If anything, it may embolden the ICC to take a tougher stance and move ahead with prosecution of specific officials.
He accused United Nationsspecial rapporteurs and ICC investigators of painting him as a "ruthless and heartless violator of human rights who allegedly caused thousands of extrajudicial killings".
Under the statute, the ICC can only investigate and prosecute the crimes in situations where states are "unable" or "unwilling" to do so themselves.
He said the United Nations expert on extrajudicial killings, Agnes Callamard, had without any proof "pictured me as a ruthless violator of human rights" who was directly responsible for extrajudicial killings.

In response to Duterte's decision, a majority of the Philippine senators signed a resolution declaring that termination or withdrawal from the agreement is only "valid and effective" with their consent.
According to ICC rules, it will now take one year for the withdrawal to take effect if the Philippines does not change its mind.
Lawyers say the withdrawal does not insulate Mr Duterte from a possible indictment, as the ICC's jurisdiction retroactively covers the period during which a country was a member of the court.

"I encourage the Philippines to remain as a party to the Rome Statute", he said in a statement. "Neither is it a crime of aggression or a crime against humanity", he said.
Albay Rep. Edcel Lagman (PL, Albay) said Duterte's refusal to be investigated by the ICC on charges of crimes against humanity "is a virtual admission of culpability since innocence does not select or discriminate a forum".
Article 127 of the Rome Statute states that even if a party withdraws from the treaty, it "shall not be discharged, by reason of its withdrawal, from the obligations arising from this Statute while it was a Party to the Statute, including any financial obligations which may have accrued".
Lagman expressed fear that the worldwide community will lose trust in the Philippines "because a country which does not honor its commitments does not deserve the trust of other states".
