The Palace on Tuesday said it cannot take a firm action against reports of abuse by Malaysian authorities until victims issue sworn statements.
Social Welfare and Development Secretary Dinky Soliman stressed a formal document is needed before the Philippine government can raise the issue with Malaysia.
"Yung sa ngayon, 'yung reported sa media, wala pa kaming nakukuhang tao na willing magpirma ng dokumento na ganoon nga ang nangyari (For now, we have yet to find anyone willing to sign a document attesting to the reported abuses)," reports quoted Soliman as saying.
"Hindi naman kasi tayo pwedeng magreklamo na kuwento lang po ang nakukuha (We can't file a complaint based on hearsay)," she added at a press conference in Camp Crame.

Presidential spokesperson Abigail Valte agreed in a separate press briefing at the Palace.
The Palace official, however, refused to speculate on why no one had submitted a sworn statement.
"Ayoko pong mag-speculate kung bakit kasi ayoko ring sabihin na hindi sila lumalabas (I don't want to speculate as to why, because I don't want to say that they haven't come out yet)," Valte said.
She assured the public that the Social Welfare department is "already taking steps to secure the statements of these people."
