A ruling by the Pennsylvania Supreme Court on Tuesday will give oversight to the state's Office of Attorney General when Philadelphia District Attorney Larry Krasner seeks to overturn cases. 

The ruling was a victory for the family members of a man murdered in 2004. Lavar Brown was found guilty of the murder of Michael Richardson in 2004, and he was found guilty of the murder of Robert Crawford in 2005. 

Brown sought relief under Pennsylvania's Post Conviction Relief Act (PCRA). While his first attempt was denied, Krasner's office granted Brown a new trial on his second attempt. 

The family members of the victims asked the state Supreme Court to intervene and review Krasner's order. Tuesday's ruling reverses that order, WPVI reported. 

"The Court held that the DAO's concession was not reliable, as it had failed to disclose material evidence, submitted a false stipulation, misrepresented facts, and opposed a required evidentiary hearing," Pennsylvania Attorney General Dave Sunday said in a statement. 

The court also ruled that the attorney general's office will have oversight when the Philadelphia district attorney's office tries to overturn a conviction, saying that the office had made "unreliable concessions unsupported by the facts and law."
