The Philippine National Police (PNP) will arrest former First Lady and Ilocos Norte Rep. Imelda Marcos once the court issues an arrest warrant.
Marcos was sentenced to imprisonment for a minimum of six years to 11 years and a month maximum. Aside from this decision, she is no longer allowed to hold any position in public office.
Ferdinand Marcos, who along with his cronies was accused of pilfering $10 billion from the Philippines, fled with his family to the U.S. after a people's uprising ended his 20-year rule in 1986.
However, neither Imelda nor any of her lawyers were present during the promulgation of the decision. She was charged for making seven bank transfers totalling $200 million to Swiss foundations during her term as Manila governor.
Imelda Marcos returned to the Philippines in 1991, during the administration of Corazon Aquino, to face more than 100 criminal and civil cases on charges that she and her husband siphoned off $5 billion-to-$10 billion and committed human rights violations during the 20-year dictatorship.
Marcos, 89, famous for a huge collection of shoes, jewellery and artwork, is facing dozens of protracted graft cases that have hounded her since her family was toppled in an army-backed popular uprising in 1986. Her congressional term will end next year but she has registered to run to replace her daughter as governor of northern Ilocos Norte province.
Rosales said the decision was a huge setback to efforts by the Marcos family to revise history by denying numerous atrocities under the dictatorship, and urged Filipinos to fight all threats against democracy and civil liberties.
The latest graft conviction of former First Lady Imelda Marcos highlighted "a working and impartial justice system" in the country, Malacañang said Friday.
This is not the first time that the former first lady has faced corruption charges.
The court's decision came 27 years after the case was first filed. The former commissioner of the Presidential Commission on Good Government said the verdict could be reversed by a Supreme Court that is mostly composed of judges appointed by the Philippines' "Marcos-idolising" President Rodrigo Duterte.
"The Executive Branch is not in the business of exerting undue interference or influence in the affairs of another separate and independent branch of the government", Palace spokesman Salvador Panelo said in a statement.
"While we note that there are still legal remedies available to Congresswoman Marcos, this latest development underscores that our country now has a working and impartial justice system that favors no one", Panelo said in a statement.
