Malacañang on Wednesday said there is no basis to require President Ferdinand Marcos Jr. to undergo a drug test, citing existing Supreme Court jurisprudence.
Palace press officer Claire Castro said the request stemmed from unproven claims and should not compel the president to submit to medical examination.
She said previous rulings of the high court established that a sitting president cannot be forced to disclose medical records without sufficient grounds.
Castro noted that a similar petition involving a former president had been dismissed due to lack of evidence supporting claims about health concerns.
The statement came after a group filed a petition seeking to compel Marcos to undergo a hair follicle drug test and disclose his health condition.
The petitioners invoked provisions of the Constitution requiring transparency in cases of serious illness affecting the president.
Malacañang, however, maintained that such provisions do not apply in the absence of verified information or credible evidence.
Officials said the government expects the SC to uphold established legal principles when resolving the petition.
