How will the public interest requirement for protected disclosures be applied in the light of Chesterton? Where are we now on the issue of liability of the individuals who cause an employer to dismiss (Osipov; Jhuti) and what are the ramifications? What are the implication of Beatt for employers who take action in the belief that the disclosure isn’t protected?

These and other issues in the developing field of whistleblowing protection were will be tackled by Jeremy Lewis, Martin Fodder (both of Littleton Chambers) and Jack Mitchell (Old Square), co-authors of Whistleblowing: Law and Practice 3rd Edition, Oxford University Press (2017).
