In this article

The law provides a framework in which contracts can operate.

Parties must perform within the terms of the contract as a failure to do so will result in a breach.

However, when a contract involves illegality, matters are dealt with differently.

For the law to uphold illegal contracts would be contrary to the integrity of the legal system to help those who engage in criminal conduct.

What is an Illegal Contract?

Contracts with regard to certain types of subject matter are prohibited. For example, buying and selling organs online.

Contracts are illegal because they commit wrongs, whether that be criminal or civil.

Illegality is not confined to these areas as it also includes a range of other matters of public policy.

There are several sources of illegality:

  • All contracts expressly or impliedly prohibited by statute are illegal.
  • Illegality at formation: contracts which are created with the intention of committing an illegal act.
  • Illegal purpose: the contract has been created to achieve an unlawful/illegal goal.
  • Illegality when performed: Contracts which are created with no illegal intention, but on performance are illegal.

The subject matter of the agreement must relate to an illegal purpose that violates the law.

Consequences of illegality in contracts:

The principle of illegality is often raised in an action for breach of contract, as a possible defence.

The usual laws surrounding contracts tend to not apply.

As a general rule – “Ex turpi cause non oritur actio”, no action arises from a base (or disreputable) cause, but this is not always the case.

Judicial remedies can be withheld because of the illegality of the contract.

The consequences will not always be a denial of remedy.

Considerations to be made

The courts approach illegality in a multifactorial approach (Patel v Mirza [2016] UKSC 42) by weighing three matters.

Their main focus to explore is whether there may be inconsistency damaging to the integrity of the legal system. (Stoffel v Grondona [2020] UKSC 42).

They must:

  • Consider the policy underlying the prohibition which gives rise to illegality.

What would be the impact to leave things as they stand rather than granting the relief sought by the claimant?

  • Matters of public policy which may be affected by the decision to deny relief/remedy to a party. Would doing so render other policies unimportant?

Taking into account any other relevant public policies which may be rendered ineffective or less effective by the denial of the claim. (Hounga v Allen [2014] UKSC 47)

  • The last consideration is only revenant if balancing policy considerations suggest a denial of the claim.

Whether denial of relied will be proportionate to the nature and degree of the illegality involved. In some cases illegality may be such a tenuous connection that it is disproportionate to hold the entire transaction to be unenforceable.

A candid photograph taken inside the modern, open-plan office of Gregory Abrams Davidson Solicitors. Five diverse employees are visible. Two men are seated at a wooden desk in the foreground, smiling at a woman in a grey sweater who is offering one of them a coffee cup from a tray, which also holds a small sign reading 'Thank You, Team! Acts of Kindness' and a plate of cookies. Another woman is standing to the right, smiling and looking down, and another employee is working in the background by the window. The company logo is prominently displayed on a large white wall panel, alongside a window view of a city skyline with historic and modern buildings, a '45 Years 1980 - 2025' plaque, and a 'CORPORATE SOCIAL RESPONSIBILITY' poster listing charity support logos (Macmillan, Wear It Pink, Children in Need). The office has neat desks, multiple computers, and bright overhead panel lighting.
