The House of Lords allowed the appeal by a majority of four to one, restoring the judgment of Browne J. The decision attracted immediate and lasting attention as a landmark in the constitutional relationship between the judiciary and the executive, addressing both the substantive limits of administrative jurisdiction and the extent to which Parliament may, by statutory language, exclude curial oversight of those limits.
Issues for Determination
The primary issue before the House of Lords was whether the ouster clause contained in section 4(4) of the Foreign Compensation Act 1950 was effective to preclude judicial review of the Commission's determination. This required the court to consider the scope and constitutional limits of parliamentary ouster provisions, and to determine whether such clauses can lawfully immunise administrative decisions from all judicial scrutiny regardless of the nature of the error committed.
Subsidiary to the above was the question of statutory construction: whether the Commission had correctly interpreted the Order in Council made under the 1950 Act when it held that the nationality of TEDO, as a successor in title, was relevant to Anisminic's entitlement to compensation. Closely connected to this was the broader jurisprudential question of how to distinguish errors of law that go to jurisdiction — and thus render a decision a nullity — from errors of law made within jurisdiction, which at the time of the decision were not generally susceptible to judicial correction.
Taken together, these issues raised a fundamental constitutional question: can Parliament, through the use of an ouster clause, render an administrative body immune from the supervisory jurisdiction of the courts, even where that body has acted beyond the legal limits of its authority? The House of Lords' answer to this question has shaped the constitutional architecture of administrative law in England and Wales ever since.
The Court's Reasoning
The majority's reasoning proceeded in two distinct but closely interlocking stages. The first concerned the correct interpretation of the Order in Council and whether the Commission had erred in law. The second — and constitutionally more momentous — concerned the effect of the ouster clause on any such error. Lord Reid delivered the leading speech, and Lords Pearce and Wilberforce each offered important and complementary analyses.
On the question of statutory construction, the majority held that the Commission had plainly misconstrued the Order in Council. The relevant provisions were directed at cases where the original owner of the sequestrated property had since disposed of it, and the successor in title was bringing the claim in place of the original owner. Since Anisminic was itself the original owner and was bringing the claim in its own right, the successor in title condition simply had no application to its circumstances. By importing the nationality of TEDO into its assessment, the Commission had applied a condition that was legally irrelevant on the facts before it and had thereby asked itself the wrong question.
The court then turned to the more difficult constitutional issue: whether the ouster clause in section 4(4) could nonetheless render this erroneous determination unchallengeable. The starting point for Lord Reid was the recognition that the word "determination" in the ouster clause must be given a meaning consistent with the overall statutory scheme. He observed that Parliament, in conferring jurisdiction on the Commission, necessarily defined the limits of that jurisdiction. A purported decision made outside those limits is not a "determination" within the meaning of the statute at all — it is a nullity, a non-decision, which the ouster clause simply has no occasion to protect.
Lord Reid enumerated a range of circumstances in which a tribunal may be said to have exceeded its jurisdiction and thus produced a nullity: where it acts in bad faith; where it refuses to consider a relevant matter or takes into account an irrelevant matter; where it misconstrues the scope of its enabling legislation; or where it fails to apply the correct legal test. This enumeration was significant because it moved the concept of jurisdictional error beyond the narrow category of initial or collateral questions of fact and extended it to errors of law that infect the decision-making process itself. In the present case, the Commission's misreading of the Order in Council fell squarely within this expanded conception of jurisdictional error.
Lord Wilberforce's reasoning added important depth by identifying the logical incoherence of any contrary view. If an ouster clause could protect decisions tainted by jurisdictional error, the practical consequence would be that an administrative body could expand its own jurisdiction at will, simply by misconstruing the law in a self-serving direction, without any possibility of correction. This would be fundamentally inconsistent with the rule of law, under which public bodies are creatures of statute and must act within the limits Parliament has lawfully assigned to them. An ouster clause, properly understood, protects only those decisions that fall within the area of authority Parliament has conferred — it cannot extend that area or validate action taken beyond it.
The court expressly distinguished the earlier decision of the House of Lords in Smith v East Elloe Rural District Council [1956] AC 736, where an ouster clause in planning legislation had been given broad effect. The majority in Anisminic treated East Elloe as either decided on its own particular statutory context or as turning on the absence of any jurisdictional error in that case, and declined to treat it as authority for the proposition that an ouster clause can immunise a jurisdictional nullity. The distinction between the two cases was thus characterised as turning on the substantive quality of the underlying error rather than on the precise wording of the ouster provision.
The court also considered R v Medical Appeal Tribunal, ex p Gilmore [1957] 1 QB 574, in which Denning LJ had drawn a distinction between "shall not be questioned" clauses and "shall be final" clauses, suggesting the latter preserved the possibility of review for error of law on the face of the record. The House of Lords in Anisminic went considerably further than this. Rather than merely preserving the old error-of-law-on-the-face-of-the-record jurisdiction, their Lordships held that any error of law going to jurisdiction — irrespective of whether it appeared on the face of the record — was reviewable, because such an error rendered the decision a nullity falling outside the scope of the ouster clause altogether.
The earlier decision in R v Governor of Brixton Prison, ex p Soblen [1963] 2 QB 243 was distinguished on the grounds that it was concerned with the exercise of a discretion within an uncontested jurisdiction, rather than with the anterior question of whether jurisdiction had been lawfully exercised at all. The logical structure of the majority's reasoning was thus consistent: the ouster clause operates as a shield for intra-vires decisions but cannot transform an ultra vires act into a valid determination merely by attaching a label of finality to it.
Lord Pearson, in his dissent on the ouster clause point, accepted that the Commission had erred in law but took the view that the ouster clause, on its plain and ordinary meaning, precluded any judicial challenge. He considered that Parliament's intention in enacting section 4(4) was to achieve finality precisely in cases of this kind, and that to read the ouster clause as impliedly subject to a jurisdictional exception was to substitute judicial preference for parliamentary language. This minority view reflects a more textualist approach to statutory interpretation, but it has not prevailed in subsequent jurisprudence.
An important consequence of the majority's reasoning — one that only became fully apparent in subsequent decades — was the effective collapse of the distinction between errors of law within jurisdiction and errors of law going to jurisdiction. If, as Lord Reid suggested, any misinterpretation of the law defining a tribunal's authority constitutes a jurisdictional error, then virtually all errors of law committed by an administrative tribunal become potential jurisdictional errors. This convergence was made explicit by the House of Lords in R v Hull University Visitor, ex p Page [1993] AC 682, where the majority held that all errors of law made by inferior tribunals are in principle reviewable, with only a narrow exception for bodies interpreting their own constitutive instruments.
The decision in Pearlman v Keepers and Governors of Harrow School [1979] QB 56 illustrates the difficulty of containing the Anisminic principle within neat doctrinal boundaries. In that case, the Court of Appeal was divided on whether an error of law by a county court judge in construing statutory language was a jurisdictional error or merely an error within jurisdiction. Lord Denning MR drew the logical implication of Anisminic to its conclusion by suggesting that the distinction between the two categories had been all but abolished, while Geoffrey Lane LJ preferred a more cautious view. The tension between these approaches reflects the generative instability introduced by the Anisminic principle into the law of judicial review.
The constitutional dimension of the majority's reasoning was reinforced by the implicit invocation of the rule of law as a background principle against which statutory ouster provisions must be read. Their Lordships reasoned that Parliament legislates against a constitutional presumption in favour of access to the courts and the right to have unlawful executive action corrected by the judiciary. An ouster clause, however broadly worded, cannot be taken to have displaced this presumption in relation to decisions that are not, in law, decisions at all. Clear and unambiguous language would be required to achieve such a result — and, the majority implied, it is doubtful whether even the clearest language could be constitutionally effective for this purpose.
Holding
The House of Lords held, by a majority of four to one, that the Foreign Compensation Commission had exceeded its jurisdiction by misinterpreting the Order in Council and by importing into its assessment a condition — the nationality of TEDO as successor in title — that had no legal relevance to Anisminic's claim. The Commission's purported determination was accordingly a nullity and had no legal effect.
The ouster clause contained in section 4(4) of the Foreign Compensation Act 1950 was held to be ineffective to prevent judicial review of this nullity. An ouster clause cannot protect a decision that is not in law a decision at all. The clause operates only within the sphere of the Commission's lawful authority and cannot extend the Commission's jurisdiction or validate acts taken outside it.
The appeal was allowed and the declaration granted by Browne J at first instance was restored. The decision of the Court of Appeal was reversed. The practical effect was that Anisminic was entitled to have its claim reconsidered by the Commission on the correct legal basis, without the erroneous nationality condition being applied to it.
