Reliance Damages and Wasted Expenditure

Reliance and Expectation Measures Compared

A reliance calculation starts with wasted expenditure, while an expectation calculation measures the position promised performance would have produced. Both remain subject to the compensatory principle. The claimant cannot receive more than the position performance would have delivered.

In Commonwealth v Amann Aviation Pty Ltd [1991] HCA 54, the High Court considered expenditure on aircraft and preparations for a surveillance contract. The case shows why uncertain profits do not automatically defeat a wasted-expenditure claim. It also shows why residual asset value and the prospect of recovering expenditure through performance require attention.

Before preparing figures, identify the pleaded obligation, the breach and the purpose of each expense. A supplier’s failure to deliver equipment requires a different expenditure inquiry from a failure to meet a promised operating capacity.

Keep the alternative expectation damages calculation in a separate schedule. Adding a full performance-based award to the same wasted expenditure counts the same loss twice. Separate heads can coexist only to the extent they compensate distinct loss without overlap.

Identify Expenditure Incurred in Reliance

Identify reliance expenditure by tracing each commitment through its invoice to payment and explaining how it depended on the contract’s performance. Keep the promise that prompted the expense beside the source records.

Create a chronology with separate entries for commitments and cash movements. A purchase order records an order. An invoice records an amount claimed by a supplier. A statement records payment, which can settle several invoices or only part of one.

Use separate groups when assembling the records:

• Pre-contract spending, with the reason it was incurred in anticipation of the eventual contract.
• Spending during performance, matched to the work or preparation it funded.
• Liabilities still payable, with the agreement and evidence supporting the amount.
• Future spending cancelled or avoided when the transaction ended.
• General business expenditure that would have occurred even without this transaction.

Pre-contract timing alone does not resolve recoverability. Retain the evidence of anticipated performance and the parties’ knowledge for the solicitor’s assessment. Likewise, paying an existing general overhead from the project account does not establish that the breach wasted it.

Where a payment covers several jobs, attach the allocation calculation. For a $12,000 payment covering three separately invoiced projects, include only the portion supported for this contract. Keep the total bank debit visible so the allocation can be reconciled.

Record cancelled commitments separately from unpaid liabilities that remain enforceable. An unplaced $20,000 order is not $20,000 spent. If its cancellation leaves a $2,000 charge, retain the cancellation terms and charge as a distinct item for assessment.

Test Benefit, Recoupment and Overlap

Reduce the expenditure calculation for relevant benefits retained and examine whether performance would have recovered the expenditure. The label “reliance” does not remove evidence of a loss-making bargain.

In Cessnock City Council v 123 259 932 Pty Ltd [2024] HCA 17, the plurality explains the approach at paragraph 61. The claimant keeps the legal burden of proving loss. Where the breach causes or increases uncertainty about the performance position, proof can be assisted by an inference that reasonable reliance expenditure would have been recovered. The inference’s strength depends on that uncertainty. Evidence against recoupment can rebut it wholly or partly.

This requires more than a list of payments. Preserve forecasts and contemporaneous evidence of expected use, alongside evidence supporting any claimed residual benefit. Keep adverse trading evidence in the material supplied for assessment.

Fictional Equipment-and-Supplier Transaction

Assume a manufacturer contracts for a specialised machine. The supplier repudiates before delivery. The manufacturer has paid the following project costs, all on a consistent basis excluding recoverable GST.

The supplier refunds $15,000. The materials sell for $4,000 after selling costs. An agreed valuation puts the foundations’ remaining benefit at $6,000. Assume these benefits concern separate expenditure and the training has no remaining use.

The provisional net expenditure is $50,000: $75,000 less $15,000, $4,000 and $6,000. Keep the refund and resale receipts as separate credits, each cross-referenced to the expenditure it reduces.

A further $12,000 invoice for a cancelled installation has been withdrawn without charge. It contributes nothing to the $75,000 paid total. General rent of $9,000 also remains outside this illustration because it would have been paid anyway and no project-specific waste is assumed.

Suppose the supplier argues that performance would have left $10,000 of the expenditure unrecovered. Record that as a disputed recoupment adjustment, with its forecasts and assumptions. If established on that basis, the illustrative figure falls from $50,000 to $40,000. Until assessed, retain both scenarios without treating the allegation as an agreed deduction.

Do not deduct the withdrawn installation invoice again from the $50,000. It was never included. Equally, do not deduct the materials’ former book value as well as their net resale proceeds for the same recovery.

Prepare the Reliance Loss Schedule

Each line in a reliance loss schedule must connect the contractual commitment to its source payment and proposed adjustment. Give each expenditure item a stable reference that also appears on its supporting documents.

A useful working schedule contains the following fields:

Reconcile the payment register to the bank statements before reconciling the claim total. Match part-payments and credit notes. Remove duplicate counting where an internal transfer funds the account that pays the supplier. Keep an unresolved invoice match visible as an evidence issue rather than assuming a second expense.

Use an adjustment register for refunds and mitigation receipts. Cross-reference those credits into each alternative calculation so they are counted once in any chosen award. Keep the expectation calculation separately identifiable for the solicitor and expert, with an overlap column explaining amounts that concern the same loss.

For a statement-heavy matter, FinTrace saves lawyers and forensic accountants hours of conversion and transaction review. The service produces a searchable Excel ledger and a findings report with direct references to source PDF filenames and pages. Those references put payment evidence at hand while the team prepares the expenditure schedule.

Finish by checking that the net total can be rebuilt from the included items and individual adjustments. For the fictional transaction, that means reproducing $50,000 before the disputed recoupment adjustment and explaining exactly what evidence would change it.
