Reelectionist Senator Ronald "Bato" dela Rosa says he is hoping that the Supreme Court (SC) will make a fair ruling on the petition they filed to challenge the legality of former president Rodrigo Duterte's arrest warrant from the International Criminal Court (ICC).

Dela Rosa hoped that the High Court would not be swayed by politics “because we know we are co-equal branch of government".

"Sana buo ‘yung kanilang pasya, walang konsiderasyon na politikal o pressure (I hope that they're sure of their decision and not considering any politics or pressure) from other co-equal branch of government, not even from the Senate, na (that) one of its members is one of the petitioners,” he said in a recent interview.

“Mas lalo na sana, not even the Malacañang na alam natin kung gaano na sila ka-kwan ‘no, ka-oppressive sa kanilang mga pinaggagawa (I also hope that not even Malacañang would exert pressure because we know how oppressive they are)," he added.

Duterte and Dela Rosa, through their legal counsel Israelito Torreon, filed a petition for certiorari against Executive Secretary Lucas Bersamin, Justice Secretary Boying Remulla, et al regarding the supposed actions taken against them by the Marcos administration.

One of the petition's prayer is the grant of Temporary Restraining Order (TRO) against Duterte's arrest, which was later denied by the SC.

They then filed a motion urging the SC to exhaust all efforts to bring Duterte back to the Philippines.

The former chief of the Philippine National Police (PNP) said that he plans to exhaust all legal avenues and remedies available to defend himself.

But he also says that he is ready to face arrest should the courts and the Senate choose to give him up.

"If all legal remedies are exhausted and still justice is to no avail, then I don’t want my family to suffer from cops looking for a heartbeat. I am ready to join the old man hoping that they would allow me to take care of him," Dela Rosa posted on Facebook following Duterte's arrest.
