California lawmakers vote to expand ban on death penalty for the intellectually disabled

More people convicted of murder may receive death penalty exemptions under a measure California lawmakers approved Friday that would expand whom the courts can classify as intellectually disabled.

Under the legislation, the death penalty could not be sought against defendants if health experts determined there was evidence of an intellectual disability that began during their “developmental period” — the time in a person’s life when their brain is developing — as defined by mental health diagnosis standards.

Current California law prohibits intellectually disabled defendants from being sentenced to death if mental health experts determine that their impairment was evident before they were 18 years old. This legislation removes that age threshold.

“All we’re really doing is updating the state of the science used to determine intellectual disabilities and developmental disabilities to what is currently being used,” said Assemblyman Mark Stone (D-Scotts Valley), who introduced the bill. “There are people who are sitting on death row who shouldn’t be there and don’t need to be there. That’s what we’re trying to rectify.”

The bill would also prohibit prosecutors in capital cases from adjusting the results of tests measuring a defendant’s intellectual ability based on their race, ethnicity, national origin or socioeconomic status.

The bill received strong support from death penalty opponents and was contested by the California District Attorneys Assn., which criticized the measure for creating “a vague and prejudicial loophole that would result in a miscarriage of justice for all murder victims and their loved ones.”

Assembly Bill 2512 will head to Gov. Gavin Newsom for his consideration. A staunch opponent to capital punishment, the Democratic governor just months after taking office placed a moratorium on the death penalty in California and ordered the dismantling of the execution chamber at San Quentin State Prison. The moratorium will expire as soon as Newsom leaves office, pushing decisions on capital punishment to his successor.

“The death penalty still technically exists,” Stone said. “So this policy is still very relevant and necessary.”

If the bill is signed into law, inmates on death row would have the right to petition the courts to assess whether they qualify as intellectually disabled under the new definition.

Retired Alameda County prosecutor Angela Backers, who handled death penalty cases for decades, said reputable mental health experts overwhelmingly agree that intellectual disabilities become evident before people turn 18 years old. Replacing the age threshold with a defendant’s age-indeterminate “developmental period” would allow defense attorneys to argue that their clients are intellectually disabled even if no signs of impairment surfaced until they were in their 30s, she said.

“They don’t want there to be a definition of intellectual disability. They want it to be all wishy-washy,” said Backers, co-chair of the California District Attorneys Assn. capital litigation committee. “All qualified experts agree that if you have an intellectual disability, it manifests itself before 18.”

In 2002, the U.S. Supreme Court ruled that it was cruel and unusual punishment to impose a death sentence on a person convicted of murder who had a mental disability.

In that ruling, Atkins vs. Virginia, the court relied on a definition of intellectual disability set by the American Psychiatric Assn., which said that the onset of such disabilities occurred before the age of 18.

California later adopted the Supreme Court’s definition for capital cases in state law, which stated that intellectual disability means “condition of significantly subaverage general intellectual functioning existing concurrently with deficits in adaptive behavior and manifested before 18 years of age,” when the brain is still developing.

The American Psychiatric Assn. has since changed its definition of intellectual disability, removing the age threshold and determining that the “developmental period” of a person should be left up to the discretion of physicians.

Stone said existing California law should be changed to reflect that new definition.

The assemblyman’s bill also prohibits prosecutors from arguing that Black and Latino people have less access than white people to adequate education, healthcare, nutrition and other essentials while growing up, and therefore may score lower on tests measuring potential intellectual disabilities, leading to a determination that results should be adjusted upward.

Backers, however, said that addresses a problem that does not exist.

“Where’s the proof of that? Where is the proof where prosecutors inflate the IQs of people of color,” she said.

USA | Should Medical Research Regulations and Informed Consent Principles Apply to States’ Use of Experimental Execution Methods?

New drugs and med­ical treat­ments under­go rig­or­ous test­ing to ensure they are safe and effec­tive for pub­lic use. Under fed­er­al and state reg­u­la­tions, this test­ing typ­i­cal­ly involves clin­i­cal tri­als with human sub­jects, who face sig­nif­i­cant health and safe­ty risks as the first peo­ple exposed to exper­i­men­tal treat­ments. That is why the law requires them to be ful­ly informed of the poten­tial effects and give their vol­un­tary con­sent to par­tic­i­pate in trials. Yet these reg­u­la­tions have not been fol­lowed when states seek to use nov­el and untest­ed exe­cu­tion meth­ods — sub­ject­ing pris­on­ers to poten­tial­ly tor­tur­ous and uncon­sti­tu­tion­al­ly painful deaths. Some experts and advo­cates argue that states must be bound by the eth­i­cal and human rights prin­ci­ples of bio­med­ical research before using these meth­ods on prisoners.

Georgia parole board suspends scheduled execution of Cobb County death row prisoner

The execution of a Georgia man scheduled for Wednesday has been suspended as the State Board of Pardons and Paroles considers a clemency application.  Stacey Humphreys, 52, would have been the state's first execution in 2025. As of December 16, 2025, Georgia has carried out zero executions in 2025. The state last executed an inmate in January 2020, followed by a pause due to COVID-19. Executions resumed in 2024, but none have occurred this year until now. Humphreys had been sentenced to death for the 2003 killings of 33-year-old Cyndi Williams and 21-year-old Lori Brown, who were fatally shot at the real estate office where they worked.

Oklahoma board recommends clemency for inmate set to be executed next week

A voting board in Oklahoma decided Wednesday to recommend clemency for Tremane Wood, a death row inmate who is scheduled to receive a lethal injection next week at the state penitentiary in McAlester.  Wood, 46, faces execution for his conviction in the 2001 murder of Ronnie Wipf, a migrant farmworker, at an Oklahoma City hotel on New Year's Eve, court records show. The recommendation was decided in a 3-2 vote by the Oklahoma Pardon and Parole Board, consisting of five members appointed by either the governor or the state's top judicial official, according to CBS News affiliate KWTV. Oklahoma Gov. Kevin Sitt will consider the recommendation as he weighs whether to grant or deny Wood's clemency request, which would mean sparing him from execution and reducing his sentence to life in prison without the possibility of parole.
