Cases considering section 33 (22)

Lehtimäki and others v Cooper

[2020] UKSC 33 · 29 July 2020

A company’s constitution binds the company and its members as though they had covenanted to observe it. The provision formed part of the contract-and-statute framework tailoring a charitable member’s fiduciary duties. (see paras [73]; [92])

Lehtimäki v The Children's Investment Fund Foundation (UK) & Ors

[2018] EWCA Civ 1605 · 6 July 2018

The court uses the provision to show that a company’s constitution binds the company and its members, while emphasising that its force derives from statute and the general law as well as agreement. (see para [37])

Zavarco PLC v Tan Sri Syed Mohd Yusof Bin Tun Syed Nasir

[2026] EWHC 338 (Ch) · 23 February 2026Defines

Confirms that money payable by a member to the company under its constitution is an ordinary contract debt. The provision does not prevent a separate analysis of when the contractual cause of action accrued. (see paras [22]; [29]; [34])

Explanatory note

108.Subsection (1) of this section replaces section 14(1) of the 1985 Act. Its effect is that the provisions of a company’s constitution constitute a special kind of contract, whose terms bind the company and its members from time to time. Like section 14(1), the provisions of this section are excepted from the general principle set out in section 1 of the Contracts (Rights of Third Parties) Act 1999, so that provisions of a company’s constitution will not confer any rights on persons other than the company and its members. Unlike section 14(1), section 34 refers to “a company’s constitution”, rather than its “memorandum and articles”. This reflects the new division of formation and constitutional information between the memorandum, articles and other constitutional documents noted above.

109.The language in subsection (1) has been updated but there is no change to the law (the provision continues to reflect what the law has always been: in particular a company’s constitution binds both the company and its members).

110.Subsection (2) replaces section 14(2) of the 1985 Act. It provides that amounts which a member of a company is obliged to pay to it under its constitution are debts due to the company. In England and Wales and Northern Ireland, such debts are ordinary contract debts.
