroyalty, which was a higher level of administrative authority than a governorship. The laws also created a new system of land distribution that was intended to be more equitable and to protect the rights of indigenous peoples. They also sought to limit the power of the colonists and prevent them from exploiting the indigenous population.
Overall, the New Laws were a significant step in the Spanish Crown's efforts to reform its colonial administration and improve the treatment of indigenous peoples. However, the laws were not always effective in practice and were sometimes met with resistance from colonists.
