The power of the directors to bind the company, or authorise others to do so, is deemed not to be constrained by the company’s constitution. This means that a third party dealing with a company in good faith need not concern itself about whether a company is acting within its constitution. 126 Subsection (2)(b)(i) of the section replaces part of section 35B of the 1985 Act: an external party is not bound to enquire whether there are any limitations on the power of the directors. The first limb of section 35B (which refers to the memorandum) has not been carried forward. This is concerned with restrictions in a company's constitution that limit a company’s ability to act and consequently the powers of the directors to bind the company (the so called "ultra vires rule"). Under the Act, the objects no longer affect the company's capacity to act and so this limb is not necessary.
