African National Congress Youth League (ANCYL) leader Julius Malema has been notified to appear at an investigative hearing to answer allegations of hate speech lodged against him for his "shoot the boer" song, the Human Rights Commission said on Thursday.

This after it received various complaints alleging that utterances made by Malema at events between January and April had incited violence and infringed on the right to equality and human dignity.

"The commission (will) be calling the complainants and/or their representatives...and a cross section of relevant experts...to the hearing," deputy director Eric Mokonyama said in a letter to the Afrikanerbond, one of the organisations that complained.

Mokonyama told Sapa on Thursday that a date for the hearing still had to be set and he was unsure if it would be held this year.

"We have to take into consideration a number of factors...and (the) number of people that would have to be called in," he said.

Afrikanerbond chief secretary Jan Bosman said that he welcomed the resolution for a hearing after "a frustratingly long delay".

He had lodged several complaints against Malema accusing him of violating several basic and universal rights with his "shoot the boer" song.

Bosman said that the controversial youth leader sang "dubulu iBhunu" on March 9 at a gathering at the University of Johannesburg and again on March 22 in Mafikeng.

The bond also lodged a complaint about Malema's outburst and use of vulgar language directed at a BBC correspondent at a press conference in Luthuli House on April 8.

"It is extremely important - for the sake of the promotion and protection of human rights in South Africa - that the Human Rights Commission now make a ruling on the violation of human rights as this is happening more often and more frequently," Bosman said.

"Hopefully the HRC, as the guardian and custodian of human rights in SA, will hold the investigative hearing as soon as possible."
