Tainting illegality

  • Alexander F H Loke (a1)


The assertion of contractual rights may be defeated by the illegality defence, not because their creation is offensive to public policy but by reason of an illegality that ‘taints’ these rights. To date, no analytical framework has been developed for understanding how these tainting rules are connected to one another. The Tainting Illegality Framework (TIF) presented in this paper seeks to fill this gap in current legal scholarship by exploring, first, the linkages between the rules by which contract rights are tainted and, secondly, the theoretical underpinnings that explain the existing tensions and that will continue to shape the law in this area. The suggested analytical approach enriches and increases the sophistication of the current approaches by considering how their application is shaped by considerations of proximity and the nature of the contaminating illegality. The framework recognises the value of the existing rules, and seeks to enrich the analytical approach by suggesting how their application can more transparently reflect the policy rationale for applying the illegality defence.

10. In this paper, ‘proximity’ and ‘remoteness’ are used interchangeably to denote the distance or the closeness of the relationship between the contaminating illegality and the contractual right.

11. See s 3(a) (which examines, inter alia, the rule against indemnities for criminal penalties) and s 3(b) (which investigates tainting by participation).

12. CP 189, above 9. The Consultation Paper (amongst other matters) reviewed its earlier recommendation that legislation should be introduced to give courts a statutory discretion to decide whether the illegality defence should be applied to private law rights: see Law Commission Illegal Transactions: the Effect of Illegality on Contracts and Trusts Consultation Paper No. 154 (1999). In CP 189, the Law Commission took the view that a broad statutory scheme would introduce new uncertainties into the law, and that except for certain trusts, the illegality defence as applied to other private law rights can be satisfactorily developed through judicial decisions. A statutory discretion to decide on the effect of illegality was thus recommended only for a limited class of trusts. The final report tracks those of the consultation paper: Law Commission The Illegality Defence, No. 320 (2010).

65. This would be consistent with Cunard v Hyde (No. 2) (1859) 2 El & Bl 1, which implicates tainting illegality by participation (s 3(d)). Here, the master of a vessel contravened the Customs Consolidation Act 1853 by carrying cargo on the deck of the ship during the winter months. The insured's claim against the insurer was denied on the ground that ‘the insured knew of the master's act, in the sense of consenting to it and wanting it to be done’. (Cunard v Hyde (No. 1) (1858) El & Bl 670 at 677 where the insurer's plea of illegality was initially found to be defective because it had failed to plead these matters.)

67. Nourse LJ opined, ‘… I think that if the plaintiff had formed that intention at or before that time he would have been unable to recover against the defendant. the contract would have been tainted by the plaintiff's intention partially to perform it by doing an illegal act.’ Beldam and Simon Brown LJJ expressed similar sentiments in their separate judgments.

105. Buckley is sympathetic to the notion that the ‘degree of turpitude’ of an illegality impacts on the participation rule. (‘The insistence that mere “knowledge” is insufficient, in the absence of participation, to warrant forfeiture of an “innocent” party's claim, is only tenable if the other party's illegal scheme is not of such gravity that anyone becoming aware of it should immediately refuse to proceed with the transaction’: above 29 at [4.21].) The argument here develops Buckley's instinct that Lord Goff's ‘no degrees of iniquity’ dictum is often interpreted too broadly. However, while Buckley seems to see “degrees of turpitude” as featuring in a discretionary approach, this paper suggests that the nature of the offence as a material consideration in determining the correct common law rule to be applied. This does not involve a ‘discretionary approach’ sensu stricto.
