Louis Theodor Christian Harms (born 11 October 1941) is a South African former deputy president of the Supreme Court of Appeal and Professor Extraordinary for Intellectual Property Law at the University of Pretoria.^[1][2]

Harms graduated from the University of Pretoria with a BA LL.B. (cum laude) in 1965 and the Hugo Grotius medal for best final year student.^[3] He was awarded a LLD (hon causa) from the University of the Free State and the University of Pretoria in 2013.^[4][5]

An advocate at the Pretoria Bar from 1966 to 1986, Harms was awarded senior advocate status in 1981 and appointed as a judge in 1986.^[3] He served as a Judge of Appeal in the Supreme Court of Appeal from 1993 to his appointment as Deputy President of the Supreme Court of Appeal in 2008, a position he held until his retirement in 2011.^[2] He is infamous as the author of the Harms Report. Asked by President F.W.DeKlerk to investigate the State controlled death squads and political murders he set up what is known as the Harms Commission of Inquiry (Feb-Sept 1990). Suspected collusion with the apartheid state was implied after the release of the final report which denied the existence of death squads contradicted later by the mountains of evidence to the contrary uncovered by the Truth and Reconciliation Commission (TRC). The records at WITS University concluded: "The Harms Commission report, which was released in September 1990, failed to name any special units of the army or police, let alone any individual officers, as participants in the death squads. The report was denounced by opposition groups as a whitewash."http://historicalpapers-atom.wits.ac.za/harms-commission-of-inquiry-records;isad?sf_culture=en
