Premier Attraction 300 CC t/a Premier Security v City of Cape Town

Premier Attraction 300 CC t/a Premier Security (Premier) tendered successfully to render security services to the City of Cape Town (the City) for six years from 1 October 2008 to 30 September 2014. Contract prices for the first two years were agreed without dispute. Price increases for subsequent years depended on sectoral determinations issued by the Minister of Labour under the Labour Relations Act 66 of 1995. When such increases occurred, Premier could apply to the City for price variations. From October 2010 to September 2014, a dispute arose regarding how to calculate price increases. Premier applied for increases based on its interpretation of the contract and submitted invoices accordingly. The City disagreed with Premier's calculations and rejected these invoices. Premier then submitted invoices based on the City's calculations, believing the City would not pay otherwise, though it never communicated its disagreement to the City during this period. Premier faced financial difficulties when the third phase contract diminished by more than two-thirds. After the contract expired in September 2014, Premier first communicated its intention to claim the alleged shortfall at a meeting on 9 December 2014, and demanded payment on 14 January 2015. The City denied liability on 18 February 2015. On 24 June 2015, Premier notified the City of its claims under The Institution of Legal Proceedings Against Certain Organs of State Act 40 of 2002, conceding the notice was not sent within six months of the debt becoming due. On 25 June 2015, Premier applied urgently to the high court for payment of both the main claim (R16,469,681.94) and an additional claim (R2,339,296.27).

• Whether Premier waived its right to claim contract prices based on its own interpretation and calculations by consistently invoicing on the City's calculations without objection
• Whether Premier's claims for alleged shortfalls had prescribed under the Prescription Act 68 of 1969, particularly for amounts falling due between 1 September 2010 and 25 June 2012
• Whether the City properly pleaded and proved the defence of waiver
• Whether condonation was properly granted for non-compliance with the Institution of Legal Proceedings Against Certain Organs of State Act 40 of 2002
• The correct interpretation of the contract regarding price escalation calculations

The appeal was dismissed with costs, including costs of two counsel. The high court's dismissal of Premier's main claim (R16,469,681.94) was upheld on grounds of waiver and prescription. The high court's award of the additional claim (R2,339,296.27) in Premier's favour stood, as the City did not cross-appeal against it.

1. A party waives its contractual rights when it has full knowledge of those rights, fails to act positively to enforce them when under a positive duty to do so, and by its conduct objectively manifests an intention inconsistent with the continuance of those rights. 2. When faced with a choice between contesting an interpretation of contract terms or abiding by the other party's interpretation, a party that elects to abide by invoicing and accepting payments on the other party's interpretation waives its right to later claim on its own interpretation. This constitutes an election between bipolar options – one cannot approbate and reprobate. 3. Silence and inaction can constitute waiver where circumstances impose a positive duty to act or speak to dispel any inference of acquiescence. 4. For purposes of the defence of waiver, it is sufficient for the defending party to set out the relevant facts adequately in its pleadings, provided the other side has a fair opportunity to respond. Waiver is a defence on a point of law that can be raised on the facts. 5. For purposes of prescription under the Prescription Act 68 of 1969, a debt becomes "due" when the creditor has completed the procedures required for payment under the contract (such as submitting invoices in accordance with payment procedures), regardless of whether the creditor knows the legal conclusions arising from the facts. 6. Knowledge required under s 12(3) of the Prescription Act does not include knowledge of legal conclusions by the creditor before a debt can be said to be due. 7. A debt extinguished by prescription cannot be revived after expiry of the prescriptive period through allocation of subsequent payments to the prescribed debt. 8. Where a court's intention to grant condonation is unmistakable from its judgment, the absence of an express order granting condonation does not invalidate the court's substantive decision on the merits.

1. The court observed that legal representatives have a duty to seriously and genuinely engage each other under Rules 8(8) and (9) of the Supreme Court of Appeal Rules to agree on issues and portions of the record relevant for appeal. This requirement serves the interests of costs, convenience, efficient use of time and resources, and the greater interest of dispensing justice. 2. The court noted with criticism that the parties' legal representatives, particularly the City's, failed to properly implement Rule 8 by including 3764 invoices in the record that were entirely irrelevant to a case turning on contract interpretation. Senior and junior counsel on both sides could not possibly have concluded that judges would "trawl through 3764 invoices to determine pricing" with "calculator in one hand, a magnifying glass in the other." 3. The court warned that legal representatives who fail to properly comply with rules regarding record preparation risk being mulcted with costs. 4. The court addressed the City's argument about condonation and cross-appeal, noting that if the City genuinely wanted to cross-appeal, it could have invoked Rule 42(1)(b) of the Superior Court Practice to cure any ambiguity, error or omission in the high court's order. Having failed to adopt "a sensible and inexpensive approach," the City could not be allowed to unravel the entire judgment. 5. The court distinguished Mohamed v President of the RSA, where the appellant was unaware of his rights and lacked access to legal advice, from the present case where Premier knew its rights and had access to lawyers. 6. The court distinguished Greathead v SA Commercial Catering and Allied Workers Union, where abandoning a law point not previously considered was not waiver, from the present case involving conscious and deliberate conduct in rendering invoices. 7. The court analogized Premier's conduct to the deliberate act of depositing a cheque in Collen v Rietfontein Engineering Works, noting that in both instances acceptance of the other side's offer was by conduct.

This case is significant in South African contract law and administrative law for several reasons: 1. It provides clear guidance on the doctrine of waiver in contractual disputes, particularly in the context of public procurement contracts with organs of state. 2. It clarifies the objective test for waiver, emphasizing that silence and inaction can constitute waiver when there is a positive duty to act or speak. The court reinforced that mental reservations not communicated have no legal effect. 3. It establishes that election between bipolar contractual options (to contest or abide by terms) constitutes waiver, applying the principle that one cannot approbate and reprobate. 4. It confirms the application of prescription principles to contractual claims, clarifying when debts become "due" for purposes of the Prescription Act 68 of 1969, particularly in the context of invoicing and payment procedures. 5. It demonstrates the knowledge requirement under s 12(3) of the Prescription Act, following Mtokonya v Minister of Police, that knowledge of legal conclusions is not required before a debt is deemed due. 6. It provides practical guidance on substance over form in judicial orders, finding that condonation can be granted even if not expressly stated in the formal order where the court's intention is clear from the judgment. 7. It emphasizes the importance of compliance with Rules 8(8) and (9) of the Supreme Court of Appeal Rules regarding preparation of appeal records, warning legal practitioners about including irrelevant material and the risk of cost consequences. 8. The case serves as a cautionary tale for contractors dealing with organs of state to timeously invoke dispute resolution mechanisms and not to silently accept payments they consider inadequate while reserving rights for later assertion.
