Abstract

Australian class actions bring litigation economics into court in a way ordinary bilateral settlements usually do not.

Settlement approval may expose legal costs, funding charges, administration expenses, releases, distribution arrangements and proposed net group-member return. But exposure is not attribution.

This paper addresses the proof point. It asks what material may support the asserted connection between an applicant-side economic step and a deduction later claimed from settlement value.

The conclusion is narrow. The paper proposes no new judicial rule. It is concerned with evidence and weight within existing settlement approval functions.

Central question

What evidence may support the attribution of deductions claimed from settlement value in class action settlement approval?

This paper explains how attribution differs from visibility and measurement. It considers when contemporaneous, objective material may assist courts in evaluating deductions without reconstructing privileged litigation strategy.

Key ideas

1. Exposure is not attribution

Settlement materials may identify a deduction without proving how that deduction became a claim on settlement value.

2. Visibility, measurement and attribution are different

When Cost Becomes Visible (paper 1a) concerns timing and visibility.

When Cost Becomes Measurable (paper 1b) concerns measurement.

When Cost Becomes Supervised (paper 1c) concerns attribution, evidence and weight.

3. Attribution is limited

Attribution matters only where the basis of the claimed deduction makes the connection material.

4. Proof comes before weight

Material relied upon for attribution assists only to the extent it proves the asserted attribution path.

5. The paper stays within existing judicial functions

It does not ask courts to adopt a new framework, expand settlement approval or reconstruct privileged litigation strategy.

Scope

This paper does not examine:

whether class actions are generally beneficial or harmful;
whether litigation funding should be encouraged or restricted;
whether settlement approval law should be reformed;
whether any deduction is inherently suspect; or
whether any legal service model should be preferred.

Its purpose is narrower.

It explains the evidentiary distinction between visibility, measurement and attribution.
