Israel's representative was conspicuously missing when the UN Human Rights Council started a special session today on the situation in the Palestinian territories and the 2014 Gaza conflict.
"I note the representative of Israel is not present," said Council President Joachim Ruecher.
Israel provided no immediate explanation for not being present at the session dedicated overwhelmingly to discussion of its policies and alleged abuses, but a source close to the council said its absence clearly amounted to a boycott.
The United States was also absent from today's discussions.
Asked to explain why the United States was not taking part, a spokesman said only that the US ambassador to the council Keith Harper was in Washington.
"The process cannot be rushed," former New York judge Mary McGowan Davis, who has taken over as head of the team, told the council.
Schabas strongly denied that he was beholden to the PLO but said he was reluctantly stepping down to avoid the inquiry into the July-August conflict, commissioned by the UN Human Rights Council, being compromised in any away.
Israel was not satisfied, calling for the entire inquiry to be shelved, insisting the commission and the Human Rights Council which created it are inherently biased against the c state.
It is the only country in the world with a special agenda item dedicated to it, meaning its rights record is discussed at every session of the UN's top rights body.
It cut all ties with the council in March 2012 over its plans to probe how Jewish settlements were harming Palestinian rights, and did not resume relations until late 2013.
The US absence today sparked speculation over whether it aimed to avoid having to stick up for Israel, as it usually does, amid cooling relations between the two allies.
Washington warned last week it could withdraw its unwavering support for Israel at the UN over Netanyahu's tough stance on the Palestinians.
A number of states meanwhile saw the absence of the United States and most western nations from today's debate in a different light.
This is "a deliberate attempt to undermine the credibility of the Human Rights Council," said Pakistan's representative, speaking on behalf of the Organization of the Islamic Conference.
Although the report on the 2014 Gaza war investigation was delayed until June, the UN's new Special Rapporteur on the situation in the Palestinian territories did not hold back.
"The ferocity of destruction and high proportion of civilian lives lost in Gaza cast serious doubts over Israel's adherence to international humanitarian law principles of proportionality, distinction and precautions in attack," Makarim Wibisono told the council.
He lamented "acute" needs in Gaza, warning that Israel's continued "blockade keeps Gaza in a stranglehold which does not even allow people to help themselves."
The Gaza conflict ended with a truce between Israel and the territory's Islamist de facto rulers Hamas on August 26 after the deaths of more than 2,140 Palestinians, most of them civilians, and 73 people on the Israeli side, mostly soldiers.
