Bokoni Platinum Mines (Pty) Ltd v Abram Moropane

Bokoni Platinum Mines commenced mining activities on Klipfontein Farm in 2013 and concluded agreements with subsistence farmers, including Mr Moropane, to pay each R54,000 over three years (R18,000 annually) as compensation for farming on the land. Bokoni paid the first installment but refused further payments. Mr Moropane sued for the remaining R36,000. The matter proceeded to trial before Magistrate Malebane. During trial, Bokoni's case shifted after its witness admitted written agreements existed. Bokoni then sought to amend its plea and counterclaim on 27 October 2016. On 13 March 2017, Magistrate Malebane dismissed the application for leave to amend. Bokoni subsequently applied for and obtained Magistrate Malebane's recusal on grounds of bias on 25 April 2017, with an order that the matter start de novo. Bokoni withdrew its appeal and served a new notice of amendment. The new application was heard before Acting Magistrate Moyane who also refused the amendment. Bokoni appealed to the High Court, which raised res judicata mero motu, holding that Magistrate Malebane's judgment remained binding despite his recusal.

• Whether a recusal based on judicial bias nullifies all proceedings before the recused judicial officer, including interlocutory judgments
• Whether the judgment refusing leave to amend by a recused magistrate was res judicata and could bind subsequent proceedings
• Whether res judicata could be raised mero motu by an appellate court
• The legal effect of a recusal on the basis of bias on prior proceedings and orders

1. The appeal was upheld. 2. The proceedings before Magistrate Malebane were set aside, including the judgment refusing leave to amend the plea and counterclaim. 3. The matter was remitted to a full court of the Limpopo Division of the High Court to adjudicate Acting Magistrate Moyane's judgment on the merits of the application for leave to amend the plea and counterclaim. 4. Each party was ordered to pay its own costs.

As a general rule, a recusal on the basis of bias will permeate and invalidate every aspect of a trial, including the judgments and orders made in the course of the trial. Once a judicial officer recuses himself or herself on grounds of bias, the entire proceedings become a nullity from the start, not merely proceedings after the recusal. Bias is fundamentally inimical to the fair hearing requirement and renders proceedings incompetent from the outset. It is unsustainable to hold that a recusal nullifies evidence but not interlocutory judgments given on the basis of that same evidence. Unbiased adjudication is an irreducible prerequisite of fairness, and a biased adjudication will not be countenanced by law regardless of whether it may have reached a correct result. One cannot cure a nullity.

The Court noted that there may be unique circumstances where the rationale for recusal has limited impact and nullifying entire proceedings would not be in the interests of justice, but such limitations were not argued and would not apply to the present case. The Court observed that the distinction sometimes drawn in authorities between nullifying proceedings before versus after recusal was put to rest in Basson v Hugo. The Court also commented that the observations in Le Car Auto Traders v Degswa regarding prospective effect of recusal were obiter and related to very special facts involving an unmeritorious recusal application made after judgment. The Court noted that there is no coherent reason why civil litigants should have a lesser claim to an unbiased hearing than parties in criminal proceedings, and the principle of nullity should apply equally to both.

This judgment provides important clarification on the legal consequences of judicial recusal based on bias in South African law. It establishes that recusal on grounds of bias does not merely affect prospective proceedings or evidence, but invalidates all proceedings and orders made by the biased judicial officer, including interlocutory judgments. The case reinforces the fundamental constitutional principle that impartiality is an irreducible prerequisite of a fair hearing under section 34 of the Constitution. It confirms that this principle applies equally to civil and criminal proceedings. The judgment provides guidance on the scope of nullity following recusal and rejects the notion that some aspects of biased proceedings can stand while others fall. The case also illustrates the importance of correctly framing the legal enquiry on appeal.
