Not just another law firm, the emphasis at didlaw has always been about providing an exceptional level of client service. This means clear and practical advice, explained in plain English. It means going the extra mile for our clients to find the right solution.

We started in 2008, focusing on helping people who were having difficulties around health and disability at work. By 2018, we were widely recognised as the UK’s leading disability discrimination lawyers.

In 2019 didlaw began a new chapter in its story. Our MD, Karen Jackson joined forces with employment barrister, Elizabeth George, to embark on the next ambitious phase of the firm’s journey.

The two women have expanded the firm’s offering to provide the same level of expertise but across all areas of employment and discrimination law. And they are committed to making didlaw a truly values-driven firm in everything that it does. You can read more about the values that drive them on our website.

As the law currently stands, yes, you can, although this issue has been under scrutiny in the Court of Appeal in the joined cases of Barton Turns Developments Ltd v Treadwell and Rice v Wicked Vision Ltd [2024] EAT 29. The cases have been joined because they both deal with the same technical point.

The issue is whether an employee can bring a s.47B detriment claim against a colleague who decided to dismiss, as well as bring a s.103A automatically unfair dismissal case against their employer. The case of Timis & Sage v Osipov [2019] ICR 655 created new law when it determined that this is possible. That decision and the precedent it created are being challenged by employers, and it is this that the Court of Appeal has been asked to decide.

The Court of Appeal has now handed down its judgment.

Whilst the appeal was dismissed, the Court of Appeal made it clear that they did so because they were not free to depart from the precedent in Osipov. Had they been free to do so, they said they would have.

Permission to appeal to the Supreme Court was as good as given, so once again, we watch this space. Any application for permission is likely to succeed.

For now, a detriment claim can be brought against individual managers as well as an automatically unfair dismissal claim against the employing organisation. Was this dual liability ever the intention of Parliament? The law needs clarification.

One has to wonder how this will impact the conduct of senior managers dealing with issues around whistleblowing if they are opening themselves up to personal liability.

The content of this article is intended to provide a general guide to the subject matter. Specialist advice should be sought about your specific circumstances.
