Animal Rights Africa has taken the Zulu monarch, King Goodwill Zwelithini, to court because it believes the killing of a bull in the Ukweshwama harvest ceremony is cruel.
Zulus say the animal is killed quickly and painlessly by breaking its neck.
Judge Nic van der Reyden said he could not be blind to the consequences of stopping a tradition that had been part of Zulu culture for centuries. He said the resulting protest could be similar to the 1976 Soweto uprising, in which black pupils rebelled against a government order that they be taught in Afrikaans.
Van der Reyden said he hoped his comments would encourage Animal Rights Africa, the Zulu king, KwaZulu-Natal Premier Zweli Mkhize and three government departments to a resolution to film the ritual and send the footage to Parliament for a decision.
"There are some points for consideration. Look at our history when authorities forced Afrikaans on those children. We need to resolve this through consultation," the judge said.
He will rule on Friday, a day before the ritual is to take place.
