## Bottom line

Our **Calderbank Letter v4** is structurally sound and consistent with current authority. The recent QCA decision in *Metro North Hospital and Health Service v Stewart* [2024] QCA 226 does **not** invalidate it (it's a Calderbank, not a UCPR Part 5 offer). However, three observations and one strategic recommendation arise.

## Observations

### 1. Calderbank validity — letter is compliant

The v4 letter contains all five Calderbank essentials confirmed in *Built Qld v Pro-Invest (No 3)* [2022] QSC 62 and the subsequent commentary:

- ✅ Marked "Without Prejudice Save as to Costs"
- ✅ States it is made pursuant to *Calderbank v Calderbank* [1975] 3 All ER 333
- ✅ Open for 28 days (well above the 14-day minimum and longer than the construction-case "1 day" patterns that have been discounted)
- ✅ Foreshadows application for indemnity costs on unreasonable rejection
- ✅ Sets out the basis of the genuine compromise — extensive analysis of the plaintiff's weaknesses (restraint width, absence of confidentiality regime, Faccenda Chicken know-how, fiduciary duty defects, repudiation, damages unquantified)

The "genuine compromise" section explicitly acknowledges the Defendants' own risks (data export, quantum of commission, repudiation factual disputes) before identifying the offer as a compromise of those competing risks. That is exactly the pattern *Built Qld* approves.

### 2. Why we should also consider serving a UCPR Part 5 offer in parallel

A Calderbank offer leaves the costs question to a discretionary "unreasonableness" assessment. A compliant UCPR offer engages **r 361** automatically (subject to the offeree showing some other order is appropriate).

Under the **post-23 June 2023** rules, a defendant who serves a compliant r 353 offer, and where the plaintiff fails to obtain a more favourable order, is entitled to:
- the plaintiff's standard costs to and including the day of service of the offer; and
- the plaintiff's **indemnity** costs after the offer.

If we structure a parallel UCPR offer to mirror the Calderbank quantum, we have two costs-protection mechanisms running. The defendant in *Built Qld* (Williams J) used exactly that approach — formal UCPR offer + Calderbank — and recovered indemnity costs.

### 3. *Metro North v Stewart* drafting considerations for any UCPR offer we serve

If we draft a UCPR Part 5 offer, we must avoid the *Metro North* trap:

- **Do not** leave any component "to be agreed", "to be assessed" or "subject to further agreement" in the body of the offer.
- The current Calderbank offers $45,000 to the **First Defendant** in full and final settlement of the **Counterclaim**, with **discontinuance** of the claim and counterclaim, **no order as to costs**, and a deed of release.
- For a UCPR Part 5 version to be valid, every component must be on the face of the offer. The "deed of settlement and release containing mutual releases, a confidentiality clause, and no admissions" is acceptable provided we constrain it (per *Built Qld*) to "reflecting" the offer terms.
- We should specify that any deed will be on terms "mutually acceptable, reflecting only the terms of this offer".

### 4. Quantum of compromise — the QCA "extent of compromise" line

Recent QCA authority (Applegarth J, Morrison JA agreeing) confirms r 360 does **not** require substantial compromise. Even a modest discount from the agreed/expected quantum will engage indemnity costs if the offeror betters the offer at trial.

Application here: the Counterclaim claims approximately $88,000 (unpaid commission ~$68,000 + unauthorised deduction ~$20,000) plus FW Act penalties up to $93,900 per contravention. The current Calderbank offer of $45,000 represents a ~50% discount on the principal Counterclaim value (excluding penalties). On any view this is a substantial compromise — if anything, it may be too generous to engage maximum costs leverage.

For the UCPR Part 5 version, consider a **higher** offer (e.g. $55,000–$60,000) which:
- still preserves a "no order as to costs" outcome more favourable to JPS than the inevitable cost burden of running the case;
- but is closer to the realistic Counterclaim recovery, making it harder for the plaintiff to argue the offer was not bettered.

## Strategic recommendation

**Serve a parallel UCPR Part 5 offer alongside the Calderbank**, on the same day or close to it. Structure as follows:

1. **Calderbank Letter v4** (as drafted) — fuller exposition of the plaintiff's difficulties, basis for indemnity costs application, $45,000 + discontinuance + no order as to costs, deed of release.

2. **UCPR Offer to Settle (separate document)** — formal r 353 offer, every component quantified:
   - Within 28 days of acceptance, the Plaintiff pays the First Defendant $X (consider $50,000–$55,000) inclusive of interest under s 58 *Civil Proceedings Act 2011* (Qld) calculated to date of acceptance, in full and final satisfaction of the Counterclaim.
   - The proceeding (claim and counterclaim) be discontinued.
   - Each party bear its own costs.
   - Optional: deed of settlement and release on terms "mutually acceptable, reflecting only the terms of this Offer to Settle".
   - Open for 14 days (or longer; r 355(1) requires at least 14 days from service).
   - Statement that the offer is made under Chapter 9, Part 5 of the UCPR (r 353(3)).

3. **r 361A back-up** — in correspondence, foreshadow that if the claim is dismissed (e.g. on a summary judgment / strike-out application we may bring on the restraint-of-trade pleading) the offer will trigger r 361A and indemnity costs from the date of service.

## File actions

- [ ] Discuss with Mark before serving the second offer
- [ ] If approved, draft UCPR Part 5 offer in parallel with Calderbank v5 (or v4 as final)
- [ ] Update billing narrative to record this research and any strategic memo arising
