Yes, an Argentine Nazi hunter is just what the dead, the dying, the maimed and homeless of Gaza need. Yes, it will be a fair and just hearing, that I see in my crystal balls.
After graduating from the University of the Witwatersrand with a BA LLB cum laude in 1962 he practised as an Advocate at the Johannesburg Bar. In 1976 he was appointed Senior Counsel and in 1980 was made Judge of the Transvaal Supreme Court.
Overseeing the South African apartheid sadists from his lofty perch on the Transvaal Supreme Court. SA apartheid didn't end till 1994.

Israel came into existence in 1948 and so did South Africa's sadistic apartheid regime. Do the brutalization and insults to Palestinians never stop? Appointing a South African Jew to investigate the war crimes of the Israeli Jews?

Wasn't Alan Dershowitz available?

Xymphora's blog nailed it succinctly.
The head of the inquiry is Richard Goldstone

"A Jewish South African with close ties to Israel will head a U.N. inquiry into war crimes during Israel's recent war with Hamas in the Gaza Strip.

Richard Goldstone, a trustee of Hebrew University, will head the commission appointed Friday by the U.N.'s Human Rights Council.

Israel did not say whether it will cooperate; it has in the past ignored other UNHRC probes, noting the body's tendency to single out Israel for criticism while ignoring other major violators.

Goldstone, who headed war crimes prosecutions in Rwanda and the former Yugoslavia, said he would investigate alleged war crimes by both sides.

"It's in the interest of the victims," Goldstone said in Geneva, where the UNHRC is headquartered. "It brings acknowledgment of what happened to them. It can assist the healing process."

He said his Jewishness and ties to Israel were added values. "I've taken a deep interest in what happens in Israel," he said. "I'm associated with organizations that have worked in Israel. And I believe I can approach the daunting task that I have accepted in an evenhanded and impartial manner.""

Goldstone is at least decent enough to pronounce himself shocked at the audacity of his own appointment.

Another member is Christine Chinkin, of Matrix Chambers, a group which also includes Cherie Blair, whose husband's pockets still jingle with all those shekels from the Dan David Foundation.

Another is Irish Army Col. Desmond Travers, associated with the Institute for International Criminal Investigations (note the Goldberg quote), part of the Human Rights Industrial Complex (HRIC) centered in The Hague, where the International Criminal Court recently outed itself as a covert JIZ operation with its indictment of Sudanese President Omar al-Bashir.

And finally Pakistani lawyer Hina Jilani, who has been involved in the investigation of human rights abuses in Darfur as a member of the International Commission of Inquiry on Darfur (and is also connected to the Institute for International Criminal Investigations: it is quite a cozy group), needless to say part of the wider JIZ initiative to have Britain and the United States attack Sudan for the crime of being a Muslim country that doesn't like Israel.
That White Phosphorous Israel used against Gazan civilians? Just that "light unto the world" using WP to well, light up Gaza, that's all, no crime here.
