The Oklahoma Pardon and Parole Board has recommended the commutation of 527 inmates. 

This is the largest commutation in history. Governor Kevin Stitt signed off on the recommendation Friday, November 1. 

According to the board, an inmate's release would immediate if they already served one year.

The rate of Oklahoma's incarceration will drop more than 1.7%, and the state is projected to save about $12 million dollars.
