The Final Whistle: No whistleblowing protection for external job applicants

UK whistleblowing law protects workers from being treated unfairly or dismissed for speaking out about wrongdoing. But how far does that protection go? In Sullivan v Isle of Wight Council, the Court of Appeal confirmed it does not extend to external job applicants – unless they’re applying for NHS roles.

Who’s Protected?

Under s.47B of the Employment Rights Act 1996, whistleblowing protection applies to workers, including employees, agency workers, judges, and some self-employed NHS professionals. However, the law does not cover external candidates- except in the NHS, where specific protections apply during recruitment.

In this case, Ms Sullivan applied for a council job and raised concerns during the hiring process that may have amounted to whistleblowing. After being rejected, she claimed she was treated unfairly because of this. The Court of Appeal dismissed her claim, confirming she had no legal protection under whistleblowing law.

The Human Rights angle

The key consideration in Sullivan was whether, by excluding external job applicants (other than those for NHS roles who are given specific protection), the law protecting whistleblowers from detriment breached Article 14 of the European Convention on Human Rights (ECHR), read with Article 10 (freedom of expression). Article 14 protects individuals from discrimination on listed grounds and also if they belong to an ‘other status’. Judges had successfully argued in Gilham v Ministry of Justice that they were an ‘other status’ who had been discriminated against by not falling within whistleblowing protection and that the legislation should be interpreted to include them so that their right to freedom of expression was protected.  Ms Sullivan was trying to argue something similar as an external job applicant.

The Court acknowledged that being an external job applicant could count as an ‘other status’ under Article 14. But it ultimately found no unlawful discrimination. Applicants are simply not the same as current workers, and the purpose of whistleblowing protection is to support disclosures from people already in a working relationship. The Court also found the exclusion was justified – the aim was to protect public interest, and that aim was met by focusing protections on workers and NHS applicants.

Why it matters

The decision in Sullivan draws a firm line: only current workers and NHS job applicants are protected when they blow the whistle. For HR professionals, this is a reminder that while whistleblowing laws are broad, they don’t cover everyone – and external applicants remain outside the scope.ssociation. It is in the area of service provision that the ruling is likely to be most impactful.
