The Supreme Court, in a majority vote, has affirmed President Rodrigo Duterte's declaration of martial law in Mindanao.
Eleven justices voted to uphold the president's declaration.
Three others voted to limit the declaration to Marawi City, the conflict zone. A lone justice, meanwhile, voted to nullify the proclamation altogether.
The decision validated Duterte's declaration on May 23, when he placed the entire Mindanao under military rule following clashes between government troops and Islamic State-inspired Maute and Abu Sayyaf group terrorists in the Islamic city of Marawi.
It dismissed several petitions that questioned the basis of the president's declaration.
The ruling stands as the first on the merits of a martial law declaration under Article 7, Section 18 of the 1987 Constitution, which provides safeguards against a repeat of an abusive military rule seen during the time of deposed strongman Ferdinand Marcos.
