Philippine President Rodrigo Duterte has unleashed a barrage of insults against global human rights officials, calling a United Nations special rapporteur "malnourished", and referring to an worldwide Criminal Court (ICC) prosecutor as "that black woman", prompting the United Nations human rights chief to call for his "psychiatric evaluation".
"This is absolutely disgraceful that the president of a country could speak in this way, using the foulest of language against a rapporteur that is highly respected", Mr Zeid added. "I'm very tempted to respond in similar language, but I have opted to restrain myself, opting not to respond in the same abominate used by the UN High Commissioner", Roque said.
Speaking at a press briefing on Saturday, Roque stressed Zeid's language towards Duterte was not just an insult towards the President, but towards the whole nation.
Roque, meanwhile, said Zeid's language was an insult to all countries with democratically-elected state leaders.
"I will, however, state that perhaps the United Nations high commissioner's language is because of the fact that they have no democracy in his own state of Jordan".
President Rodrigo Duterte previously enjoyed a good relationship with the communist movement, freeing some of the movement's leaders when he took office in July 2016 to show his commitment to resolving the five-decade conflict.
Roque instead retorted back with a criticism of his own: that Zeid's home country of Jordan is undemocratic.
UN High Commissioner for Human Rights Zeid Ra'ad al-Hussein defended the independence, impartiality and expertise of special rapporteurs in the face of smear and hate campaigns, some involving incitement to violence.
According to Zeid, Ms. Corpuz believes that she has been targeted because of her comments on the attacks and killings of indigenous people in Mindanao.
Cayetano said Zeid's remarks "could set a unsafe precedent that the Council would have to immediately address as otherwise member-states could also fall victim to those who seek to politicise and weaponise human rights to undermine legitimate governments". He has also taken aim at International Criminal Court prosecutor Fatou Bensouda, who announced last month that she was opening a preliminary examination into alleged extrajudicial drug killings.
The Philiphines justice ministry in February said it wanted a Manila court to declare the Communist Party of the Philippines (CPP) and its armed wing, the New People's Army (NPA), "terrorist" bodies, but made no mention of individuals it would also target.
Malacañang on Saturday said the inclusion of Tauli-Corpuz in the government's "terrorist" list is based on intelligence information and not part of a "witch hunt". "This move therefore by the DoJ only reinforces the classification that the CPP-NPA is a terrorist group", he said.
"Ms Tauli-Corpuz is a human rights defender", the experts said.
"We will accord Victoria Tauili Corpuz the right to be heard, her inherent due process rights".
This "terrorist tag further worsens the fragile state of indigenous peoples" human rights in the country. "She can dispute the classification in the Regional Trial Court where the petition to declare the CPP-NPA as a terrorist group is now pending", Roque said.
