The latest news on California's long-running de facto moratorium on executions is that there will be no executions in California until 2013. The earliest that criminal justice legal challenges to California's lethal injection procedures will be concluded is September 2012. Because of this delay, it is unlikely that any execution could proceed before 2013.
The legal challenges began in 2006 by Michael Morales, a convicted murderer on death row. Morales claimed that California's lethal injection method is cruel and unusual punishment and is thus unconstitutional. Morales argued that the lethal execution method in use made it more likely that an inmate would die an agonizing death while unconscious. Morales was granted a reprieve by former San Jose U.S. District Judge Jeremy Fogel.
Judge Fogel later concluded that the lethal injection procedures in California were potentially unconstitutional and that the state was to change them. Following this decision, the State of California changed its lethal injection methods and built a new execution chamber at San Quentin.
