Qualifying disclosures and reasonable belief

For the law to protect you, your concern must be a "qualifying disclosure." That phrase has two working parts, and both are more generous to the whistleblower than people expect.

You must disclose information

A qualifying disclosure needs some substance: facts, an account of what you saw, a document, a description of events. A bare allegation with no information at all, such as "management are corrupt" with nothing behind it, is on weaker ground than "I saw invoices approved for a supplier that does not appear to exist, on these dates." The more concrete the information, the stronger the disclosure, which is also just good practice when you want the concern taken seriously.

Reasonable belief in the public interest

You must reasonably believe two things: that the information tends to show one of the six categories of wrongdoing, and that disclosing it is in the public interest. The public interest test does not require the concern to affect millions of people. A concern affecting a group of workers, customers, or service users can qualify. What the test filters out is a complaint that is purely about your own private position.

You do not have to be right

This is the part worth remembering above everything else. The law protects a reasonable belief, not a proven fact. If you honestly and reasonably believed the wrongdoing was occurring, you are protected even if a full investigation later shows you were mistaken. The question a tribunal asks is whether your belief was reasonable at the time, on the information available to you.

The flip side is that a disclosure you know to be false is not protected, and deliberately making false allegations is likely to be a disciplinary matter in its own right. Honest and reasonable is the standard. Certainty is not required, and neither is being correct.
