The case of Finnigan v New Zealand Rugby Football Union was an attempt to prevent a proposed rugby tour to South Africa in 1986. South Africa's apartheid regime was subject to international sanctions, including calls for a sporting boycott. There were tumultuous protests against a tour by the Springboks to New Zealand in 1981. However, the NZRFU was technically a private body, and only people with a special interest affected by a decision of that body had legal standing to bring a court case against the Union. This lecture examines how the courts mediated the dynamic between public interest and private bodies in the Finnigan case.
