[2025] EWCA Civ 1466

Part IVA was inserted in the 1996 Act by section 1 of the 1998 Act and has been amended since then. Section 43A defines a ‘protected disclosure’ as “a qualifying disclosure (as defined by section 43B) which is made by a worker in accordance with any of sections 43C to 43H”. As advertised, section 43B duly defines which disclosures qualify for protection. Section 43J(1) makes void any provision in an agreement in so far as it purports to stop a worker from making a protected disclosure. As noted above, section 43K extends the meanings of ‘worker’ and ‘employer’ for the purposes of Part IVA.
