Rehau Polymer (Pty) Ltd v Brunettes Electrical (Pty) Ltd and Others

Rehau Polymer (Pty) Ltd (Rehau) was the sub-lessee of factory premises in Uitenhage, Port Elizabeth, leased from the sixth respondent, Coega Development Corporation (CDC). In August 2008, Rehau entered into a written sub-lease agreement with CDC whereby CDC undertook to construct and lease a factory to Rehau for manufacturing polymer-based automotive components. The agreement contained warranties by CDC that the lease premises structures would be fit for purpose and would comply with all laws, legislation, regulations, rules and by-laws of all competent authorities relating to fire and health safety. During construction, the municipality's fire department required installation of a FM200 gas fire suppression system in the low voltage (LV) room. The system was installed, tested successfully on 18 September 2009 by the municipal fire safety official (Grobler), and a certificate of occupancy was issued on 22 September 2009. Rehau commenced full production. On 6 February 2010, a fire broke out in the LV room causing extensive damage. It was common cause that the fire suppression system required both electricity and gas to operate, but at the time of the fire the gas cylinders were not connected to the system, rendering it non-functional. Had it been functional, much of the damage would have been averted. The fourth and fifth respondents were held liable in delict for failing to advise Rehau and CDC that the gas cylinders were not armed. Rehau claimed damages from CDC based on breach of contractual warranties.

• Whether the failure to activate the gas fire suppression system constituted a breach of the warranties contained in clauses 9.1.1 and 9.1.8 of the sub-lease agreement
• Whether the lease premises structures complied with all laws, legislation, regulations, rules and by-laws of competent authorities relating to fire and health safety as warranted in clause 9.1.8
• Whether the lease premises structures were fit for purpose as warranted in clause 9.1.1
• Whether the interpretation of statutory provisions (National Building Regulations and Building Standards Act 103 of 1977 and the Nelson Mandela Bay Metropolitan Municipality by-law relating to fire safety) supported a finding of breach
• Whether the fourth and fifth respondents acted as agents of CDC for purposes of establishing CDC's liability
• The proper interpretation of the indemnity clause in the lease agreement

The appeal was dismissed with costs of two counsel. The High Court's dismissal of Rehau's claim against CDC was upheld by the majority.

The binding legal principle established by the majority is that warranties in a lease agreement relating to lease premises structures being fit for purpose and complying with fire and health safety regulations are limited to the condition of the structures at the time of completion and handover. Once a building has been erected in accordance with statutory provisions and a certificate of occupancy has been issued, the activation or deactivation of installed safety systems according to operational requirements does not affect compliance with such warranties. Sections 14(1) and 14(2A) of the National Building Regulations and Building Standards Act 103 of 1977 are concerned with the erection, design and installation of building systems, not with their operational status after completion. The warranty relates to the physical installation and compliance at handover, not ongoing operational maintenance. Where a fire suppression system is properly designed, commissioned and installed with no intrinsic defect, the failure to activate it after installation due to negligent omission by contractors does not constitute a breach of warranty by the lessor, even if those contractors were engaged by the lessor to install the system.

The majority judgment made obiter observations that the interpretation of statutes is a matter of law for the court, not a matter of fact for witnesses, and therefore the evidence of the municipal fire safety official regarding his interpretation of the National Building Regulations could not be determinative. The majority also commented that clause 9.1.3 of the warranties (relating to CDC not being in breach of obligations) was couched in the present tense at the time of signature, contrasting with other warranties in the future tense referring to completion, and related to the property rather than the Lease Premises Structures, thus having no application to the fire suppression system. The dissenting judgment of Mocumie JA made extensive obiter observations about: (1) the principle of non-delegability of duties in the context of Chartaprops Pty Ltd v Silberman, noting that while the application of non-delegability should be approached with caution, there are cases involving 'a relationship of special dependence or vulnerability' where a higher standard of care is required; (2) the nature of express warranties in contract law, citing Evans & Plows v Willis & Co for the principle that liability for breach of express warranty is independent of mala fides but depends upon what a party has expressly taken upon himself by contract; (3) that a warranty is a contractual term by which a party assumes absolute or strict liability for proper performance, such that he cannot rely on impossibility of performance or absence of knowledge or fault to escape liability. Makgoka JA in dissent made obiter observations emphasizing the importance of contextual interpretation, citing Natal Joint Municipality Fund v Endumeni Municipality, and noted that the purpose of a warranty would be undermined if the lessor's obligation was treated as a once-off event rather than ongoing and continuous for the duration of the lease agreement.

This case is significant in South African contract law for its interpretation of express warranties in lease agreements, particularly in the context of building compliance and fire safety. It demonstrates the tension between structural/construction obligations and ongoing operational obligations under a lease agreement. The majority judgment emphasizes that warranties relating to building structures apply to the condition at completion and do not extend to operational matters occurring after occupancy and handover. The dissenting judgments provide important alternative perspectives on: (1) the continuous nature of safety-related warranties; (2) the non-delegable duty of lessors in respect of fire safety compliance; and (3) the contextual interpretation of contractual warranties in light of regulatory requirements. The case also illustrates principles of agency in the construction context and the interpretation of indemnity clauses. The split decision (3-2) reflects the complexity of determining the scope and duration of contractual warranties in commercial lease agreements where regulatory compliance is required.
