Of course sometimes I am wrong, but since you posted, I decided I would ask ChatGPT 4o - which is legally capable, BTW. I post below VERBATIM, my question and its response. (None of the text after my question is mine):
MY QUESTION:
On page 19 of the Labour Party manifesto 2024, it makes comment about commitments with regards to National Insurace. One view is that it is clear that the commitment is not to raise National Insurance at all, both Employees and Employers. Another view is that it is clear that they only meant Employee. Please read the manifesto, and give me your opinion, as if you were a judge in a court of law, having to arbitrate on this.
CHATGPT:
Certainly. Here's an objective legal-style analysis of the 2024 Labour manifesto statement regarding National Insurance and whether an increase in Employer’s National Insurance would be consistent with it.
Key Wording from the Manifesto (Page 19)
There is no qualifier distinguishing between types of National Insurance (e.g., employee vs. employer).
Legal Interpretation: Hypothetical Analysis
1. Literal (Textual) Interpretation
Under standard principles of legal drafting and statutory interpretation:
- The term “National Insurance” is used without qualification.
- In law and public policy, “National Insurance” includes both employee and employer contributions.
- In the absence of an explicit limitation (e.g. “employee’s National Insurance”), the ordinary meaning would be interpreted to encompass the whole structure of National Insurance contributions.
A court assessing this statement would likely conclude that the use of the unqualified term "National Insurance" includes both employee and employer elements.
2. Purposive Interpretation
Looking at the intent and purpose behind the statement:
- The commitment is part of a broader pledge not to increase taxes on “working people”.
- The wording appears designed to offer reassurance about overall tax burdens relating to work.
- If the intention were to exclude employer contributions from the commitment, it would be reasonable to expect that this would have been explicitly stated.
Given the context, a purposive reading would likely reinforce that the term was meant to cover all NI contributions affecting work and employment.
3. Legitimate Expectation and Public Interpretation
In public law, the concept of
legitimate expectation often arises where the government makes clear, unambiguous representations.
- The manifesto was a central campaign document, heavily vetted and widely disseminated.
- It is likely to have generated a public expectation that no part of National Insurance would be increased, including the employer element.
- Where ambiguity exists, interpretive rules such as contra proferentem (against the drafter) would tend to favour the more inclusive reading.
4. Subsequent Ministerial Interpretations
Subsequent clarifications from ministers have suggested the commitment was only intended to cover employee contributions. However:
- These post-hoc interpretations do not change the original meaning of the text.
- Courts do not typically give weight to ex post facto reinterpretation where the original language was unqualified and likely to lead to a broader public understanding.
Summary Table
| Aspect | Analysis |
|---|
| Plain Text | “National Insurance” is unqualified – interpreted to include all forms. |
| Context | Part of a promise not to raise taxes on working people. |
| Omission of Qualifier | Absence of “employee’s” implies intention to include all contributions. |
| Post-manifesto Clarifications | Do not override plain or purposive meaning. |
| Legal Interpretation (Hypothetical) | Likely to conclude increase in Employer NI breaches the stated commitment. |
Hypothetical Judicial View
If this were assessed like a contractual or statutory commitment, a court would likely conclude:
This analysis assumes a purely hypothetical legal lens, as manifesto pledges are not legally binding. Nonetheless, under standard principles of legal drafting and interpretation, the increase in Employer’s National Insurance would likely be viewed as inconsistent with the unqualified commitment not to increase National Insurance.
