Commercial risk often enters the project through ordinary communication long before anyone calls the lawyers.
A project team can create legal exposure while believing it is only negotiating.
A supplier submits a tender. The buyer counters. A project manager asks whether an offer can remain open. A letter is posted. A contractor is promised additional money to meet an existing deadline. People act in reliance on what they believe has been agreed.
The supplied assignment uses exactly these kinds of scenarios: tender rejection, competing IT offers, postal acceptance and an additional payment promised to a contractor that was already obliged to finish by the original date.
The assignment’s legal conclusions are not treated here as authoritative. Some require correction or independent legal verification. The value of the material lies in showing where project behaviour intersects with contract law.
FACT CHECK REQUIRED: Current Australian contract-law treatment of invitation to treat/tender process contracts, postal acceptance, counteroffers, consideration for contract variations, practical benefit, economic duress, estoppel and remedies should be independently verified before publication.
The Strategic Context
Project managers routinely communicate about scope, time, price and performance.
Those communications can affect legal rights.
The project environment increases the risk because decisions are often time-sensitive. People try to preserve schedule by agreeing verbally, confirming by email later or instructing work before commercial terms are complete.
This creates a dangerous gap between operational intent and legal effect.
The goal is not to turn every project manager into a lawyer. It is to make leaders recognise when an apparently practical conversation has crossed into a commercial commitment.
What Leaders Commonly Misread
Tendering is legally irrelevant until a contract is signed
That is too simple.
Depending on the process and jurisdiction, tender documents, process promises and communications can have legal consequences even if the ultimate project contract has not yet been formed.
The supplied airport case raises this risk through minimum requirements, competing tenderers and tender-preparation cost.
The correct legal conclusion cannot be assumed from the student response.
An offer can stay open because someone informally said it probably would
Commercial teams need clarity about whether an offer is open, revocable, accepted, rejected or countered.
Ambiguous language invites later disagreement.
A counteroffer is only “continuing the conversation”
It may have legal consequences for the status of the previous offer. The exact rule and application depend on the facts and applicable law.
Promising extra money always creates an enforceable variation
Not necessarily.
The supplied contractor scenario raises the difficult issue of an existing contractual duty: the contractor was already required to meet the original completion date, yet the buyer later promised additional payment if it did so.
The student assignment characterises the issue through undue influence, but that should not be relied upon as the correct doctrine. The relevant analysis requires current legal verification.
Reframing the Issue
The practical management question is:
When does project communication change legal or commercial position?
There are four recurring risk zones.
Market communication
Tender documents, clarifications, representations and evaluation commitments can shape expectations and rights.
Negotiation
Offers, counteroffers, deadlines and acceptance need clear status.
Instruction
Requests to perform additional or changed work can create entitlement disputes if authority and price are not controlled.
Recovery
When a project is under pressure, parties may promise acceleration payments, extensions, waivers or concessions. These are precisely the moments when legal discipline matters most.
Strategic Analysis
Separate operational urgency from contractual authority
A schedule problem does not expand delegated authority.
The person closest to the technical issue may be the least appropriate person to make a commercial commitment. Escalation pathways should be faster than the temptation to improvise.
Preserve evidence
Contract disputes are often disputes about what was said, when and by whom.
Clear written records of offers, clarifications, instructions, approvals and reservations protect both sides.
Use defined communication channels
Contracts commonly specify notice mechanisms, authorised representatives and formal procedures.
Project teams should understand which communications are informational and which can create contractual effect.
Escalate unusual changes early
A request for a supplier to perform outside the agreed basis, accelerate materially, absorb unexpected cost or rely on a non-standard promise should trigger commercial and legal review.
Waiting until the work is complete reduces options.
Distinguish fairness from enforceability
A project team may feel morally certain that one party “should” be paid or “should” bear a loss.
Contract law can reach a different conclusion.
Leadership decisions should therefore separate commercial fairness, relationship strategy and legal entitlement rather than assuming they are identical.
A Governance Principle: Do Not Let Urgency Define the Legal Position
The scenarios in the supplied assignment share a common feature: people are making commercially significant statements while trying to solve an immediate project problem.
That is normal project behaviour. It is also why governance must be designed for pressure.
If formal approval takes two weeks but a site decision is needed today, teams will find another path. The solution is not merely to remind them of policy. It is to create controlled mechanisms for urgent decisions, such as delegated thresholds, documented interim instructions or rapid commercial escalation.
The legal risk is therefore partly a process-design risk.
Project leaders should also distinguish between legal entitlement and negotiated settlement. A party may have a defensible legal position yet choose a commercial compromise to protect schedule, relationship or litigation cost. Conversely, a desire to preserve a relationship should not lead staff to make commitments they are not authorised to make.
FACT CHECK REQUIRED: Any published example that describes the legal effect of a specific communication should be reviewed against current Australian law and the governing jurisdiction.
The practical objective is not to eliminate judgement. It is to ensure judgement occurs with clear authority and awareness of its legal consequences.
Decision Framework
Use a simple commercial-commitment test before significant communication.
Authority: Am I authorised to make or change this commitment?
Clarity: Is the proposal sufficiently clear about scope, price, time and conditions?
Status: Is this an inquiry, negotiation, offer, acceptance, instruction or variation?
Evidence: Is there a reliable written record?
Dependency: Will the other party act or spend money in reliance on this statement?
Legal review: Does the issue involve unusual legal effect, disputed entitlement or material value?
If uncertainty exists on the final two questions, stop informal escalation and obtain appropriate commercial or legal advice.
From Strategy to Execution
Immediate action: identify project roles that communicate directly with suppliers and ensure they understand delegated authority and formal instruction mechanisms.
Medium-term capability: create concise commercial-communication rules for tenders, negotiations and post-award changes. These should complement, not replace, legal advice.
Long-term positioning: analyse disputes and claims for behavioural root causes. If the same legal issues arise repeatedly, the organisation may have an authority or governance problem rather than isolated bad luck.

Signals to Monitor
Warning signals include phrases such as “we will sort the commercial side out later”, suppliers beginning changed work before a variation is approved, informal commitments to keep offers open, project staff negotiating outside formal channels or legal review being requested only after a dispute has crystallised.
Another signal is when multiple team members have different interpretations of whether a deal has been agreed.
That ambiguity is itself a risk.
Questions for the Leadership Team
- Who on this project can make contractual commitments?
- Which tender communications could create expectations beyond the final contract?
- How are offers, counteroffers and acceptance recorded?
- Can work begin before commercial approval, and if so under what controlled mechanism?
- Which current disputes began as informal efforts to protect schedule?
- At what value or risk threshold is legal review mandatory?
Closing Perspective
Contract law becomes a project issue whenever words alter obligations.
The solution is not legalistic paralysis. It is disciplined communication, clear authority, strong records and early escalation when a situation moves beyond routine administration.
The supplied case material is useful precisely because its legal conclusions are contestable. That is the point project leaders should remember: what appears obvious operationally may not be obvious legally.
For material commitments, commercial certainty should be created deliberately rather than discovered later in a dispute.
