PriceWaterhouseCoopers Inc & others v National Potato Co-operative Ltd & another

PriceWaterhouseCoopers Inc (PWC Inc) and four predecessor firms (collectively PWC) acted as auditors for National Potato Co-operative Ltd (NPC) from 1984 to 1997. NPC alleged that PWC breached their contractual obligations as auditors by failing to properly audit its financial statements and failing to identify reckless mismanagement of credit and inadequate provisions for bad and doubtful debts. NPC claimed that if PWC had properly performed their duties, they would have discovered mismanagement and either insisted on changes to the financial statements or qualified their audit reports. NPC sought to recover R62,884,905.45 in bad debts written off, arguing that had PWC properly audited, remedial measures would have been instituted to prevent these losses. The trial took 264 days on merits and 31 days on quantum, producing judgments of nearly 1100 pages. The trial court found in favor of NPC. PWC appealed. The second respondent, IMF (Australia) Ltd, was a litigation funder that had taken over funding of the case and stood to receive over 55% of any proceeds.

• Did a contractual relationship exist between PWC and NPC or was the auditor's appointment purely statutory?
• What were the contractual obligations of PWC as statutory auditors under the Co-operatives Act 91 of 1981?
• Did NPC prove reckless mismanagement of credit by its officials?
• Was the evidence of Mr Collett admissible as expert evidence and/or hearsay?
• Did PWC breach their contractual obligations in conducting the audits?
• Did any breach by PWC cause NPC to suffer the losses claimed?
• What is the proper causation test where a company claims damages from auditors for failing to report problems that allegedly would have been remedied?
• Had NPC's claim prescribed under the Prescription Act 68 of 1969?
• Whose knowledge is attributed to a corporate entity for purposes of prescription when claiming against auditors?
• What are the duties and standards applicable to expert witnesses?
• When should a trial court intervene to prevent inadmissible hearsay evidence from dominating a trial?

The appeals by PWC and PWC Inc were upheld with costs including two counsel. The judgments of the court below were set aside and replaced with an order dismissing NPC's claim with costs. The cross-appeal by NPC was dismissed with costs including two counsel. Several subsidiary costs orders made by the trial court were also set aside and replaced with orders in favor of the appellants. Costs orders were made jointly and severally against both respondents (NPC and IMF).

The binding legal principles established are: (1) A statutory auditor's appointment creates a contractual relationship with the audited entity, with each annual appointment constituting a separate contract. Each breach must be considered independently. (2) For expert evidence to be admissible, the witness must have genuine expertise in the relevant field, base opinions on proven facts (not hearsay), maintain independence, and not act as an advocate for the party calling them. (3) In professional negligence claims against auditors based on alleged failure to report problems, the plaintiff must prove: (a) the specific facts giving rise to the duty to report; (b) breach of that duty; (c) that had proper reports been made, specific remedial action would have been taken; and (d) that such action would have prevented the specific losses claimed. (4) Losses arising from a company's ordinary trading activities and business decisions are not recoverable from auditors merely because better audit reports might have prompted different decisions. There must be a direct causal link between the audit failure and the loss. (5) For prescription purposes under s 12(3) of the Prescription Act, when a corporate entity claims against its auditors, the knowledge of the entity's directors (actual or constructive through reasonable care) is attributed to the entity. There is no special rule that only shareholders'/members' knowledge is relevant in claims against auditors. (6) Trial courts have a duty to intervene to prevent proceedings from being dominated by inadmissible hearsay evidence, even where parties have agreed to defer objections.

The court made several important obiter observations: (1) Wallis JA expressed concern about litigation funding arrangements where an outside funder unconnected to the dispute and motivated solely by profit may be the sole beneficiary of a judgment, questioning whether this engages the constitutional guarantee of access to courts and suggesting the court's earlier decision on champerty may need reconsideration. (2) The court criticized the manner in which the trial was conducted, noting it assumed unnecessary complexity due to: improper leading of expert evidence by taking witnesses through lengthy summaries rather than focusing on key issues; excessive and often pointless cross-examination; failure to call factual witnesses who had personal knowledge; and allowing one witness (Mr Collett) to give inadmissible evidence on matters far beyond his expertise. (3) The court emphasized that trial judges must exercise control over proceedings to prevent them from becoming unmanageable, including by: requiring prompt applications for admission of hearsay evidence; requiring expert evidence to follow factual evidence; preventing witnesses from testifying beyond their expertise; and limiting prolixity in examination. (4) The court noted that expert reports should generally be treated as evidence-in-chief subject only to supplementary questions for clarification, not read through in detail. (5) The court commented that compliance with GAAS may be necessary but not sufficient to avoid breach of contract if statutory obligations are more stringent. (6) The court expressed sympathy for the trial judge dealing with such a complex case but noted the judge should have intervened earlier to control the proceedings.

This case is significant in South African law for several reasons: (1) It clarifies that the relationship between a statutory auditor and a company/co-operative is contractual, not purely statutory, with each annual appointment creating a separate contract. (2) It establishes important principles regarding expert evidence, emphasizing that experts must be truly qualified, independent, and base opinions on proven facts, not act as advocates. (3) It reinforces strict causation requirements in professional negligence claims against auditors - the plaintiff must prove the specific losses would not have occurred but for the breach. (4) It confirms that losses arising from ordinary trading decisions cannot be recovered from auditors merely because better reporting might have prompted different decisions. (5) It clarifies that for prescription purposes in claims against auditors, knowledge of directors (not just shareholders/members) is attributed to the corporate entity. (6) It demonstrates the courts' willingness to interfere with trial proceedings to prevent inadmissible hearsay evidence from dominating a case. (7) It addresses issues around litigation funding and raises concerns about third-party funders being the primary beneficiaries of judgments. The case also serves as a cautionary tale about trial management, showing how failure to deal expeditiously with evidentiary objections can lead to protracted, costly litigation.
