The International Criminal Court (ICC) Registry said former Philippine President Rodrigo Duterte has experienced “rare” falls inside his detention facility, but confirmed that no such incidents have been recorded in the past 30 days.

In a seven-page filing dated May 13 and made public Thursday, the Registry said adjustments have been made within Duterte’s cell and visiting areas to improve his safety and mobility.

“Ergonomic adjustments are made to the placement of items in his cell and in the visiting rooms in order to allow him to have more free and stable movement,” the Registry said. “On rare occasions where Mr. Duterte did have a fall, ICC Detention Centre custody staff were able to respond immediately to assist him and promptly call for a medical assessment.”

The Registry added that further modifications were introduced following those incidents to better support his comfort and movement.

The filing was submitted in response to a request from Duterte’s defense team seeking information about his condition while in detention.

In an earlier submission, former lead defense counsel Nicholas Kaufman said Duterte had reported “frequent episodes of falls occasioned by a loss of balance” to his legal team and immediate family, and requested access to surveillance footage from his cell.

The Registry said Duterte is under continuous cell monitoring for health and safety reasons, based on medical advice describing him as “an elderly detained person, with increased fall risk due to age and several chronic physical ailments.” It did not disclose specific medical details, citing the confidentiality of his medical records.

According to the filing, the monitoring allows custody staff to observe Duterte around the clock, respond quickly to any incidents, and coordinate closely with medical personnel to optimize his care.

“The use of cell monitoring helps to optimize his care, which is why it continues to be reviewed and may be ordered every 14 days until the Medical Officer no longer deems it necessary,” the Registry said.

It added that Duterte’s movements are “consistent with his age and mobility,” and that any adjustments to his detention conditions are based on medical advice and internal assessments, similar to other operational considerations such as hearing schedules and seating arrangements.

The Registry also noted that Duterte and his legal team have access to his medical records, and that his care remains under constant supervision at the ICC detention center.
