A warranty clause is specifically designed to address post-acceptance defects. It defines the period during which the supplier guarantees their work and is obligated to remedy faults that arise, provided they originate from the original workmanship or materials. This directly matches the manager’s requirement.

The core risk is a lack of relevance. RPI is a general measure of consumer inflation. The costs for the specific goods (e.g., paper, ink, plastics) may be driven by different factors (like raw material commodity prices or logistics costs) that do not correlate with RPI, leading to inappropriate price changes for the buyer or supplier.

The correct first step is to formally manage the breach through notification. Ignoring it sets a bad precedent and waives contractual rights. Termination is disproportionate as a first step for a breach that may be rectifiable. A variation would reward non-compliance. Notification upholds the contract and allows for a structured resolution, which may involve seeking approval, assessing the subcontractor, or agreeing a variation.

The entire agreement clause aims to provide certainty. It states that the written contract represents the full and final agreement between the parties, superseding all prior discussions, correspondence, or promises. This helps prevent disputes where one party claims they were promised something not captured in the final signed document.

The doctrine distinguishing liquidated damages from penalties is key. A liquidated damages clause (a genuine pre-estimate of loss) is enforceable. A penalty clause (designed to punish, disproportionate to any likely loss) is not. Since the buyer suffered no real loss, the courts might view the repeated credits as a penalty, making them unenforceable. The clause must be a genuine pre-estimate of loss to be valid.

This argument is commercially sensible and persuasive. It acknowledges the supplier’s legitimate need to cap risk but challenges the proportionality of the cap. It focuses on the specific business impact (consequential production losses) to argue for a higher, more realistic limit that shares the risk more fairly, which is more likely to lead to a negotiated improvement than an outright demand for unlimited liability.

A Price Variation (VOP) clause is the standard contractual mechanism for managing price changes in longer-term contracts. It provides an objective, pre-agreed formula (often tied to labour, material indices, or currency rates) for adjusting prices. This balances the supplier’s need to cover cost increases with the buyer’s need for predictability and fairness, unlike informal methods or open-ended models like cost-plus.

Force majeure typically suspends obligations only for the duration of the event and a reasonable recovery period. The port strike is the event. Once it ends, the supplier is expected to resume performance. The backlog is a separate, commercial issue of their planning and capacity. The supplier is likely liable for delays caused by their failure to mitigate or manage the backlog after the external event ceased.

Certainty is a cornerstone of good contracting. A precise date removes ambiguity, sets clear expectations, and enables both parties to manage their finances accurately. The phrase ‘reasonable time’ is subjective and can lead to disagreements and strained relationships. Clear terms prevent such disputes.
